Abstract:

Objective This study aimed to compare the stress distribution in the left maxillary first molar restored with an occlusal veneer made of two kinds of materials with different thickness and provide a theoretical reference for the clinical application of occlusal veneer. Methods Micro CT data of the left maxillary first molar were extracted and four finite element models of the left maxillary first molar with an occlusal veneer of different thicknesses (0.6 and 1.0 mm) and different materials [IPS e.maxCAD (LD) and Lava Ultimate (LU)] were established, respectively, LD0.6, LD1.0, LU0.6, and LU1.0. Then, the axial load F1 and lateral load F2 of the maxillary first molar were simulated. The maximum principal stress (MaxPS) and minimum principal stress (MinPS) of occlusal veneer, tooth tissue and adhesive layer were recorded under two kinds of loads. The MaxPS and MinPS were quantitatively analyzed by percentage quantification and the failure probability of the models was calculated using Weibull analysis. Results 1) Only the enamel reached the tensile strength of the material. 2) In each group, the MaxPS and the absolute value of MinPS of occlusal veneer of LD-restored teeth were significantly higher than that of LU-restored teeth, with variations of 11.4%- 34.7% and from -18.2% to -9.5%, respectively. However, the MaxPS (from -187.1% to 2.4%) and the absolute value of MinPS (from -1.4% to 16.9%) of tooth tissue and adhesive layer of LD-restored teeth were lower than those of LU-restored teeth. When the restoration thickness increased from 0.6 mm to 1.0 mm, the MaxPS and the absolute value of MinPS of occlusal veneer of LD-restored teeth significantly decreased, with variations from 20.0% to 21.0% and from -5.7% to -3.9%, respectively, whereas that of LU-restored teeth did not change. 3) The failure probability of overall models of F1 and F2 was LU0.6>LU1.0>LD0.6> LD1.0 and LU0.6>LU1.0>LD1.0>LD0.6, respectively. Moreover, the failure probability of F1 was lower than that of F2. Conclusion 1) Compared with LU, occlusal veneer made by LD takes on more stress to protect the dental tissue and adhesive layer. 2) The thickness has a significant effect on the stress distribution of LD, but not on LU.
