摘要

目的:探讨金-铂合金框架全弓金属陶瓷种植体在老年患者中的应用效果。材料和方法:研究对象为全部和/或部分牙列和末端牙列缺失的患者。2007-2008年,27名患者共植入354颗种植体。患者年龄为61.31±5.08岁。采用Mombelli指数标准(mBI[修正沟出血指数])。采用改进的Löe & Silness法测定斑块指数。通过一系列OPG测定种植体周围骨的状态(ΔMBL)。采用老年口腔健康指数(GOHAI)评价老年人口腔健康状况。结果:金-铂合金框架金属-陶瓷全弓种植体在种植体数量充足且最优的基础上(6-8个),15年生存率高(100%)。15年后边缘骨质流失(ΔMBL)为-1.44±1.27 mm。种植体成活率为99.4%。术后患者的GOHAI评分从52.7±7.1分提高到54.1±8.4分。结论:15年后,所有假体均存在机械缺陷,同时可以不受限制地使用。全弓种植体假体螺钉固定虽然存在机械并发症,但可以及时进行手术干预,阻止炎症并发症的发生。因此,即使经过15年的手术,我们也没有任何理由移除金属陶瓷假体并用新的植入假体代替它们。与此同时,有必要考虑到老年患者个人口腔卫生的可能性降低,以及自行去看牙医或牙科保健师可能受到的限制。

[A prospective single-cohort study of implant-supported full-arch metal-ceramic prosthesis with gold-platinum alloy framework for treatment edentulous mandible in elderly patients: 15-year report].

Objective: To study the effectiveness of implant-supported full-arch metal-ceramic prosthesis with gold-platinum alloy framework in elderly patients.

Materials and methods: The study included patients with complete and/or partial loss of teeth and terminal dentition. In 2007-2008, 354 implants were inserted in 27 patients. The age of the patients was 61.31±5.08 years. Mombelli index criteria (mBI [modified Sulcus Bleeding Index]) were used. The plaque index was determined using a modified Löe & Silness method. The state of the peri-implant bone (ΔMBL) was determined by a series of OPG. The Geriatric Oral Health Index (GOHAI) was used to assess oral health in the elderly.

Results: Metal-ceramic full-arch implant prostheses with a gold-platinum alloy framework, based on a sufficient and optimal number of implants (6-8), showed high survival rate (100%) after 15 years. Marginal bone loss (ΔMBL) after 15 years was -1.44±1.27 mm. The survival rate of implants was 99.4%. Scores on the GOHAI scale were higher in patients after orthopedic rehabilitation (from 52.7±7.1 to 54.1±8.4, p<0.001).

Conclusion: After 15 years, all prostheses had mechanical defects, which at the same time allowed them to be used without restrictions. Screw fixation of full-arch implant prostheses, although it was associated with mechanical complications, nevertheless made it possible to perform surgical interventions in a timely manner and stop the development of inflammatory complications. Thus, we do not see any grounds for removing metal-ceramic prostheses and replacing them with new implant prostheses even after a 15-year period of operation. At the same time, it is necessary to take into account the reduction in the possibility of individual oral hygiene in elderly patients, as well as possible restrictions on self-visiting a dentist or dental hygienist.
