Objectives: Long-term outcomes of conservative periodontal and prosthetic treatment of patients with moderate to severe periodontitis were to be evaluated. Groups of younger (YG) and middle-aged patients (MG) were to be compared regarding survival of fixed and removable dental prostheses (FDP, RDP) inserted after active periodontal therapy (APT). In addition, functional-occlusal status over more than 10 years of supportive periodontal therapy (SPT) was analysed.
Methods: The present multi-case-series retrospectively analysed data of 68 patients (34 YG and 34 MG) who had received APT and regular SPT ≥10 years. Tooth loss, occlusal status and survival and complications of prosthetics were evaluated descriptively and comparatively (t-test).
Results: There was no statistical difference between YG and MG concerning tooth loss/year (p > 0.05). Functional-occlusal status was retained during SPT in 75% and 69% of YG and MG. Restorations inserted after APT showed high survival for both age groups (100%). Mean survival time until the last SPT visit was 15.2 and 11.6 years for FDP and RDP in YG, and 12.5 and 13.1 years in MG.
Conclusions: Prosthetic restorations in both younger and middle-aged patients with severe periodontitis showed high survival, if pre-prosthetic APT and regular SPT had been performed.
