Experimental Study on Compressive Strength of Three Kinds of Composite Resin Veneer / 天津医药

ABSTRACT

Objective: To study the compressive strength of 3 kinds of composite resin veneer so as to provide a scientific basis forclinical application. Methods: Thirty anterior teeth were just extracted and then, their labial surfaces of crowns were restoredwith 3 kinds of light cured composite resin veneer. The most stress and compressive strength of the 3 kinds of prosthesiswere tested. Results: The compressive strength of Tetric ceram was higher than those of Charisma and Durafill (P ＜0.05).There was no significant difference between Charisma and Durafill (P＞0.05). Conclusion: The Tetric ceram is a kind ofexcellent prosthetic material as veneer constraction.
