Primary Outcome Measures

Name	Time	Method
Measurement of peri-implant soft tissues volume	3 months	Each participant will undergo volumetric analysis of peri-implant soft tissues after 3 months healing either after using prefabricated healing abutment with scan peg in comparison to customized healing abutment using a 3D meteorology software (GOM inspect). It will be measured in millimeter cube
