Short-term outcomes of lateral extraction socket augmentation using autogenous tooth roots: A prospective observational study

Abstract

Objectives: To assess the short-term clinical outcomes of lateral augmentation of deficient extraction sockets and two-stage implant placement using autogenous tooth roots (TR). Material and methods: A total of n = 13 patients (13 implants) were available for the analysis. At the time of tooth extraction, each subject had received lateral augmentation using the respective non-retainable but non-infected tooth root where the thickness of the buccal bone was <0.5 mm or where a buccal dehiscence-type defect was present. Titanium implants were placed after a submerged healing period of 6 months and loaded after 20 ± 2 weeks (V8). Clinical parameters (e.g., bleeding on probing—BOP, probing pocket depth—PD, mucosal recession—MR, clinical attachment level—CAL) were recorded at V8 and after 26 ± 4 weeks (V9) of implant loading. Results: At V9, all patients investigated revealed non-significant changes in mean BOP (−19.23 ± 35.32%), PD (0.24 ± 0.49 mm), MR (0.0 ± 0.0 mm) and CAL (0.24 ± 0.49 mm) values, respectively. There was no significant correlation between the initial gain in ridge width and changes in BOP and PD values. Conclusions: The surgical procedure was associated with stable peri-implant tissues on the short-term.
