To investigate the survival rate of dental implants in patients diagnosed with osteogenesis imperfecta (OI).
The study is a retrospective analysis of six individuals (2 males, 4 females) with OI (type I, III and IV) with a total of 25 dental implants. Clinical examination included plaque index, gingival index, periodontal pocket depth for each implant, presence of pus, and loosening of the implant(s). Marginal bone loss was measured on radiographs. The observation period ranged from 2-17 years (mean:7.5 years, median: 5 years).
The overall implant survival rate was 80%. One patient with OI type III lost five implants. However, four out of five lost implants functioned for 11 years.
Dental implant treatment seems to be a valid option for replacing missing teeth in OI patients. It is recommended that patients diagnosed with OI undergo the same preoperative evaluation as regular dental implant patients with special emphasis on a healthy periodontal status and ideal oral hygiene.
研究成骨不全症（OI）患者牙种植体的存活率。
本研究对6例（2例男性，4例女性）患有OI（I型、III型和IV型）的患者共25颗牙种植体进行回顾性分析。临床检查包括菌斑指数、牙龈指数、每个种植体的牙周袋深度、有无脓液以及种植体松动情况。通过X线片测量边缘骨吸收。观察期为2至17年（平均：7.5年，中位数：5年）。
种植体总体存活率为80%。1例III型OI患者的5颗种植体脱落。然而，5颗脱落种植体中有4颗发挥功能达11年。
牙种植治疗似乎是OI患者缺失牙修复的有效选择。建议诊断为OI的患者接受与常规牙种植患者相同的术前评估，特别强调健康的牙周状况和理想的口腔卫生。
