摘　　要：Objective This study evaluated the surface energy and resin bonding strength of several pure titanium surface modifications. Methods All pure titanium specimens divided into 4 groups according to different surface modification as H-DLC, TiN, anodizing, Untreated DLC. Using contact angle measuring machine and AGS universal testing machine to measured contact angle and resin bonding strength then calculate the surface energy. Results The resin bonding strength and surface energy of H-DLC group was higher than other group （P〈0.05）. The resin bonding strength and surface energy of TiN group was the lowest group than others （P〈0.05）. Conclusion The wettability and resin bonding strength have been increased after coating with H-DLC which can used in denture repair.
