Material and methods Twenty patients were treated with ARP in the compromised extraction sockets by applying CAT. Then implant placement and crown delivery was performed. A planned follow-up was performed by analyzing various outcome measures to evaluate the clinical outcomes, including primary outcome measures [radiographic assessment of residual alveolar ridge height (RARH) and residual alveolar ridge width (RARW)] and secondary outcome measures [clinical assessment of the healing of the soft and hard tissue, survival rates of implants, marginal bone loss (MBL) evaluation of implants, buccal bone thickness (BBT), and esthetic treatment outcomes]. Results Among the 20 patients, 17 were consecutively treated and 3 dropped out after implant crown delivery because of loss to follow-up. After the ARP, the initial RARH (12.37 mm) significantly increased to 19.29 mm (P < .05). No significant difference was detected in the RARW before (7.92 ± 1.18 mm) and after (7.92 ± 1.18 mm) the ARP, but reduce to 6.99 ± 1.18 mm at the implant placement and 6.64 ± 0.77 mm at the 3-year follow-up (P < .05). The MBL at the implant crown delivery (0.13 ± 0.12 mm) significantly increased to 0.31 ± 0.14 mm at 1-year follow-up and 0.56 ± 0.23 mm at 3-year follow-up, respectively. The bone loss was limited (<1 mm) but statistically significant (P < .05). The BBT at the implant placement (2.53 ± 0.56 mm) significantly reduced to 2.23 ± 0.44 mm at implant crown delivery and 2.14 ± 0.40 mm at 3-year follow-up, respectively. The bone loss was als o limited (<0.5 mm) but statistically significant (P < .05). Each implant site showed acceptable aesthetic outcome and the average score was 16.4. The incisions healed uneventful in all patients and the implant survival rate was 100% during the 3-year follow-up. Conclusion Autogenous CAT was successfully applied to preserve the height and width of alveolar ridge in the compromised extraction sockets. View on Web
