Overview
Brief Summary
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.
Detailed 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.

Outcomes
Primary Outcomes
Change in the crestal bone height
Time Frame: T1:3 months after cementation, T2: 6 months after cementation, T3: 1 year after cementation
It Is the loss of bone that occurred around the dental implant neck after fixing the final prosthesis (abutment and crown). A periapical radiograph is going to be taken using a digital intra-oral sensor with a special holder in a parallel way, to measure the changes that occurred at the level of the bone around the implant depending on MBLS concept taking two referring points from the neck of the abutment to the first match of the bone with the abutment using special programs on computer (Photoshop) during different periods.
Secondary Outcomes
- Change in the depth of periodontal pockets(T1: direct after cementation, T2:3 months after cementation, T3: 6 months after cementation, T4: 1 year after cementation)
