| Abstract | ||||
| Objective: To evaluate the effect of two thicknesses of different veneering material on color reproduction of PEEK. Materials and Methods: The samples were divided into three main groups according to their veneering material. Group A: PEEK material veneered with IPS E.max CAD. Group B: PEEK material veneered with Visio.lign resin material. Group C: PEEK material veneered with HIPC. Each group were divided into two sub-groups according to veneering material thickness. Subgroup I: veneering material with 0.3 mm thickness. Subgroup II: veneering material with 0.5 mm thickness. The samples were cemented over BioHPP specimens of dimensions 10 x 10 mm and of thickness 0.6mm with clear resin cement and then the color of the cemented samples were examined by Aligent Cary 5000 spectrophotometer. Results: Our study detected that color change were significantly higher in E.max particularly with 0.3 mm thickness and the least color change was Visio.lign particularly with 0.5 mm thickness. Conclusion: 1. The degree of color change of the restoration materials from their selected shade is influenced by the thickness of veneering material. 2. Visio.lign has been found to be most suitable veneering material for veneering of PEEK among this study. | ||||
