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

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 & 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.
