A three-dimensional finite element analysis for stability of mini-implant anchorage

微种植体支抗技术是一种有效增强支抗的方法,其稳定性是获得可靠支抗的必要条件。三维有限元分析法是进行生物力学分析最有效的方法之一,可模拟复杂的口颌系统,被广泛应用于正畸领域。本文就三维有限元法分析微种植体支抗初期稳定性的微种植体因素、骨因素和操作因素等研究进展进行概述,以提高微种植体支抗的成功率。

Mini-implant anchorage for the orthodontic treatment is an effective method to reinforce anchorage. The stability is critical in the achievement of reliable anchorage. Three-dimensional finite element analysis is one of the most effective method to analyze biomechanics and simulate stomatognathic system, which has been widely used in orthodontic research. We summarized the current literature on the use of the three-dimensional finite element method in primary stability of mini-implant anchorage from aspects of mini-screw implants, bone and operation, in order to improve success of implant.
