Evaluation of the Abutment Type Following Oral Implants in Terms of the Surrounding Bone Height
- Conditions
- Missing Teeth
- Interventions
- Other: Molded abutmentOther: 3D printed abutment
- Registration Number
- NCT05350293
- Lead Sponsor
- Damascus University
- 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.

Group Intervention Description Molded abutment Molded abutment 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. A plastic abutment that the implant manufacturer provides will be used. This abutment will be modified using wax, and then it will be dismantled, wedged, and poured using a Ni-Cr mixture. 3D printed abutment 3D printed abutment The customised abutment will be made using a laser printer with a Cr-Co mixture after being designed using a special computer program.
- Primary Outcome Measures
Name Time Method Change in the crestal bone height 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 Outcome Measures
Name Time Method 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 Periodontal pockets are spaces surrounding the implant under the gum line. The pocket around the implant will be measured by using special plastic probe slides between the implant and gum to measure the depth of the periodontal pocket, and the changes in the depth of pockets will be noted and register after fixing the final prosthesis (abutment and crown), during different periods.
