种植体早期失败的相关因素分析

Abstract

Abstract: Objective To explore the influencing factors related to early implant failure based on the retrospective analysis of the implant data of the Stomatological Hospital Affiliated to Zhejiang University School of Medicine in 2018. Methods The data and implant situation of patients who received implant surgeries at the Affiliated Stomatology Hospital of Zhejiang University School of Medicine were collected during January to December in 2018. The factors influencing the early implant failure were analyzed from the patients’ own factors, implant factors, and additional bone incremental surgical factors. Results A total of 3504 patients received 6,178 dental implants in 2018, including 1,626 males and 1,878 females. Up to August 31, 2019, a total of 46 patients (47 implants) of early failures were clearly recorded. The early failure rate was 1.31% (46/3504) at the patient level, and 0.76% (47/6178) at the implant level. The early implant failure rate of male patients was significantly higher than that of female patients, which was statistically significant (P <0.05). The early implant failure rate of the implants with a diameter ≤3.5mm was 1.2% (22/1829), which was significantly higher than that of implants with a diameter of 3.6mm-4.5mm (P <0.05). A total of 419 ZDI implants were placed in 2018, and there were 11 implant failures at the early stage. The early implant failure rate was 2.63%, which was statistically higher than that of other implant systems such as Nobel and Straumann, and the difference was statistically significant (P <0.01). Conclusion Male patients are more likely to have early implant failures, and the implant with a diameter ≤ 3.5mm, mandibular anterior teeth and ZDI implants have higher early failure rates.

Key words: implantation, early failure, early implant failure rates
