Short-term outcomes of staged lateral alveolar ridge augmentation using autogenous tooth roots. A prospective controlled clinical study.

OBJECTIVES: To assess the short-term clinical outcomes of lateral alveolar ridge augmentation using autogenous tooth roots (TR) and autogenous bone blocks (AB). MATERIAL AND METHODS: A total of n = 23 patients (23 implants) were available for the analysis. Each subject was allocated to lateral ridge augmentation using either (a) healthy autogenous tooth roots (e.g., retained wisdom or impacted teeth; n = 13) or (b) cortical autogenous bone blocks harvested from the retromolar area (n = 10). 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: TR and AB groups were associated with comparable (p > 0.05) changes in mean BOP (-23.0 +/- 34.3%; -11.75 +/- 24.9%), PD (-0.03 +/- 0.14 mm; -0.1 +/- 0.29 mm), MR (0.0 +/- 0.0 mm; 0.0 +/- 0.0 mm) and CAL (-0.03 +/- 0.14 mm; -0.1 +/- 0.29 mm) values. The regression analysis failed to reveal any significant correlations between changes in BOP and PD values and the initial as well as the ridge width measured at 26 weeks. CONCLUSIONS: TR and AB were associated with comparable clinical short-term outcomes.
