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

Abstract

To assess the short-term clinical outcomes of lateral augmentation of deficient extraction sockets and two-stage implant placement using autogenous tooth roots (TR). 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 <0.5mm or where a buccal dehiscence-type defect was present. Titanium implants were placed after a submerged healing period of 6months and loaded after 20±2weeks (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±4weeks (V9) of implant loading. At V9, all patients investigated revealed non-significant changes in mean BOP (-19.23±35.32%), PD (0.24±0.49mm), MR (0.0±0.0mm) and CAL (0.24±0.49mm) values, respectively. There was no significant correlation between the initial gain in ridge width and changes in BOP and PD values. The surgical procedure was associated with stable peri-implant tissues on the short-term.
