This study aimed to photographically compare the ridge width at baseline, immediately postsurgery and at 4 weeks and 8 weeks thereafter after using 2 different ridge-preservation procedures. Part I of this clinical study randomly allocated a total of 26 extraction sites from 17 patients to either study group using a computer-generated randomization assignment software. Only 16 sites were qualified for this final analysis. Group I received a cortico-cancellous allograft bone chip (CCBC) mix and a dense polytetrafluoroethylene (dPTFE) barrier membrane, and group II received a type I bovine Achilles tendon collagen plug with bioactive resorbable calcium apatite crystals (CPCAC). Adobe Photoshop CS3 was used to measure the ridge width at the extraction site at 4 distinct time points: baseline (T0), immediately postoperatively (PO) (T1), 4 weeks PO (T2), and 8 weeks PO (T3). The experimental design was a typical repeated-measures design. Statistical significance was evaluated at p < .0042 to adjust for multiple comparisons. No statistically significant differences were found between groups I and II at any assessment regardless of whether the assessment was expressed as an absolute measurement in millimeters or as a percentage of change from baseline assessed before surgery. However, the percentage of ridge width reduction significantly increased over time within each group when comparing each pair of time points except for the T0-T1 (p < .0001) and T2-T3 (p < .0001) comparisons. The sockets that received CPCAC showed similar ridge width reduction when compared with the group that received CCBC with dPTFE at T3. There was no statistically significant difference in ridge width within each group for both T0-T1 and T2-T3 (p > .0042). However, the percentage of width reduction significantly increased over time within each group, when comparing each 2 time points except for the T0-T1 and T2-T3 comparisons.

There are limited studies analyzing the accuracy of desktop scanners with scan bodies made of different materials but of the same design. The purpose of this in vitro study is to examine the effect of scan bodies made of titanium and polyetheretherketone (PEEK) on the accuracy of desktop scanners that have different scanning technologies (white light vs blue light). Two upper jaw models with a missing left second premolar were obtained. An implant (Bilimplant) was placed in the area where the missing tooth was located. The titanium and PEEK scan bodies were torqued, and an industrial scanner obtained reference data. A total of 40 scans were recorded using two desktop scanners (Dentium and Kivi). Ti-Dentium, Ti-Kivi, PEEK-Dentium, and PEEK-Kivi were identified as the four test groups. Each STL file was imported into Geomagic for reverse engineering. The deviation between the experimental scan and the reference data was analyzed using a best-fit algorithm to determine the accuracy of each scan. Deviation values were compared using nonparametric tests. The average deviation values ± standard deviation observed across the groups were 65 ± 4.5 μm, 81 ± 3.1 μm, 24 ± 5.4 μm, and 47 ± 9.1 μm, respectively. Group Ti-K exhibited the highest average deviation, whereas Group PEEK-D demonstrated the lowest. A statistically significant difference was found between all groups (P < .05). Within the limitations of this in vitro study, PEEK scan bodies and white light scanners demonstrated superior accuracy, which may be clinically relevant in high-precision implant restorations.

Accurate knowledge of anatomical structures is essential for safe and effective dental implant placement. Although conventional imaging modalities provide valuable diagnostic information, their inherent limitations may hinder comprehensive anatomical assessment. Cone beam computerized tomography (CBCT) has emerged as a reliable 3D imaging technique, offering high-resolution, cross-sectional views for precise evaluation. The canalis sinuosus (CS), a bony canal carrying neurovascular bundles from the infraorbital canal, is frequently overlooked due to its subtle radiographic presentation. This report emphasizes the importance of CBCT in identifying anatomical variations by presenting a rare case involving complications related to the CS following implant placement in the posterior maxilla. In the present case, a 50-year-old male patient underwent dental implant surgery after radiographic assessment via orthopantomography. Postoperatively, the patient experienced persistent, pressure-like pain in the upper left first molar region. Despite treatment with analgesics and pregabalin, the symptoms continued, and CBCT revealed the implant compressing the anterior superior alveolar nerve due to CS invasion. Following implant removal, the patient's symptoms resolved completely within 1 week. At the 3-month follow-up, the site showed bone regeneration without pathological findings, and the patient remained asymptomatic. This case underscores the necessity of considering anatomical variations of the CS in all maxillary procedures to prevent iatrogenic complications. CBCT imaging is strongly recommended for accurately identifying the CS and determining its anatomical course, thereby minimizing the risk of surgical complications.

