Chipping resistance
WebApr 1, 2024 · The tested veneering composite resins differed with regard to their mechanical properties. In view of the observed results, the material DIA may possess the highest resistance to chipping. 2. While post-processing can initially increase a material's edge chipping resistance, intensified treatment protocols resulted in reduced … WebConclusions: The examined veneering composite resins differed in regard to their mechanical properties, with DIA possessing the highest resistance to chipping. While post-processing can initially increase a material's edge chipping resistance, intensified treatment protocols reduced the mechanical properties of veneering composite resins.
