| Study type | Observational |
The goal of this observational study is to compare the prevalence of peri-implantitis between periodontitis and nonperiodontitis sites treated with alveolar ridge preservation. The main question it aims to answer is: • whether the occurrence of PI is associated with reasons for dental extraction because of periodontitis and nonperiodontitis after alveolar ridge preservation. Researchers will compare the prevalence of peri-implantitis between periodontitis and nonperiodontitis sites treated with alveolar ridge preservation.
