Healing Abutment Materials on Matrix Metalloproteinase-8 Level in Peri-implant Crevicular Fluid

Effect of Two Different Healing Abutment Materials on Matrix Metalloproteinase-8 Level in Peri-implant Crevicular Fluid (a Randomised Clinical Trial)

Numerous materials are nowadays used in the fabrication of healing abutments to be used for dental implants. soft tissue response to different healing abutment materials is still to be unraveled. the Aim of this study is to compare the soft tissue response to titanium stock healing abutments to customized composite healing abutments through assessing the level of matrix metalloproteinase-8 in the peri-implant crevicular fluid
