Abstract

This study evaluated the fracture resistance, biaxial flexural strength (BFS), and dynamic mechanical analysis (DMA) of three-dimensional (3D) printing resins for the esthetic restoration of primary molars. Two 3D printing resins, Graphy (GP) and NextDent (NXT), and a prefabricated zirconia crown, NuSmile (NS), were tested. GP and NXT samples were 3D printed using the workflow recommended by each manufacturer. Data were collected and statistically analyzed. As a result of the fracture resistance test of 0.7-mm-thick 3D printed resin crowns with a thickness similar to that of the NS crown, there was no statistically significant difference among GP (1491.6 ± 394.6 N), NXT (1634.4 ± 289.3 N), and NS (1622.8 ± 323.9 N). The BFS of GP was higher for all thicknesses than that of NXT. Both resins showed high survival probabilities (more than 90%) when subjected to 50 and 150 MPa. Through DMA, the glass transition temperatures of GP and NXT were above 120 °C and the rheological behavior of GP and NXT according to temperature and frequency were analyzed. In conclusion, GP and NXT showed optimum strength to withstand bite forces in children, and 3D printed resin crowns could be an acceptable option for fixed prostheses of primary teeth.

摘要

本研究评估了用于乳牙美学修复的三维（3D）打印树脂的抗折性、双轴弯曲强度（BFS）和动态力学分析（DMA）。测试了两种3D打印树脂，Graphy（GP）和NextDent（NXT），以及一种预制氧化锆冠NuSmile（NS）。GP和NXT样本采用各制造商推荐的工作流程进行3D打印。收集数据并进行统计分析。对厚度为0.7毫米、与NS冠厚度相似的3D打印树脂冠进行抗折性测试的结果显示，GP（1491.6±394.6 N）、NXT（1634.4±289.3 N）和NS（1622.8±323.9 N）之间无统计学显著差异。GP在所有厚度下的BFS均高于NXT。两种树脂在承受50和150 MPa压力时均显示出较高的存活率（超过90%）。通过DMA分析了GP和NXT的玻璃化转变温度高于120°C，并分析了GP和NXT随温度和频率的流变行为。总之，GP和NXT显示出承受儿童咬合力的最佳强度，3D打印树脂冠可能是乳牙固定修复的一个可接受选择。
