The goal of the study was to evaluate marginal bone loss (MBL) after 1-year implant placement using a guided implant surgical (GIS) protocol in grafted sockets compared to non-grafted sites. We followed a parallel study design with patients divided into two groups: grafted group (Test group, n = 10) and non-grafted group (Control, n = 10). A bioactive glass bone graft was used for grafting. A single edentulous site with a minimum bone height ≥11 mm and bone width ≥6 mm confirmed by cone-beam computerized tomography (CBCT) was chosen for implant placement. Tapered hybrid implants that were sandblasted and acid-etched (HSA) were placed using the GIS protocol and immediately loaded with a provisional prosthesis. MBL and implant survival rates (ISR) were assessed based on standardized radiographs and clinical exams. Patients were followed up for 1-year post-loading. MBL after one year, in the control group, was −0.31 ± 0.11 mm (mesial) and −0.28 ± 0.09 mm (distal); and in the test group was −0.35 ± 0.11 mm (mesial) and −0.33 ± 0.13 mm (distal), with no statistical significance (p > 0.05). ISR was 100% in both groups after one year. ISR was similar between groups and the marginal bone changes were comparable one year after functional loading, without statistical significance, suggesting that bioactive glass permitted adequate bone formation. The GIS protocol avoided raising flaps and provided a better position to place implants, preserving the marginal bone around implants.

Background and objectives: The study aimed to evaluate and compare the amount of papillary gain and black triangle height reduction after intervention with a microtunnelling technique with either Connective tissue graft (CTG) or Platelet-rich fibrin (PRF) as a biomatrix at 6 months using a microsurgical approach. Materials and Methods: Twenty-six patients with interdental papillary loss were included in the study. The patients were selected randomly for the study groups with thirteen patients in each group: a control group where CTG was utilised as a matrix, and a test group where PRF was utilised as a matrix, for interdental papillary reconstruction. A microtunnelling technique was performed for both the study groups under a surgical microscope. The primary parameters assessed were interdental Papillary height (PH) and Black triangle height (BTH) at baseline, with secondary parameters Visual analogue score by dentist (VAS-D) and patient (VAS-P) assessed at 6 months. Results: Both the control and test groups showed a significant reduction in BTH within their respective group at six months (p < 0.05). The gain in papillary height significantly improved only in the CTG group at 6 months. However, significant differences could not be demonstrated for any of the variables such as BTH (p value = 0.582) and PH (p-value = 0.892) between the study groups at 6 months. Conclusions: IDP reconstruction utilising a microtunnelling approach with CTG or PRF was successful without any significant differences between the groups for the parameters assessed at 6 months.

Purpose: The study aimed to compare clinical and radiographic parameters of peri-implant site of laser-microgrooved implants with either laser-microgrooved or regular machined prosthetic abutment post 3 years of early loading.Method: Twenty edentulous sites of systemically and periodontally healthy individuals were allocated into two groups in this prospective, two-armed, randomized double-blinded clinical trial in 1:1 ratio, wherein each site received laser-microgrooved implants with either laser-microgrooved or machined prosthetic abutments. Outcome measures included full-mouth plaque (FMPS%) and bleeding score (FMBS%), site-specific plaque (SPS%) and bleeding score (SBS%), peri-implant sulcus depth (PISD mm), and mean crestal bone loss (MCBL mm) evaluated at baseline (6 weeks), 1 and 3 years post-early loading. Mean and standard deviation of all parameters were estimated, between groups and at different time points using independent and pairedt-test, respectively, Normality was checked using Kolmogorov–Smirnov test and Shapiro–Wilk test,Pvalue ≤ 0.05 was considered as statistically significant.Results: Three-year follow-up of test group showed statistically significant reduction in SPS, SBS, PISD (Pvalue ≤ 0.001). The MCBL reduced from 1.93 mm to 0.61 mm (Pvalue ≤ 0.001); in other words, a bone gain of 0.15 mm was obtained in the test group.Conclusion: Within the limitations of the present study, laser-microgrooved implants loaded with laser-microgrooved prosthetic abutments showed superior results clinically and radiographically when compared to loading with machined abutments.

Purpose: To evaluate the efficacy of two hydrodynamic sinus lifting procedures and to successfully place immediate implants in maxillary posterior sites that have a compromised native bone as a result of periodontal or endodontic disease. Patients and Methods: A total of 26 patient sites were enrolled with 13 sites each in the Minimally Invasive Antral Membrane Balloon Elevation (MIAMBE) and Drill Integrated Hydrodynamics for the transcrestal sinus floor elevation (DIHSFE) groups who received transcrestal sinus floor elevation followed by immediate implant placement. Clinical parameters such as sinus membrane perforations, nasal bleeding, postoperative sinusitis, VAS scores at Day-7 for pain and discomfort, primary implant stability and time taken were evaluated. Results: The DIHSFE had greater sinus membrane perforations and incidence of nasal bleeding when compared with MIAMBE with (p = 0.066) and (p = 0.141). Post-operative sinusitis was evident in both the groups with (p = 0.619). The mean VAS score was statistically significant between both the groups (p ≤ 0.005). The insertion torque values, and mean time taken for surgical procedure was not statistically significant between groups. Conclusion: The present study highlighted that MIAMBE is superior to DIHSFE in its ability to cause less severe patient morbidities and post-operative complications.

Background: Dental root coverage, crucial in managing gingival recessions, traditionally utilizes subepithelial connective tissue grafts. However, this approach has limitations such as donor site morbidity and graft availability. Recent studies have introduced platelet-rich fibrin (PRF) as an alternative, leveraging its regenerative potential and growth factors. Despite the promise, comparative assessments between PRF and conventional grafts remain limited. This research probes whether PRF, when used beneath a modified Ruben's mixed flap, could provide comparable or superior dental root coverage than a subepithelial connective tissue graft. Material/Methods: We enrolled 30 patients exhibiting Miller's class I and II recession in this comparative case series. Patients were randomly assigned to receive either a connective tissue graft (15 patients) or a PRF matrix (15 patients), both covered by a modified Ruben's mixed flap.Results: Clinical parameters, including full mouth plaque scores, bleeding scores, probing sulcus depth, clinical attachment level, gingival position assessment, width, and thickness of attached gingiva, were assessed in both the control and test groups at baseline, 6 months, and 12 months post-surgery. Significant differences were observed at all intervals. At the 12-month mark, the control group (connective tissue graft) achieved 91% complete root coverage, while the test group (PRF matrix) achieved 86%. However, this difference was not statistically significant.Conclusions: The study outcomes suggest comparable gains in root coverage and attached gingiva between the connective tissue graft and PRF matrix groups. Thus, the results support our hypothesis that a subepithelial PRF matrix can serve as a viable alternative to a subepithelial connective tissue graft for treating dental root coverage.
