Comparison Between Two Different Healing Abutments in Single Posterior Implants

Comparison of Two Different Healing Abutments in Single Posterior Implants: A Randomized Clinical Trial

The aim of this randomized clinical trial is to evaluate the volumetric analysis of peri-implant soft tissues after 3 months of the use of a prefabricated healing abutment with scan peg in comparison to customized healing abutment.

Volumetric analysis of peri-implant soft tissues after 3 months of the use of a prefabricated healing abutment with scan peg with convex emergence profile in comparison to customized healing abutment with concave emergence profile.
