Either due to trauma, extraction or congenital factors, the absence of teeth has aesthetic, functional, financial and psychological consequences. The aim of the current study is to assess an individualized polymeric 3D printed digitally planned surgical guide designed to achieve precision and predictability in non-standard mini-implant orthodontic cases. Twenty-seven patient records with missing anterior teeth were selected from the database of a private clinic in Timisoara, Romania. Based on the analysis of the cases included in the research, a surgical guide for the insertion of mini-implants as provisional crown support was designed. An FEM simulation was performed using the Abaqus numerical analysis software. Finite element simulation revealed the maximum displacements and stresses that occur in the surgical guide. Mini-implant supported provisional crowns can be a simple and low-cost method to increase patient self-esteem and compliance with the orthodontic treatment. Computer aided mechanical simulation is a useful tool in analyzing different polymeric surgical guide designs before being used in clinical situations in order to avoid failure.
无论是由于外伤、拔牙还是先天性因素，牙齿缺失都会带来美观、功能、经济和心理方面的影响。本研究的目的是评估一种个性化的聚合物3D打印数字化规划手术导板，该导板旨在在非标准微型种植体正畸病例中实现精确性和可预测性。从罗马尼亚蒂米什瓦拉一家私人诊所的数据库中选取了27例前牙缺失的患者记录。基于对研究中纳入病例的分析，设计了一种用于插入微型种植体作为临时冠支持的手术导板。使用Abaqus数值分析软件进行了有限元模拟。有限元模拟揭示了手术导板中出现的最大位移和应力。微型种植体支持的临时冠可以是一种简单且低成本的方法，以提高患者的自尊心并增强其对正畸治疗的依从性。计算机辅助力学模拟是一种有用的工具，可在临床应用前分析不同的聚合物手术导板设计，以避免失败。
