Alveolar Ridge Augmentation

CGF membranes will be prepared using a swing-lock centrifuge. A full-thickness mucoperiosteal flap will be elevated in a narrow alveolar ridge. Implants will be inserted. Autologous bone chips will be harvested via bone scraping and used for augmentation, CGF membranes will be placed over the grafted area. Suturing of the mucoperiosteal flap. Radiographic evaluation of the bone density and tissue thickness will be performed by CBCT preoperatively, immediate postoperative and after the procedure by 4 months. Clinical evaluation of the tissue thickness using periodontal probe preoperatively, immediate postoperatively and after the procedure by 4 months

This research aims to compare the effectiveness of two bone grafting materials on preserving jawbone integrity after tooth extraction. Following extraction, the jawbone surrounding the removed tooth can shrink, affecting future implant placement. By placing a bone graft material in the extraction socket, we aim to maintain adequate jawbone space for future implants. This study compares how well the mixture of vallos®f (human source bone) and Bio-Oss (animal source bone) \[test\], and vallos® only \[control\] grafting materials work. Participants with at least one tooth planned for extraction and subsequent implant placement are sought for this study. Participants will be randomly assigned to either the mixture of vallos®f and Bio-Oss (test) group or the vallos® only (control) group. Throughout the approximately 2-year study duration, participants will undergo oral exams, x-rays, surgical procedures, and follow-up visits. All participants will undergo routine tooth extraction, bone graft material placement, and dental implant placement. After the crown is placed on the implant, participants will attend follow-up visits. Participation in the study is voluntary, and the alternative is to continue routine dental care. Risks include minor discomfort from procedures such as tooth extraction and implant placement. The major benefit of participation in the study is the preservation of jaw dimensions following extraction, which will simplify the placement of a dental implant.

Socket preservation procedures after tooth extraction have been designed and implemented to maintain the volume of the bone and gingival tissues, which can decrease following the extraction of the teeth. In this clinical trial we will compare clinically and histologically the effectiveness of two distinct bovine bone graft materials; an allograft and a xenograft, in alveolar ridge preservation procedures following tooth extraction .

Tooth extraction sites often require alveolar bone grafting to preserve ridge dimensions and improve conditions for future implant placement. Although systemic antibiotic prophylaxis is commonly prescribed after grafting procedures, there is limited evidence supporting its necessity in healthy patients undergoing intraoral bone grafting. This randomized, double-blind, placebo-controlled clinical trial aims to compare the effects of prophylactic amoxicillin versus placebo on postoperative outcomes in alveolar bone graft procedures using Plenum® Oss HP biomaterial, a synthetic biphasic bioceramic composed of hydroxyapatite and beta-tricalcium phosphate (HA/β-TCP; 70:30 ratio). Participants will be randomly assigned to receive either amoxicillin 500 mg every 8 hours for 7 days or a matching placebo. Clinical parameters, postoperative complications, and patient-reported outcomes will be assessed. The study seeks to determine whether antibiotic prophylaxis provides measurable clinical benefits or whether placebo yields comparable results, contributing to more rational antibiotic use and supporting antimicrobial stewardship in oral surgery.

This clinical trial aims to compare the efficacy and safety of applying "PeptiCol EZgraft" in extraction socket preservation procedures against "Regenomer," in terms of reducing the amount of alveolar bone change during the healing process following tooth extraction.
