This study investigated the causes of dental implant removal due to complications, and examined whether patients who had dental implant removal desired re-implant prosthesis treatments.
A retrospective case-control study was conducted on patients who had their dental implants removed. We investigated whether the removed dental implant was replaced with other implant prostheses. Age, sex, diabetes, smoking, implant site distribution, reason for implant removal, and blade and root-form implants were categorized as predictive variables. The outcome variable was desire for re-implantation or use of other prosthetic methods after implant removal. A logistic regression model was created to identify patient factors that could predict the re-implantation of dental prostheses after implant removal.
A total of 215 dental implants were removed from 143 patients. The most common reason for implant removal was peri-implantitis that was identified in 165 implants. After implant removal, re-implantation was performed in 98 implants (45.6%). Bivariate analyses showed that age, diabetes, implant type, and reason for implant removal were associated with the desire for re-implanted prostheses. The multiple regression model revealed that age, implant type, and reason for implant removal were associated with an increased desire for re-implant prostheses after implant removal.
Re-implantation of prostheses after the removal of dental implants was desired by patients who were younger, had implants placed in the root form, and had implants removed due to prosthetic-related complications.
本研究调查了因并发症而拔除种植体的原因，并探讨了拔除种植体的患者是否希望接受再次种植修复治疗。
对接受种植体拔除的患者进行回顾性病例对照研究。我们调查了是否用其他种植体修复体代替了已拔除的种植体。将年龄、性别、糖尿病、吸烟、种植体部位分布、种植体拔除原因、叶片形和根形种植体归类为预测变量。结果变量为种植体拔除后是否希望再次种植或使用其他修复方法。建立逻辑回归模型以确定患者因素，这些因素可以预测种植体拔除后再次种植修复体的可能性。
从 143 名患者中总共取出 215 个种植体。最常见的种植体拔除原因是种植体周围炎，共 165 个种植体。种植体拔除后，有 98 个种植体（45.6%）进行了再次种植。单变量分析显示，年龄、糖尿病、种植体类型和种植体拔除原因与再次种植修复体的愿望有关。多元回归模型显示，年龄、种植体类型和种植体拔除原因与种植体拔除后再次种植修复体的愿望增加有关。
对于年龄较小、采用根形种植体且因修复相关并发症而拔除种植体的患者，他们希望在拔除种植体后再次植入修复体。
