The purpose of this study was to evaluate the clinical, radiographic, and patient-based outcomes of dental implants placed at an undergraduate student dental clinic.
A retrospective study was performed to determine the success and survival rates of dental implants placed at the undergraduate dental clinic at Dalhousie University between January 1999 and January 2012. Only patients with a minimum of 1-year follow-up were included. Clinical and radiographic assessments determined implant success and survival rates. Questionnaires recorded patients' satisfaction with esthetics, comfort, and ease of hygiene.
Of the 352 patients (n = 591 implants) who received implants over 13 years, 165 patients completed the clinical and radiographic examinations. By the end of the study period, demographic information and implant characteristics were collected for 111 (n = 217 implants; 47.5% in the maxilla, 52.6% in the mandible) of these patients. Of those assessed clinically, 36.4% were males and 63.6% females, with a mean age of 56.1 ± 14.15 years (range, 17 to 86 years) at the time of implant placement. The mean follow-up period was 5.8 years (range, 1 to 13 years). The overall implant success and survival rates were 88.0% and 97.2%, respectively. No observable bone loss was evident in 88.0% of the surviving implants. There were no implant fractures. Most patients (91.2%) were very satisfied with the implant restoration appearance, 88.0% were very comfortable with the implant, 92.6% were very satisfied with their ability to chew, and 84.8% reported easy hygiene maintenance at the implant sites.
Implant success and survival in an undergraduate student clinic were comparable to those reported in the literature. It seems that inexperienced students were able to provide restorations that were very satisfying to the patients.
本研究旨在评估在本科学生牙科诊所植入牙种植体的临床、影像学及基于患者的治疗效果。
进行一项回顾性研究，以确定1999年1月至2012年1月间在达尔豪斯大学本科牙科诊所植入牙种植体的成功率和存留率。仅纳入随访至少1年的患者。通过临床和影像学评估确定种植体的成功率和存留率。问卷调查记录患者对美观、舒适度及口腔卫生便捷性的满意度。
在13年间接受种植体植入的352例患者（共591枚种植体）中，165例患者完成了临床和影像学检查。到研究期结束时，收集了其中111例患者（共217枚种植体；上颌47.5%，下颌52.6%）的人口统计学信息和种植体特征。在接受临床评估的患者中，男性占36.4%，女性占63.6%，种植体植入时的平均年龄为56.1±14.15岁（范围为17至86岁）。平均随访期为5.8年（范围为1至13年）。种植体的总体成功率和存留率分别为88.0%和97.2%。在88.0%的存留种植体中未观察到明显的骨吸收。没有种植体折断情况。大多数患者（91.2%）对种植修复体外观非常满意，88.0%对种植体感觉非常舒适，92.6%对咀嚼能力非常满意，84.8%报告种植部位的口腔卫生维护容易。
本科学生诊所的种植体成功率和存留率与文献报道相当。似乎经验不足的学生能够提供令患者非常满意的修复体。
