Effect of TiN Coating on Pure Ti Abutments for Corrosion Resistance and Peri-Implant Tissue Cells

Abstract

The present study investigated the corrosive behavior of TiN coating in fluoride solution and the effects of bacterial adherence to the surface after immersion in fluoride solution. We examined the effect of TiN coating on gingival epithelial cells and gingival fibroblasts in contact with the abutment. The dynamics of human bone marrow mesenchymal stem cells in contact with the implant were also studied using a one-piece implant (implant with the abutment and implant in one piece). This suggests that TiN coating on pure Ti abutments increases surface resistance to mechanical and chemical stress without lowering cell compatibility and maintains a smooth surface for long periods, suggesting that it is an effective surface treatment to lower the risk of peri-implantitis and other complications to oral implant therapy.
