To investigate the 10-year survival and complication rates of Morse taper connection implants (MTCIs) placed in grafted sinuses.
This study reports on patients treated with maxillary sinus augmentation (with the lateral window technique (LWT) or the transalveolar osteotomy technique (TOT)) and installed with MTCIs supporting fixed restorations (single crowns (SCs) and fixed partial dentures (FPDs)), in two dental clinics. The outcomes of the study were the 10-year implant survival and complication rates.
Sixty-five patients (30 males and 35 females) with a mean age of 62.7 (±10.2) years were installed with 142 MTCIs: 79 fixtures were inserted with the LWT and 63 were placed with the TOT. After ten years, five implants failed, for an overall survival rate of 96.5%. Three implants failed in the LWT group, for a survival rate of 96.3%; two implants failed in the TOT group, for a survival rate of 96.9%. The 10-year incidence of biologic complications was 11.9%. Prosthetic complications were all technical in nature and amounted to 7.6%.
MTCIs seem to represent a successful procedure for the prosthetic restoration of the grafted posterior maxilla, in the long term. This study was registered in the ISRCTN registry with number ISRCTN30772506.
研究植入移植鼻窦的莫氏锥度连接种植体（MTCIs）的10年生存率和并发症发生率。
本研究报告了在两家牙科诊所接受上颌窦提升术（采用侧窗技术（LWT）或经牙槽骨切开术（TOT））并安装支持固定修复体（单冠（SCs）和固定局部义齿（FPDs））的MTCIs的患者情况。研究结果为10年种植体生存率和并发症发生率。
65例患者（30例男性和35例女性），平均年龄62.7（±10.2）岁，共植入142枚MTCIs：79枚种植体采用LWT植入，63枚采用TOT植入。10年后，5枚种植体失败，总生存率为96.5%。LWT组有3枚种植体失败，生存率为96.3%；TOT组有2枚种植体失败，生存率为96.9%。生物并发症的10年发生率为11.9%。修复并发症均为技术性质，发生率为7.6%。
从长期来看，MTCIs似乎是移植后上颌骨修复的一种成功方法。本研究已在ISRCTN注册中心注册，注册号为ISRCTN30772506。
