Bone Grafting Materials Used in treatment of Periodontal Intrabony and Furcation Defects: A Systematic Review of Clinical, Radiographic, and Patient-Centered Outcomes

Comparative Effectiveness of Vertical Ridge Augmentation Techniques for Dental Implant Treatment: A Systematic Review

While DO provides the greatest vertical bone gain, the GBR techniques might be a more clinically practical option, however, future well-planned RCTs to identify effective vertical bone augmentation techniques are still warranted.

Short Dental Implants (≤6 mm) for Posterior Edentulism: A Comprehensive Review of Survival Rates and Complications

Background: Short dental implants (≤6 mm) are increasingly used for posterior rehabilitation in patients with limited alveolar bone height. This review examines their survival rates, marginal bone loss (MBL), peri-implantitis, and technical/prosthetic complications compared with standard-length implants. Methods: A narrative review of the literature was conducted using PubMed, Scopus, and Cochrane Library databases. Search terms included 'short dental implants', 'posterior edentulism', 'survival rates', 'marginal bone loss', 'peri-implantitis', and 'bone augmentation'. Randomized controlled trials (RCTs), systematic reviews, meta-analyses, and prospective and retrospective clinical studies published between 2018 and 2024 were included. Studies were selected based on implant intrabony length of ≤6 mm, a minimum follow-up of 12 months, and reporting of at least one primary outcome. Results: Evidence from a meta-analysis of 16 RCTs (408 short implants; 475 standard-length implants) demonstrates statistically higher survival rates for longer implants (99.4% vs. 95.1%; 95% CI: 2–5%, p < 0.001), though no significant difference was found in early or late implant failure rates. MBL was marginally but non-significantly lower for short implants (0.23 mm vs. 0.27 mm). Peri-implantitis prevalence (0–6% vs. 0–13%) and technical/prosthetic complication rates were comparable between groups. Crown-to-implant ratios of 1.55–1.86 in short implants did not translate to elevated complication rates when prostheses were splinted. A systematic review and meta-analysis of 13 RCTs confirmed equivalent survival at all follow-up intervals without the need for bone augmentation. Conclusions: Short dental implants represent a valid, minimally invasive alternative to bone augmentation in appropriately selected patients. Optimal outcomes depend on modern nano-structured implant surfaces, adequate prosthetic splinting, bone quality assessment, and rigorous peri-implant maintenance. Further long-term RCTs with standardized peri-implantitis criteria are needed.

Clinical and radiographic outcomes of bone lid technique in endodontic microsurgery: A retrospective study.

INTRODUCTION To compare the clinical and radiographic outcomes of the bone lid technique and conventional osteotomy in endodontic microsurgery (EMS) for teeth with an intact labial or buccal plate of bone (≥1 mm). METHODS This retrospective study included 64 teeth from 64 patients who underwent EMS between January 2021 and July 2025. Cases were assigned to the bone lid (BL) group or conventional osteotomy (CO) group according to the surgical approach. Cone-beam computed tomography data were evaluated at baseline and at 3, 6, and 12-24 months after surgery. The primary outcome was comprehensive success, defined as both clinical and radiographic success at 6 and 12-24 months. Secondary outcomes included clinical success, radiographic success, lesion volume reduction, grayscale value changes, buccal plate of bone thickness, and alveolar arch contour. Regression models were used to identify outcome-associated factors. RESULTS The BL group achieved greater lesion volume reduction and better preservation of buccal plate of bone thickness at both intervals (P< 0.05). Alveolar arch collapse was less frequent in the BL group at 6 months (6.3% vs. 73.1%,P< 0.05) and 12-24 months (0.0% vs. 26.3%,P< 0.05). Clinical success (asymptomatic healing) was comparable between groups at all time points (e.g., T3: 100.0% in BL vs. 77.3% in CO,P> 0.05). However, the BL group showed significantly higher radiographic complete healing rates at T2 (80.0% vs. 30.3%,P< 0.05) and T3 (100.0% vs. 59.1%,P< 0.05), as well as higher comprehensive success at T2 (90.0% vs. 54.5%,P< 0.05) and T3 (100.0% vs. 68.2%,P< 0.05). CONCLUSIONS For teeth with a preoperative buccal plate of bone ≥1 mm, the bone lid technique provided more favorable radiographic healing and better preserved alveolar arch contour than conventional osteotomy.

