This retrospective cohort study reviewed dental implant treatment completed at the Adelaide Dental Hospital over a 20-year period.
The database of implant treatment completed between 1996 and 2015 was analysed for patient, implant, prosthesis and operator specifics together with known implant status.
Three hundred and twenty patients (mean age, 51.50 years) were treated with 527 implants. One hundred and eighty-four female patients received 296 implants and 136 males received 231 implants. Three hundred implants were restored with single crowns, 147 implants were restored with 63 mandibular implant overdentures, five implants were restored with two maxillary implant overdentures and 67 implants were restored with 20 full-arch fixed prostheses. The overall known implant survival rate was 87.67%. Mandibular implant overdentures had a risk of implant failure four times that of single implant-retained crowns that was statistically significant (P = 0.0100).
Implant treatment completed in this public sector clinic using finite resources and a defined system of patient and restorative selection criteria demonstrated a high known implant survival rate. Utilizing a structured and maintained patient recall protocol, it would be ideal to investigate further parameters of interest, particularly those that could improve treatment delivery and longevity.
本回顾性队列研究分析了阿德莱德牙科医院在 20 年期间完成的牙种植体治疗。
对 1996 年至 2015 年间完成的种植体治疗的数据库进行了分析，包括患者、种植体、修复体和操作人员的具体情况以及已知的种植体状况。
320 名患者（平均年龄 51.50 岁）接受了 527 个种植体治疗。184 名女性患者接受了 296 个种植体，136 名男性患者接受了 231 个种植体。300 个种植体采用单冠修复，147 个种植体采用 63 个下颌种植体覆盖义齿修复，5 个种植体采用 2 个上颌种植体覆盖义齿修复，67 个种植体采用 20 个全口固定义齿修复。总的已知种植体存活率为 87.67%。下颌种植体覆盖义齿的种植体失败风险是单种植体保留冠的四倍，具有统计学意义（P = 0.0100）。
在这个公共部门诊所，使用有限的资源和明确的患者和修复体选择标准完成的种植体治疗显示出较高的已知种植体存活率。利用结构化和维护的患者召回方案，理想情况下可以进一步研究感兴趣的参数，特别是那些可以提高治疗效果和延长寿命的参数。
