Introduction: This study aimed to evaluate the efficacy of Biologically oriented Alveolar Ridge Preservation (BARP) in minimizing post‐extraction ridge modifications compared with unassisted socket healing.Methods: A prospective controlled observational study was conducted involving 30 patients requiring single‐rooted upper premolar extractions. Patients were divided into two groups: the test (15 patients), which underwent a ridge preservation procedure combining absorbable collagen sponge in the middle and apical third of the socket and collagenated xenogeneic bone substitute in the most coronal part (BARP), and the control (15 patients), which healed spontaneously. Soft tissue contour changes after 6 months were analyzed using digital impressions. Moreover, histomorphometric analysis of the regenerated tissue was performed in the test group.Results: BARP significantly reduced post‐extractive mucosal ridge modifications compared to the control group. Mean vertical shrinkage at the mid‐buccal part of the edentulous site was 1.61 ± 0.61 mm (BARP) vs. 2.51 ± 0.64 mm (control; t‐test, df = 28, p < 0.001), and mean horizontal reduction was 3.37 ± 0.63 mm (BARP) vs. 4.34 ± 0.48 mm (control; t‐test, df = 28, p < 0.001). Histomorphometric analysis of the regenerated tissue showed 39.7% ± 9.1% newly formed bone with minimal residual graft material (5.0% ± 5.4%).Conclusion: BARP technique effectively minimizes post‐extractive soft tissue contour modifications and supports natural bone regeneration, resulting in adequate bone dimensions for implant rehabilitation.

Background: Plasma surface activation of dental implants has been proposed to enhance osseointegration by improving titanium surface chemistry. However, clinical data in humans remain limited. This randomized controlled trial aimed to assess the effect of vacuum plasma treatment on early implant stability in partially edentulous patients. Materials and Methods: In this single-blind, split-mouth randomized controlled trial, 24 patients requiring two contralateral implants were enrolled. Each patient received one plasma-treated implant and one untreated control implant. Vacuum plasma activation was performed immediately before insertion using a specific system (Plasma X Motion, MegaGen, Gyeongbuk, South Korea). Implant stability was assessed at placement and at 7, 14, 21, 28, 42, 60, and 90 days using resonance frequency analysis (Implant Stability Quotient, ISQ). Results: All 48 implants achieved successful osseointegration at 90 days, with no adverse events or complications. Mean insertion torque did not differ significantly between groups (p = 0.86). Both groups exhibited a typical initial reduction in stability, with the lowest ISQ values at 21 days. Plasma-treated implants showed a more favorable recovery pattern, with significantly higher ISQ values than controls at 60 and 90 days (p = 0.04 and p = 0.03, respectively). Nevertheless, the absolute difference in ISQ values between groups remained limited. Conclusion: Vacuum plasma activation of titanium implants may contribute to a more favorable early stability pattern, although both plasma-treated and untreated implants demonstrated predictable osseointegration outcomes. Further research with larger cohorts and longer follow-up is needed to fully assess the clinical significance of these findings.
