Sleep bruxism and higher clench index have been associated with obstructive sleep apnea (OSA). However, there is no study that reports on the prosthetic complications in patients with OSA. Records of patients who had performed a sleep study to diagnose OSA were examined for the occurrence of prosthetic complications in implant-borne reconstructions. The primary outcome was the frequency of prosthetic complications. The secondary outcomes were anthropometric data, type of complication, type of prosthesis, type of retention, number of supporting implants, number of prosthetic units, and the presence of obstructive sleep apnea. Of the 172 patients, 67 had an implant-supported prosthesis, and all were included in the study. The mean age was 61 ± 10 years, and 36 were female. Thirty complications in 22 prostheses were identified in 16 patients. The complications were porcelain fracture (14 events), screw/implant fracture (8 events), screw loosening (3 events), and decementation (5 events). The follow-up time was 117 ± 90 months after placement of the prosthesis. The average time for complications to occur was 73 ± 65 months after the placement of the prosthesis. According to the apnea-hypopnea index (AHI), 49 patients had OSA. Thirteen of the 16 patients having a prosthetic complication also had OSA. The highest AHI and thus the severity of OSA was identified in patients with a fracture complication related to an implant, a screw, or a porcelain. The frequency of prosthetic complications has been higher in patients with obstructive sleep apnea.
睡眠磨牙症和较高的紧咬指数与阻塞性睡眠呼吸暂停（OSA）有关。然而，尚无关于OSA患者修复并发症的研究报告。对进行睡眠研究以诊断OSA的患者记录进行检查，以了解种植体支持的修复体中修复并发症的发生情况。主要结局是修复并发症的发生率。次要结局包括人体测量数据、并发症类型、修复体类型、固位类型、支持种植体数量、修复单位数量以及阻塞性睡眠呼吸暂停的存在情况。在172例患者中，67例有种植体支持的修复体，所有患者均纳入研究。平均年龄为61±10岁，女性36例。16例患者的22个修复体中发现了30处并发症。并发症包括瓷裂（14例）、螺钉/种植体折断（8例）、螺钉松动（3例）和松动（5例）。修复体植入后的随访时间为117±90个月。并发症发生的平均时间为修复体植入后73±65个月。根据呼吸暂停低通气指数（AHI），49例患者患有OSA。16例发生修复并发症的患者中有13例也患有OSA。在与种植体、螺钉或瓷有关的骨折并发症患者中，AHI最高，因此OSA的严重程度也最高。阻塞性睡眠呼吸暂停患者的修复并发症发生率较高。
