Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Implants of the Group 1 will have permanent abutments with a concave configuration of the subcritical contour (emergence shape).
Implants of the Group 2 will have permanent abutments with a convex configuration of the subcritical contour (emergence shape).
The patients will be restored with single crowns 3 months following implant installation.
A randomization protocol will be produced from a computer-generated list for the distribution of subjects in the two treatment groups.
