The design of dental implants has undergone minor modifications over the years to reduce possible future complications that may arise from implant rehabilitation. One critical element from a clinical point of view is the implant connection. Given this, the team of authors of the present study decided to biomechanically analyze the effect of implant connection obtained in a possible implant fracture through a systematic review of the published literature. To this end, a search was conducted in the PubMed and Scopus databases. Only finite element studies carried out in vitro and simulation studies were included, discarding clinical studies and related reviews. A total of 19 studies were obtained for analysis and complete study. The conical type is the connection design that demonstrates the best biomechanical behavior. However, there was also significant heterogeneity in the design of the studies, which translates into a substantial source of bias, as well as different types of specific designs within the conical connection. In conclusion, it was established that the design of the connection seems to play a fundamental role in the fatigue resistance of the implant when subjected to load. However, more studies are needed to determine the most optimal specific design.
多年来，牙科植入物的设计经历了一些细微的修改，以减少植入物修复可能引发的未来并发症。从临床角度来看，一个关键因素是植入物连接。鉴于此，本研究的作者团队决定通过对已发表文献的系统回顾，从生物力学角度分析植入物连接对可能发生的植入物骨折的影响。为此，在PubMed和Scopus数据库中进行了检索。仅纳入了体外进行的有限元研究和模拟研究，排除了临床研究及相关综述。共获得19项研究进行分析和完整研究。锥形连接设计展现出最佳的生物力学性能。然而，研究设计中也存在显著的异质性，这成为了一个重大的偏差来源，并且在锥形连接中还有不同类型的具体设计。总之，已确定连接设计在植入物承受负荷时的抗疲劳性方面似乎起着至关重要的作用。然而，需要更多研究来确定最优化的具体设计。
