To analyze the prognostic factors that are associated with the success, survival, and failure rates of dental implants.
Data including implant sizes, insertion time, implant location, and prosthetic treatment of 1656 implants have been collected, and the association of these factors with success, survival, and failure of implants was analyzed.
The success rate was lower for short and maxillary implants. The failure rate of maxillary implants exceeded that of mandibular implants, and the failure rate of implants that were placed in the maxillary anterior region was significantly higher than other regions. The failure rates of implants that were placed 5 years ago or more were higher than those that were placed later.
Anterior maxilla is more critical for implant loss than other sites. Implants in the anterior mandible show better success compared with other locations, and longer implants show better success rates. The learning curve of the clinician influences survival and success rates of dental implants.
分析与牙种植体的成功率、存留率及失败率相关的预后因素。
收集了1656颗种植体的相关数据，包括种植体尺寸、植入时间、种植体位置及修复治疗情况，并分析了这些因素与种植体成功、存留及失败的相关性。
短种植体及上颌种植体的成功率较低。上颌种植体的失败率超过下颌种植体，且位于上颌前部区域的种植体失败率显著高于其他区域。5年或更早植入的种植体失败率高于后期植入的种植体。
上颌前部区域对于种植体丧失比其他部位更为关键。下颌前部的种植体相比其他部位成功率更高，且较长的种植体成功率更高。临床医生的学习曲线会影响牙种植体的存留率和成功率。
