Int J Prosthodont. 2016 May-Jun;29(3):296-8. doi: 10.11607/ijp.4610.
PURPOSE
Ceramic veneer fracture is a frequent complication in implant-borne fixed restorations. The retrospective clinical study assesses the effect of bruxism on this complication.
MATERIALS AND METHODS
A sample of 507 implant-borne fixed units inserted between 1995 and 2011 in 144 patients were examined. Any detected veneer fractures were assigned to one of four groups according to extent and position. A hypothetical correlation between bruxism and ceramic veneer fractures was examined.
RESULTS
Of 34 patients (23.6%) with at least one ceramic veneer fracture, 24 were bruxers (70%) and 10 were nonbruxers (30%) (P = .002).
CONCLUSION
Bruxism may pose a risk for ceramic fractures.
目的
陶瓷贴面裂是种植体支持的固定修复体中常见的并发症。本回顾性临床研究评估磨牙症对此并发症的影响。
材料和方法
对 1995 年至 2011 年间在 144 名患者中植入的 507 个种植体支持的固定单位进行了检查。根据范围和位置，任何检测到的贴面裂都被分配到四个组之一。磨牙症与陶瓷贴面裂之间的假设相关性进行了检查。
结果
在至少有一个陶瓷贴面裂的 34 名患者中，24 名是磨牙症患者（70%），10 名是非磨牙症患者（30%）（P =.002）。
结论
磨牙症可能是陶瓷裂的一个危险因素。
