摘要

目的评估使用固定修复体进行种植治疗后,在10年观察期内的维护治疗成本和工作量:这项随机对照临床试验包括 64 名患者,他们被随机分配到两种种植系统(AST 或 STM)和固定修复体中的一种。患者被纳入定期维护计划,并在装模、1、3、5、8 和 10 年时接受检查。结果测量包括技术和生物学并发症,以及解决这些并发症所需的时间、精力和费用:64名患者共植入了97颗种植体(AST:54颗,STM:43颗)。患者在 5 年和 10 年后的召回率分别为 89% 和 67%。一般来说,技术并发症可在一到两次就诊(平均=1.5次)内解决,生物并发症平均需要1.3次就诊。10年间,每年定期维护的总时间为77分钟。39.5%的患者出现了技术并发症,其中最常见的是螺钉松动(占所有并发症的43.4%)。最耗时的技术并发症是基台断裂(94 分钟 ± 68),其次是螺钉断裂(84 分钟 ± 38)。患者种植体周围粘膜炎的发病率为30.2%,种植体周围炎的发病率为9.3%。10年间,每年的平均维护费用占种植治疗初始费用的9%:结论:在种植牙时,必须考虑到额外的定期维护成本和治疗潜在并发症的成本。大多数技术并发症都可以在一次就诊中得到解决,而对于种植体周围炎,治疗生物并发症所需的时间则从一次到三次不等。

Maintenance Costs, Time, and Efforts Following Implant Therapy With Fixed Restorations Over an Observation Period of 10 Years: A Randomized Controlled Clinical Trial.

Objectives: To assess the costs and efforts of maintenance therapy following implant treatment with fixed restoration over an observation period of 10 years.

Material and methods: This randomized controlled clinical trial included 64 patients who were randomly assigned to receive one of two implant systems (AST or STM) and fixed restoration. Patients were included in a regular maintenance program and were examined at loading, 1, 3, 5, 8, and 10 years. Outcome measures included technical and biological complications, time, efforts, and costs to resolve them.

Results: A total of 97 implants were placed in 64 patients (AST: 54, STM: 43). Patient recall rates at 5 and 10 years were 89% and 67%. In general, technical complications were resolved within one to two appointments (mean = 1.5), and biological complications required a mean of 1.3 appointments. The overall regular maintenance time for the period of 10 years amounted to 77 min per year. Technical complications occurred in 39.5% of the patients, with screw-loosening being the most common one (43.4% of all complications). The most time-consuming technical complication was abutment fracture (94 min ± 68), followed by screw fracture (84 min ± 38). The prevalence of peri-implant mucositis on the patient level was 30.2%, and it was 9.3% for peri-implantitis. The average annual maintenance costs amounted to 9% of the initial cost of the implant treatment over the period of 10 years.

Conclusions: Additional regular maintenance costs and costs due to the treatment of potential complications have to be taken into consideration when placing dental implants. The majority of technical complications could be resolved within one appointment, whereas the time needed to treat biological complications varied between one and three appointments for peri-implantitis.
