Titanium-platelet rich fibrin (T-PRF) is an autologous biomaterial, and when used with bone graft it could enhance the bone regeneration. Hence, the aim of this study was to evaluate the combined effect of T-PRF with nanocrystalline hydroxyapatite (Nano-HA) and T-PRF with demineralized bone matrix (DMBM).</p><p><strong>Materials and methods: </strong>Twenty systemically healthy patients were included in the study and were randomly assigned into two groups. Ten patients were treated with atraumatic extraction followed by ridge preservation using Nano-HA bone graft and T-PRF. In another group of ten patients, ridge preservation was done using a xenograft-DMBM. Preoperative cone beam computed tomography (CBCT) and postoperative CBCT after 3 months were evaluated for bone fill. The clinical parameters of ridge width (RW) and ridge height were measured clinically, with the help of UNC 15 probe, after 3 months.</p><p><strong>Results: </strong>The treatment modality resulted in significant bone fill in CBCT and adequate RW clinically in both the groups. The mean bone density in the Nano-HA + T-PRF group was recorded as 776.72 ± 223.94, and 854.72 ± 183.57 was observed in the DMBM + T-PRF group, after 14-16 weeks.</p><p><strong>Conclusion: </strong>The study's findings indicate that ridge preservation performed at the time of extraction is a reliable and predictable approach for minimizing alveolar bone resorption. Additionally, the combination of T-PRF with bone grafts yields effective results in a relatively short timeframe.</p><p><strong>Clinical significance: </strong>This technique involves combining osteoconductive material from Nano-HA and DMBM and the growth factor-rich matrix of T PRF for quicker healing and better esthetic and functional results. It reduces morbidity in patients, does not require an autogenous graft, is biocompatible, and is economical; therefore, both clinical practice and regenerative research in the field of dentistry are advanced. Hence, it is one of the important evidences through this original study.

In the second group (implant-cantilever metal ceramic group), we treated nine participants by placing single implant with cantilever metal ceramic fixed dental prosthesis (FDP). In the third group (implant-cantilever PEEK group), we treated nine cases utilizing single implant with a cantilever PEEK FDP framework. Clinical and radiographic examinations were recorded. Marginal bone level, implant stability, and prosthetic complications were assessed during an 18-month follow-up period.</p><p><strong>Results: </strong>Marginal bone loss (MBL) exhibited similar measurements among all groups. The clinical outcomes did not address significant variance among all groups as regards implant stability within the period of follow-up. We also observed minor prosthetic complications. Participants were very satisfied within all groups.</p><p><strong>Conclusion: </strong>Based on the limitations of our research, utilizing cantilever extensions has no influence on MBL as well as implant stability.</p><p><strong>Clinical significance: </strong>Mean marginal bone level exhibited a significant rise from baseline to 18 months for all groups, however, still within the clinically accepted range. Regarding implant stability, no significant variance was observed among all groups for 18 months. The cantilever FDP design facilitated prosthesis fabrication among those having laterals of narrow diameters. Further research is required to investigate such a particular concern due to a limited sample size in our research.
