TR may serve as an alternative graft to support lateral alveolar ridge augmentation and two-stage implant placement.

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.

The onset, progression and resolution of experimental peri-implant mucositis lesions were comparable in both groups.
