Using the Roots of a Non Restorable Wisdom Tooth as a Block for Augmentation of Localized Defects

Ain Shams University14 enrolled

Overview

assess and compare the efficacy and safety of autogenous tooth roots for lateral alveolar ridge augmentation with staged implant placement in comparison to autogenous bone block.

A total of 14 patients in need of implant therapy and lateral ridge augmentation were allocated to parallel groups receiving either 1) healthy autogenous tooth roots (e.g. retained wisdom or impacted teeth or 2) cortical autogenous bone blocks harvested from the retromolar area. After 26 weeks of submerged healing the horizontal bone gain were assessed both clinically and radiographically. A core biopsy was taken during the implant placement to assess the histology of the newly formed bone.
