The aim of this study was to evaluate the occurrence and consequences of technical complications in implant-supported restorative therapy.
MATERIAL & METHODS: The occurrence and consequences of technical complications in implant-supported restorative therapy over a mean follow-up period of 5.3 years were assessed based on documentation in files from 2,666 patients. Risk indicators were identified by the use of survival models, considering repeated events. Results were expressed as hazard ratios (HR) including 95% confidence intervals.
Technical complications occurred in 24.8% of the patients. Chipping and loss of retention were the most common, affecting 11.0% and 7.9% of supraconstructions, respectively, while implant-related complications (e.g., implant fracture) were rare. More than 50% of the affected patients experienced technical complications more than once and almost all reported complications led to interventions by a dental professional. The extent of the supraconstruction was the strongest risk indicator for both chipping (HR < 0.2) and loss of retention (HR > 3).
Over a 5-year period, technical complications in implant-supported restorative therapy occurred frequently and their management required professional intervention.
本研究旨在评估种植体支持修复治疗中技术并发症的发生和后果。
基于 2666 名患者的档案记录，评估了种植体支持修复治疗中技术并发症在平均 5.3 年随访期内的发生和后果。使用生存模型确定风险指标，考虑重复事件。结果以包括 95%置信区间的风险比（HR）表示。
24.8%的患者发生了技术并发症。崩瓷和固位丧失最为常见，分别影响了 11.0%和 7.9%的修复体，而与种植体相关的并发症（如种植体骨折）则较为罕见。超过 50%的受影响患者经历了不止一次的技术并发症，几乎所有报告的并发症都需要口腔专业人员进行干预。修复体的范围是崩瓷（HR<0.2）和固位丧失（HR>3）的最强风险指标。
在 5 年期间，种植体支持修复治疗中的技术并发症频繁发生，需要专业干预来处理。