There is a dearth of clinical studies comparing the primary (PS) and secondary stability (SS) of nano-hydroxyapatite-coated, sandblasted, and acid-etched (SAE) implants placed in the posterior maxilla. The null hypothesis is that there is no difference in the primary and secondary outcomes of nano-hydroxyapatite-coated and SAE implants placed in the posterior maxilla. The aim was to assess the primary and secondary outcomes of nano-hydroxyapatite-coated and SAE tapered implants placed in the posterior maxilla. The study employed a triple-blinded, randomized, controlled trial design. Information regarding the patients' age, gender, and duration of edentulism in the maxillary molar region was collected using a structured questionnaire. Participants were randomly divided into 2 groups: group 1 was individuals who received nano-hydroxyapatite-coated implants (n = 26), and group 2 was individuals who received SAE implants (n = 26). The PS was measured immediately after implant placement, and SS was assessed at 4 and 6 weeks and 4 months of follow-up. Group comparisons were performed, and the level of significance was set at P < .05. At 4 (P < .01) and 6 weeks (P < .01) of follow-up, SS was significantly higher in group 1 than in group 2. There was no difference in SS at 4 months of follow-up in groups 1 and 2. There was no statistically significant correlation between implant stability and age, gender, implant dimensions, or insertion torque. Due to the stringent inclusion criteria and the use of a convenience sampling design, it is challenging to draw definitive conclusions about the effects of nano-hydroxyapatite-coated versus SAE implants on primary SS in the posterior maxilla.

This paper explores the clinical and aesthetic performance of zirconia dental implants with a focus on soft tissue outcomes. Through the presentation of three distinct patient cases involving the placement of ceramic implants, the study highlights the favorable biological and aesthetic integration of zirconia in challenging clinical scenarios. Emphasis was placed on peri-implant soft tissue health, contour stability, and the overall mucogingival response following implant placement and restoration. In all cases, the soft tissues exhibited excellent healing, with well-adapted, inflammation-free mucosa and high levels of patient satisfaction regarding esthetic results. These findings underscore the capacity of zirconia implants to support optimal soft tissue architecture and suggest their valuable role in modern implant dentistry, particularly in esthetically sensitive areas.

Effective postoperative pain control is essential for patient comfort following dental implant surgery. This double-blind, randomized clinical trial evaluated the efficacy of 0.3% benzydamine hydrochloride (BNZD) spray, an anti-inflammatory and topical analgesic agent, compared with placebo in patients undergoing single posterior implant placement. Thirty healthy adults were randomly allocated to either BNZD (n = 15) or placebo (n = 15). Pain intensity was assessed using a visual analog scale (VAS) at 3, 6, 18, 24, 48, and 72 hours postoperatively. The frequencies of spray use and the number of rescue analgesic tablets taken were also recorded. The VAS scores decreased progressively in both groups with no significant difference in immediate postoperative pain. However, a significant reduction in pain was observed at 18 hours in the BNZD group. Notably, the BNZD group reached a VAS score of 0 by 72 hours, whereas the placebo group continued to report residual pain. A significantly lower frequency of spray application was observed in the BNZD group (P = .03). Although not statistically significant, fewer rescue analgesics were used in the BNZD group. These findings suggest that 0.3% BNZD spray may reduce the frequency of analgesic use and expedite pain resolution following implant surgery. Although overall pain reduction was similar between groups, the earlier achievement of pain-free status with BNZD suggests potential clinical benefit. Further studies with larger cohorts are recommended to confirm its efficacy.

