The aim of this investigation was to retrospectively evaluate the long-term implant loss rates and to identify associations between implant failure and patient-related factors in a sample of patients who had consecutively received implant therapy in ten dental universities in the United States using a large database.
Dental records of adult patients who had attended the dental clinics of the universities contributing data to the BigMouth network between 2011 and 2022 seeking dental therapy were evaluated. Information regarding patients' characteristics including age, gender, ethnicity, race, tobacco use and systemic medical conditions were extracted from patients' files.
A total of 20,842 patients who received 50,333 dental implants over a 12-year period (2011-2022) were included. The mean age of the cohort was 57.50±14.27 years which consisted of 51.8% females, 91.1% non-Hispanic, 66.3% white individuals and 8% tobacco users. In the univariate analysis, ethnicity, race and marijuana use were significantly associated with implant treatment outcome. Race and ethnicity were significantly associated with implant loss in the multivariate analysis. The implant failure rate was estimated to be 2.7% at the patient level and 1.4% at the implant level.
Within the limitations of this retrospective study that utilized records of 50,333 dental implants placed in ten institutions contributing data to the BigMouth network, the implant failure rate was estimated to be 2.7% at patient level and 1.4% at implant level. Ethnicity and race were significantly associated with implant failure, while none of the examined systemic conditions were associated with implant loss.
本研究旨在回顾性评估长期种植体失效率，并在美国十所牙科大学的大样本患者中使用大型数据库，确定种植体失败与患者相关因素之间的关联。
评估了 2011 年至 2022 年间在参与 BigMouth 网络数据的大学牙科诊所接受种植治疗的成年患者的牙科记录。从患者档案中提取了患者特征的信息，包括年龄、性别、种族、民族、吸烟和全身医学状况。
共纳入 20842 名患者，在 12 年期间（2011-2022 年）接受了 50333 个牙种植体。队列的平均年龄为 57.50±14.27 岁，其中 51.8%为女性，91.1%为非西班牙裔，66.3%为白人，8%为吸烟者。单因素分析显示，种族、民族和大麻使用与种植体治疗结果显著相关。多因素分析显示，种族和民族与种植体丢失显著相关。估计患者水平的种植体失败率为 2.7%，种植体水平的种植体失败率为 1.4%。
在这项回顾性研究的限制范围内，该研究利用了向 BigMouth 网络提供数据的十家机构的 50333 个牙种植体记录，估计患者水平的种植体失败率为 2.7%，种植体水平的种植体失败率为 1.4%。种族和民族与种植体失败显著相关，而检查的全身状况均与种植体丢失无关。
