About

The aim of the study is to examine potential influencing factors on the changes in the periodontal parameters probing pocket depth (PPD), bleeding on probing (BOP), and alveolar bone loss (ABL) on implants and control teeth (using a split-mouth design) over five (T-5), 7.5 (T-7), and ten years (T-10) of supportive periodontal care (SPC). For this purpose, 150 patients with periodontitis and implants are re-examined cross-sectionally (T0), and the changes in the main peri-implant and periodontal target parameters are compared retrospectively at the specified observation time points (T-5, T-7, T-10).

Potential influencing factors to peri-implant conditions include patient-related factors, therapy-related factors and implant-related factors. In addition, patients will be surveyed using validated questionnaires on oral health-related quality of life (OHIP-G14), and a number of common risk factors for periodontits and peri-implant conditions.