This study aims to compare the incidence of sinus membrane perforation between osseodensification and osteotome crestal sinus lift techniques when 5 mm of residual bone is present beneath the sinus floor. Additionally, it seeks to identify when the perforation most commonly occurs-during instrumentation, bone grafting, or implant insertion. A split-mouth design using 20 sinuses from 10 fresh human cadaver heads were employed. One side underwent a bone-added osteotome crestal sinus lift, while the other side received an osseodensification lift. Membrane perforation was recorded through video analysis. Statistical analysis was performed. Sinus membrane perforation occurred in 40% of the osteotome group and 50% of the osseodensification group, with no significant difference between the two (P = .564). Most perforations occurred during implant placement (20% in the control group and 40% in the test group), but this difference was not statistically significant (P = .480). Perforations during drilling were observed in 10% of test sinuses and 20% of the control group, but this difference was not statistically significant (P = .317). No perforations occurred during bone graft placement. There was no significant difference in the incidence of membrane perforation between the osseodensification and osteotome groups. However, a higher incidence during implant placement suggests potential limitations in the predictability of crestal sinus lift procedures with 5 mm of residual bone. Further research is needed to optimize outcomes and predictability in crestal sinus lift procedures.

The Socket Shield Technique (SST) has emerged as a promising approach for preserving facial bone and soft tissue contours during immediate implant placement in the esthetic zone. In this technique, the buccal portion of the tooth root-the socket shield-is intentionally retained with its periodontal ligament and blood supply to preserve the facial bone and support peri-implant soft tissue architecture. However, variations in shield morphology, thickness, and implant-shield gap management remain clinically significant and technique-sensitive. This case report presents a step-by-step protocol for a modified SST (M-SST), featuring a standardized 1.0-1.5 mm C-shaped shield reduced to the bone crest, and a fully guided digital workflow. A 39-year-old healthy, nonsmoking female with a hopeless maxillary central incisor (#8) underwent atraumatic extraction, buccal root shield preparation, and immediate implant placement. The socket shield was thinned to 1.0-1.5 mm, extended interproximally to preserve papillae, and reduced to the alveolar crest. A 3.3 × 16 mm Straumann BLT implant was placed palatal to the shield using a fully guided approach. Autologous particulate bone harvested from the maxillary tuberosity was placed because the implant-shield gap exceeded 2 mm. A screw-retained polymethyl methacrylate provisional crown was delivered on the day of surgery using a prefabricated Straumann Variobase NC abutment. Follow-up at 1, 3, and 12 months confirmed excellent soft tissue volume stability, intact papillae, and complete bone fill between the shield and implant on cone-beam computed tomography. No complications such as shield exposure, displacement, or soft tissue recession were observed. A final zirconia crown was delivered at 4 months postoperation with esthetic outcomes rated highly by both clinician and patient. This case demonstrates that the M-SST, when performed with a standardized shield design, crest-level termination, and digitally guided implant placement, can yield favorable esthetic and functional outcomes. While grafting was selectively applied, the use of minimal intervention and immediate provisionalization contributed to soft tissue preservation. These results support the M-SST as a viable protocol for single-tooth rehabilitation in the esthetic zone.

This study aimed to compare the retention of cobalt-chromium and polyetheretherketone secondary telescopic crowns in implant-retained mandibular overdentures. Twelve patients were selected for the study, each received 2 implants in the canine region bilaterally to retain a mandibular overdenture with milled telescopic crowns. The primary crowns with 2° occlusal taper were fabricated using milled titanium abutments. Later, the patients were randomly divided into 2 groups: the cobalt-chromium group, where the secondary crowns were fabricated from milled cobalt-chromium alloy, and the polyetheretherketone group, where secondary crowns were constructed from milled polyetheretherketone. Retention was evaluated at the relative geometric center at baseline (zero months), 6, 9, and 12 months postprosthetic loading using a force meter gauge. The mean of 5 retention force readings was recorded in Newtons for each patient at follow-up visits, and the data were subject to statistical analysis. At baseline, after 6, 9, and 12 months, the CoCr group showed statistically significantly lower mean retention value than the PEEK group. A statistically significant decrease in retention forces within both groups was observed after 12 months postprosthetic loading. The present study suggested that milled cobalt-chromium and polyetheretherketone secondary telescopic crowns in combination with titanium primary conical crowns may provide an acceptable treatment option for completely edentulous patients regarding retentive force. The milled polyetheretherketone secondary telescopic crowns may offer higher retentive force compared to milled cobalt-chromium ones in clinical performance. To prefer one of these materials over the other needs more extensive research.

