■本文的目的是报告单件全口康复的长期结果,对患有RA和严重单侧髁再吸收的患者,按照立即加载方案进行光滑的表面植入物。
方法:这里,我们介绍了一例有挑战性的病例,即1例类风湿关节炎患者病情稳定,并成功完成了4年的随访.假肢管理优化了咬合间关系,以保持功能和审美完整性。单件植入物被设计成接合代谢活动低的皮质骨并从其获得支撑,从而促进通过接合在皮质骨中的顶端螺纹的力传递。
结论:类风湿性关节炎[RA]是一种自身免疫性炎症,其中发炎和肥厚的滑膜生长到关节表面。颞下颌关节[TM]经常与类风湿性关节炎有关。根据RA的文献,由于频繁的牙周炎,唾液分泌减少,药物,以及骨再生潜力的降低,RA通常被认为是使用植入物的相对禁忌症。萎缩性颌骨和伴有骨质疏松症等合并症的病例,糖尿病,类风湿性关节炎,牙周感染病例通过单片光滑表面修复成功。
结论:据我们所知,这可能是通过双皮质单片植入物立即功能负荷的首例。
UNASSIGNED: The aim of this article is to report the long-term outcome of full mouth rehabilitation with single piece, smooth surface implants following immediate loading protocol on a patient suffering with RA and severe unilateral condylar resorption.
METHODS: Here, we present a challenging case of a patient suffering from Rheumatoid Arthritis who was stabilized and completed successfully with a 4 year follow-up period. Prosthetic management optimized the inter-occlusal relationship to maintain both function and esthetic integrity. Single piece implants are designed to engage and take support from the cortical bone low in metabolic activities thus promoting the force transmission through apical threads that are engaged in the cortical bone.
CONCLUSIONS: Rheumatoid Arthritis [RA] is an auto-immune inflammatory condition in which the inflamed and hypertrophic synovial membrane grows into the articulation surfaces. The Temporomandibular Joints [TM] are frequently involved in rheumatoid arthritis. According to the literature on RA, due to frequent periodontitis, decreased salivary secretion, medication, as well as decrease in bone regenerative potential, RA is often considered as a relative contraindication in the use of implants. Atrophic jaws and cases with comorbidities like osteoporosis, diabetes, rheumatoid arthritis, periodontally infected cases are restored with high success by single piece smooth surface.
CONCLUSIONS: To the best of our knowledge, this may be the first case of immediate functional loading by bi-cortical single piece implants.