Factors Related to the Outcomes of Secondary Alveolar Cleft Bone Grafting Using Two-Dimensional Radiographic Analysis: A Retrospective Study.

BackgroundSecondary alveolar bone grafting (SABG) is essential for correcting alveolar defects in patients with cleft lip and palate. While clinical evaluation combined with 2-dimensional (2D) radiography is a practical and cost-effective method for assessing surgical success, inadequate grafting outcomes often necessitate repeat surgeries.ObjectiveTo evaluate the clinical variables influencing SABG outcomes in cleft patients using 2D radiographic images.Materials and MethodsThis retrospective study reviewed data from 63 patients who underwent SABG at the Faculty of Dentistry, Prince of Songkla university between 2013 and 2023. Variables analyzed included age, cleft type/size, surgical techniques, graft materials, and orthodontic timing. Efficacy was assessed via 2D radiographs (18 conventional, 45 digital) using the Chelsea scale for bone bridging and ImageJ software for bone density. Statistical analyses involved Chi-square tests and multiple logistic regression (P < 0.05).ResultsOverall analysis revealed that patient age and cleft type were the only significant predictors of SABG success, with odds ratios of 10.46 and 5.19, respectively. Subgroup analyses indicated that the timing of post-surgical orthodontic movement was the most significant factor in the conventional radiography group, whereas cleft type was the primary determinant in the digital group.ConclusionPatient age and cleft type significantly impact SABG outcomes. Patients aged 10-12 years and those with unilateral cleft deformities exhibit significantly higher success rates compared to other age groups and bilateral deformities.

Clinical outcomes of intrabony defects treated with bone graft and collagen membrane using apically incised coronally advanced surgical technique or papilla preservation technique: a randomized controlled trial

Clinical and radiographic performance of implant restorations with different angulated screw channel abutments in the esthetic area: A retrospective exploratory cohort study with a mean follow-up of 24 months.

OBJECTIVES To evaluate the clinical and radiographic outcomes of implant restorations with two different angulated screw channel abutments in the esthetic area. MATERIALS AND METHODS Patients with implant restorations using angulated screw channel abutments (AS or ASC group) were encompassed. Sixty-seven restorations (34 in AS and 33 in ASC) in 54 patients (27 in AS and 27 in ASC) were analyzed. Survival rates, mechanical complications, and biological parameters were recorded. Esthetic outcomes were assessed using the Pink and White Esthetic Score (PES/WES) and patient satisfaction via Visual Analog Scale (VAS). Radiographic analysis evaluated marginal bone loss (MBL), buccal bone thickness (BBT), and prosthesis design. RESULTS No implant loss occurred during a mean follow-up of 23.79 ± 7.63 months. The AS group showed severe mechanical complications requiring remaking (11.8% vs. 0%) and a numerically higher mechanical complication rate (26.5% vs. 15.2%); however, neither difference was statistically significant (P > 0.05). The AS group also had significantly greater PD (P = 0.041) and BOP% (P = 0.047). Both groups achieved favorable esthetics and satisfaction. CONCLUSIONS Both abutment types are feasible for the anterior maxilla, providing good esthetics, satisfaction, and bone stability. The AS group experienced severe mechanical complications, which may warrant closer clinical attention. CLINICAL SIGNIFICANCE The ASC abutment showed favorable numeric trends in mechanical complications and peri‑implant soft tissue health. If using the AS abutment, closer attention to the restoration's cervical region is advised from our observations.