The retrieval of a displaced dental implant from the maxillary sinus-whether through an intraoral lateral window or a transnasal endoscopic route-invariably requires further surgical intervention and a subsequent healing period. For instance, in cases where a lateral window approach was not initially indicated, the accidental displacement of a dental implant into the maxillary sinus often necessitates the creation of such an access, which can lead to patient dissatisfaction. If removal through the lateral window proves unsuccessful, referral to an otolaryngologist may become necessary, and a transnasal endoscopic approach must then be employed. These additional procedures inevitably contribute to increased psychological stress for the patient. Furthermore, the waiting period associated with referrals-scheduling consultations with oral and maxillofacial surgeons or ENT specialists, and potential hospital admission-can significantly heighten patient anxiety. The enlargement of the surgical field may also prolong the healing process, particularly osseointegration, potentially delaying treatment completion by 6 months to over 1 year. Additional surgical interventions increase the psychological burden on both the patient and the original surgeon. In this context, the term "original surgeon" refers to the implantologist who initially performed the implant placement and subsequently referred the patient to the authors for management of a displaced implant in the maxillary sinus. Case 1 details the procedural steps undertaken by the authors to retrieve the displaced implant. In Case 2, the implant was inadvertently displaced into the maxillary sinus by the authors themselves during implant placement; it was subsequently retrieved using the technique described in this report. A new implant was immediately placed following removal, and the oroantral communication was successfully prevented. We introduce a simple and reproducible method for clinicians, known as Leon Chen's Modified Valsalva Technique (LCMVT). Leon Chen's Modified Valsalva Technique (LCMVT) involves seating the patient upright with a slight forward tilt, followed by deep inhalation and breath holding. Approximately 8 mL of normal saline is injected into the osteotomy site, after which the clinician occludes the patient's nostrils. The patient is then instructed to exhale forcefully against the closed airway. This maneuver is repeated several times until the displaced implant is mobilized toward the osteotomy opening. This technique significantly reduces the inconvenience of waiting for subsequent surgical interventions and yields positive feedback from patients.

The canalis sinuosis is an anatomical canal located in the anterior maxilla in a minority of patients. It contains a neurovascular bundle that may be encountered during dental implant placement and can be overlooked in radiologic examinations. The neurovascular bundle contains the anterior superior alveolar artery, a branch of the infraorbital nerve, the corresponding vein, and the anterior superior alveolar nerve. Cone-beam computerized tomography (CBCT) may be important in identifying this structure to prevent complications. Complications such as the canalis sinuosis may be confused with pathology without CBCT, leading to an inappropriate diagnosis and subsequent treatment. Thus, it may be erroneously surgically entered to debride a suspected pathology. Therefore, clinicians should understand the canalis sinuosis to avoid potential misadventures.

