Abstract

The thickness of a material has a significant impact on its fracture load. The aim of the study was to find and describe a mathematical relationship between the material thickness and the fracture load for dental all-ceramics. In total, 180 specimens were prepared from a leucite silicate ceramic (ESS), a lithium disilicate ceramic (EMX), and a 3Y-TZP zirconia ceramic (LP) in five thicknesses (0.4, 0.7, 1.0, 1.3, and 1.6 mm; n = 12). The fracture load of all specimens was determined using the biaxial bending test according to the DIN EN ISO 6872. The regression analyses for the linear, quadratic, and cubic curve characteristics of the materials were conducted, and the cubic regression curves showed the best correlation (coefficients of determination (R): ESS R = 0.974, EMX R = 0.947, LP R = 0.969) for the fracture load values as a function of the material thickness. A cubic relationship could be described for the materials investigated. Applying the cubic function and material-specific fracture-load coefficients, the respective fracture load values can be calculated for the individual material thicknesses. These results help to improve and objectify the estimation of the fracture loads of restorations, to enable a more patient- and indication-centered situation-dependent material choice.

摘要

材料的厚度对其断裂载荷有重大影响。本研究的目的是找出并描述牙科全陶瓷材料厚度与断裂载荷之间的数学关系。总共从白榴石硅酸盐陶瓷（ESS）、二硅酸锂陶瓷（EMX）和3Y-TZP氧化锆陶瓷（LP）制备了180个试样，有五种厚度（0.4、0.7、1.0、1.3和1.6毫米；n = 12）。根据DIN EN ISO 6872，使用双轴弯曲试验测定所有试样的断裂载荷。对材料的线性、二次和三次曲线特征进行了回归分析，三次回归曲线显示出与断裂载荷值作为材料厚度函数的最佳相关性（决定系数（R）：ESS，R = 0.974；EMX，R = 0.947；LP，R = 0.969）。对于所研究的材料，可以描述出一种三次关系。应用三次函数和材料特定的断裂载荷系数，可以为各个材料厚度计算出相应的断裂载荷值。这些结果有助于改进和客观评估修复体的断裂载荷，以便能够根据患者和适应证更有针对性地选择材料。
