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.
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).
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.
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.
评估中重度牙周炎患者经保守牙周和修复治疗后的长期预后。将比较接受积极牙周治疗（APT）后植入的固定和可摘义齿（FDP、RDP）的年轻（YG）和中年（MG）患者组的存活率。此外，还分析了超过 10 年的辅助牙周治疗（SPT）期间的功能性咬合状态。
本多案例系列回顾性分析了 68 名患者（34 名 YG 和 34 名 MG）的数据，这些患者接受了 APT 和至少 10 年的常规 SPT。通过描述性和比较性（t 检验）评估了失牙、咬合状态以及义齿的存活率和并发症。
YG 和 MG 之间每年的失牙率没有统计学差异（p>0.05）。在 SPT 期间，YG 和 MG 的功能性咬合状态分别保留了 75%和 69%。APT 后植入的修复体在两个年龄组中均显示出高存活率（100%）。YG 中 FDP 和 RDP 的平均存活时间分别为最后一次 SPT 就诊前的 15.2 年和 11.6 年，MG 中分别为 12.5 年和 13.1 年。
如果在进行修复前进行了 APT 和定期的 SPT，严重牙周炎的年轻和中年患者的修复体存活率很高。