Dental implants are widely used for treating edentulism, but peri-implant diseases pose a challenge to their success. Excess cement in the gingival sulcus is a significant risk factor for these conditions. Reverse margin abutments have been suggested to minimize excess cement and related risks. This study aims to evaluate the effect of different reverse angles in abutments on reducing excess cement in the gingival sulcus. In this in vitro study, 3 abutments were designed using Solidworks Premium 2023 software: 1 with a chamfer margin and 2 with reverse margins at 30° and 45° angles. Each group consisted of 10 samples (n = 10). The abutments were fabricated using Ti-6Al-4V alloy via 3D printing. Crowns for the maxillary first molar were designed using computer-aided design/computer-aided manufacturing technology and made from zirconia. Thirty fixtures from the Straumann bone-level implant system (GH = 2, diameter 4.5 mm) were mounted in acrylic blocks, and the abutments were positioned on the fixtures. Temp-Bond temporary cement was applied under a pressure of 4 kg. After the cement had set, photographs were taken and analyzed using Adobe Photoshop 2024. The cement extension beyond the margin was quantified in both millimeters and pixels. Data were analyzed using Kruskal-Wallis and Mann-Whitney tests (α = .05). The abutment with a chamfer margin directed the cement toward the apical region, whereas the abutments with reverse margins pushed the cement outside the tissue. The reverse margin abutment with a 30° angle showed a significantly lower excess cement than the chamfer margin abutment (P = .013). Similarly, the reverse margin abutment with a 45° angle had significantly less excess cement than the chamfer margin abutment (P < .001). There was no statistically significant difference between the reverse margin abutments at 30° and 45° angles (P > .05). Using reverse margin abutments instead of chamfer margin abutments significantly reduced the remaining excess cement in the gingival sulcus. However, altering the angle of the reverse margin from 30° to 45° does not significantly impact the overall amount of residual cement.

The purpose of this study was to test the bacterial penetration of screw access holes in monolithic zirconia implant crowns sealed using different methods. Twenty-four monolithic premolar zirconia crowns (IPS e.max ZirCAD) were divided into 4 groups (n = 6) according to the screw access hole filling method: unbonded composite (UBC), bonded composite (BC), airborne-particle abrasion and bonded composite (ABR-BC), and control without a screw access hole. Polytetrafluoroethylene tapes were placed inside the apical parts of the crowns. Crowns were fixed in plastic upper chambers with the occlusal part of the crown being inside the chamber and the apical part outside. A Streptococcus mutans bacterial suspension was poured into the upper chambers. The lower chambers were filled with bacterial culture media up to the apical parts of the crowns. Bacterial penetration through the screw access hole was assessed by visual inspection for turbidity in the lower chamber. The bacterial identity was confirmed on an agar plate culture. The statistical analysis was performed using the Fisher-Freeman-Halton exact test and pairwise comparisons with a z-test. In all test groups, bacterial penetration was observed by the eighth day (1/6 specimens in BC, 3/6 in ABR-BC, and 6/6 in the UBC group). The control group stayed bacteria-free. Bacteria penetrated through the screw access hole of all specimens in the UBC group within 24 hours, which was significantly faster than in other groups (p = .011). Within the limitations of this study, it can be concluded that the sealing method of the screw access hole affects the penetration of S. mutans.

Predicting primary implant stability in fresh extraction sites remains a challenge for clinicians. Accurate forecasting is vital to guide treatment decisions and build strong doctor-patient relationships by clearly communicating success probabilities. This retrospective cohort study evaluates the 5-thread guideline (5-TG), which posits that engaging at least 5 implant threads in native bone ensures high primary stability. Among 150 cases analyzed, the 5-TG demonstrated significant predictive accuracy (p < .0000207), suggesting a reliable framework for assessing stability probabilities: none, low, moderate, or high. The 5-TG is a valuable tool for planning dental implants in newly extracted sites.

This retrospective study evaluates the survival rates, complications, and patient satisfaction associated with zygomatic implants in severe maxillary atrophy, focusing on 2 approaches: Quad Zygoma (4 zygomatic implants) and Hybrid Zygoma (2 zygomatic and 2 standard implants). A total of 76 patients classified as Cawood Grade VI, treated between 2007 and 2021, were included in this study. The primary outcome measure assessed was implant survival rate, while secondary outcomes included complications, patient satisfaction, and willingness to undergo the procedure again. The study included 69 patients with atrophic maxilla and 8 with tumor resection, receiving a total of 262 zygomatic implants, 220 in the Quad Zygoma group and 42 in the Hybrid Zygoma group. The mean follow-up duration was 67.6 ± 49.7 months. Eight implant failures were recorded (3 early and 5 delayed), resulting in an overall survival rate of 96.9%. Biological complications were observed in 27.6% of patients, with sinusitis in 16 patients and soft tissue issues in 5. Technical complications occurred in 6.5% of cases, including screw fractures and loosening of the screws. A patient satisfaction survey of 40 patients indicated high levels of satisfaction, with most expressing a willingness to undergo the procedure again. In conclusion, Zygomatic implants have been shown to have favorable outcomes in patients with severe upper Maxillary atrophies. Both the Quad and Hybrid techniques have shown promising long-term results. However, some complications can occur due to the implants' proximity to important anatomical areas.

