About

Compare two different types of abutments (molded abutments and computer-designed 3D printed abutments) in terms of the amount of bone loss, and depth of periodontal pockets around the implant during different periods.

Full description

In the past few years, the number of research conducted on the designs of abutments and materials has increased. Often, the restoration is done over the implant using standard abutments that the implant company prefabricated, but due to the problems facing the dentist from the occurrence of bone absorption, an increase in the depth of the pocket after restoration, other types of abutment design methods have been introduced as needed (molded abutment made by lost wax technique and computer-designed abutment made using a 3D laser printer), those customised abutments were made special for each patient depending on their conditions.

Molded abutment

Active Comparator group

Description:

A plastic abutment that is provided by the implant manufacturer will be used. This abutment will be modified using wax, and then it will be dismantled, wedged, and poured using a Ni-Cr mixture.

Experimental group

Description:

The customised abutment will be made using a laser printer with a Cr-Co mixture after being designed using a special computer program.
