To evaluate the treatment outcome of implant-supported single-tooth replacements performed by dental students as part of their undergraduate dental curriculum after a mean follow-up period of 10 years (range: 7.5 to 12 years).
A total of 51 patients were consecutively treated by dental students with 55 implants supporting single crowns. The treatment was performed under supervision of dentists and oral and maxillofacial surgeons, all with special knowledge about oral implantology. Survival of implant crown, survival of implant, probing depth, bleeding on probing and peri-implant marginal bone level change were evaluated at the end of the follow-up period. In addition, biological and technical complications during the entire follow-up period were assessed.
A total of 45 patients with 49 implants were available at the end of the study. The survival of the implant crowns as well as the implants was 94%. The mean probing depth at patient level was 4.8 mm. The probing depth varied between 2 and 10 mm at the individual site. The mean bleeding on probing score was 0.57 at patient level and absence of bleeding around all sites of the implants was rarely observed. The mean bone level change was -0.14 mm (range: 1.2 to -1.1 mm) during the first year of loading and 0.16 mm (range: 1.4 to -1.8) after 10 years at patient level. Five episodes of peri-implant inflammation due to excess cement were registered in five patients. Moreover, a fistula was observed at two implants in two patients. Finally, five technical complications occurred in five patients.
Implant-supported single-tooth replacements performed by dental students as part of their undergraduate dental curriculum were characterised by high survival rates as well as few biological and technical complications. It seems acceptable to include implant therapy in the clinical undergraduate dental curriculum, provided a focus remains on straightforward cases with substantial supervision by trained dentists and oral and maxillofacial surgeons.

评估牙科学生在本科牙科课程中进行的种植体支持单颗牙修复的治疗效果，平均随访期为10年（范围：7.5至12年）。
共有51名患者由牙科学生连续治疗，使用55颗种植体支持单冠修复。治疗在牙医和口腔颌面外科医生的监督下进行，他们均具有口腔种植学的专业知识。在随访期末评估种植体冠的存留率、种植体的存留率、探诊深度、探诊出血情况以及种植体周围边缘骨水平变化。此外，评估整个随访期内的生物学和技术并发症。
研究结束时共有45名患者的49颗种植体可用。种植体冠和种植体的存留率均为94%。患者层面的平均探诊深度为4.8毫米。各个部位的探诊深度在2至10毫米之间变化。患者层面的平均探诊出血评分为0.57，很少观察到种植体所有部位周围均无出血情况。在加载的第一年，患者层面的平均骨水平变化为-0.14毫米（范围：1.2至-1.1毫米），10年后为0.16毫米（范围：1.4至-1.8毫米）。5名患者发生了5次因多余粘固剂导致的种植体周围炎症。此外，2名患者的2颗种植体出现了瘘管。最后，5名患者发生了5次技术并发症。
牙科学生在本科牙科课程中进行的种植体支持单颗牙修复具有高存留率以及较少的生物学和技术并发症。将种植治疗纳入本科牙科临床课程似乎是可以接受的，前提是重点仍放在简单病例上，并由训练有素的牙医和口腔颌面外科医生进行大量监督。