This case report illustrates the use of a novel design for a tunneled connective tissue pedicled flap in socket sealing for guided bone regeneration procedures, specifically in the management of compromised sockets. The purpose of this flap is to optimize soft tissue healing and esthetics in these situations, permitting primary closure without buccal flap advancement. Initially, after creating the surgical access with a sulcular and a mesial releasing incision, extraction of the fractured tooth and immediate implant placement were performed. A xenograft and collagen membrane were then placed. Subsequently, a tunnel pedicled connective tissue flap was created on the palate and rotated to the buccal, covering the collagen membrane. This approach avoided the need for an additional distal releasing incision, which may compromise a source of blood supply, thereby decreasing tissue nutrition and potentially resulting in loss of vestibular depth. The tunnel allowed for positioning the pedicled connective graft submucosally, maintaining access to the blood supply via the base. The healing of the soft tissues was uneventful with adequate vascularization and rapid epithelialization. After 3 months, reentry was performed using a circular scalpel, and an implant-supported provisional prosthesis was delivered. After 30 days of tissue conditioning, a ceramic crown was placed over the osseointegrated implant, resulting in a satisfactory esthetic outcome. The new flap design, called the tunneled pedicled connective tissue flap, proved effective for alveolar soft tissue sealing, providing adequate nutrition in guided bone regeneration procedures for compromised sockets. Prospective clinical studies with longer follow-up periods are needed to understand better the potential use of this new flap design for alveolar socket sealing and alveolar ridge preservation procedures on a routine basis.

This case report presents a novel orthodontic technique, orthodontic labial tooth movement for implant site development (OLTM-ISD), for creating adequate horizontal space before immediate implant placement in the esthetic zone. The technique was successfully applied in a 35-year-old male patient with posttraumatic root resorption and partial ankylosis of maxillary central incisors. The patient presented with recurring gingival swelling and invasive cervical resorption in teeth #8 and #9 along with buccal bone wall resorption as Elian type I and II defects, respectively. After surgical luxation of 2 ankylosed teeth, OLTM-ISD was performed using labio-coronal directed forces, achieving both horizontal space creation and vertical soft tissue augmentation. Following orthodontic treatment, immediate implant placement was executed using a fully guided surgical approach with simultaneous buccal bone grafting. After a 3-month healing period, definitive prostheses were delivered. At the 8-month follow-up, the implant-supported prostheses showed harmonious integration with stable peri-implant mucosa, and cone beam computerized tomography imaging confirmed maintenance of labial bone wall thickness exceeding 2.0 mm. This case demonstrates that OLTM-ISD can effectively utilize existing periodontal tissues for site development, particularly in cases with Elian type I or II defects. Whereas these results are promising, further prospective clinical studies are needed to establish standardized protocols and enhance predictability.

The periosteum is a dense connective tissue that envelopes bones It plays an important role in bone regeneration due to its rich cellular composition and vascularity. The periosteum is an autogenous tissue that contains osteoprogenitor cells, which can support osseous regeneration. In oral surgical osseous regeneration, preventing fibroblast infiltration into surgical sites is crucial for successful osseous regeneration. Periosteum successfully excludes fibrous tissue from bone. Utilizing the periosteum as a natural barrier membrane to inhibit fibroblast ingrowth to facilitate optimal bone regeneration adds to the options for the dental surgeon.
