In the treatment of partially edentulous patients, implants have often been connected to natural teeth. Numerous studies have reported significant complications and problems, while others have demonstrated favorable outcomes.
The purpose of this article was to systematically review the literature regarding the splinting of implants and teeth. The difference in the biomechanical behavior between osseointegrated implants and teeth and the efficacy of the different modes of connection that have been employed are explored.
A MEDLINE search between 1966 and October 2006 was performed to retrieve relevant articles. A further manual search from the bibliographies of the former articles was performed to include as many references as possible. Prospective and retrospective clinical studies, as well as laboratory and computer-generated research, were included.
A pronounced difference in the biomechanics of teeth and implants has been revealed in theoretical models. This disparity has also been supported by the majority of the experimental work published. As a result, principal complications, such as intrusion of teeth and higher risk of overload and greater marginal bone loss around the implants have been reported. Among the several types of connections utilized, the rigid connection showed fewer complications but unfortunately did not eliminate them.
Totally implant-supported prostheses should be the treatment of choice. However, there are cases where combining teeth and implants is inevitable. The authors propose a rationale design of connecting implants and teeth. This design minimizes the biologic and technical complications.
在治疗部分缺牙患者时，常将种植体与天然牙连接。许多研究报道了严重的并发症和问题，而另一些研究则显示了有利的结果。
本文旨在系统地回顾有关种植体与天然牙固定的文献。探讨了骨整合种植体与天然牙之间生物力学行为的差异，以及所采用的不同连接方式的效果。
对 1966 年至 2006 年 10 月间的 MEDLINE 数据库进行了检索，以获取相关文章。并进一步从以前文章的参考文献中手动搜索，以纳入尽可能多的参考文献。包括前瞻性和回顾性临床研究，以及实验室和计算机生成的研究。
理论模型显示，牙齿和种植体的生物力学有明显差异。这一差异也得到了大多数已发表的实验工作的支持。因此，已经报道了一些主要并发症，如牙齿的嵌入、种植体周围更高的过载风险和更多的边缘骨丢失。在所使用的几种连接类型中，刚性连接显示出较少的并发症，但不幸的是并不能完全消除这些并发症。
完全种植体支持的修复体应是首选治疗方法。然而，在某些情况下，将牙齿和种植体结合使用是不可避免的。作者提出了一种连接种植体和天然牙的合理设计。这种设计可将生物学和技术并发症降至最低。
