Investigation of Marginal Bone Loss in Implants with Different Surface Properties and Geometric Designs: a Retrospective Clinical Study

Not Applicable

Completed

• Conditions: Implant Infection; Peri-Implantitis; Bone Loss
• Interventions: Other: dental implant

• Registration Number: NCT06148012
• Lead Sponsor: Recep Tayyip Erdogan University

Brief Summary

Purpose: The aim of this study was to investigate the influence of surface characteristics and geometric design on marginal bone loss and bone quality in dental implants.

Materials and Methods: A total of 378 implants from 114 patients were evaluated in this study using panoramic and periapical radiographs. Implants were categorized into 19 subgroups according to the jaw where they were placed, length, diameter, surface preparation, type of prosthetic superstructure, and neck design. Radiological evaluations were conducted based on radiographs obtained at the time of implant placement and 3 months after prosthetic loading. After obtaining measurements of marginal bone loss and fractal analysis data, the significance of differences between groups was statistically evaluated.

Primary Outcome Measures

Name	Time	Method
Marginal Bone Loss around different dental implants	180 days	Number of Participants: 114 Number of Dental Implants: 378; Implants will be categorized into 19 subgroups according to the jaw where they were placed, length, diameter, surface preparation, type of prosthetic superstructure, and neck design. Radiological evaluations will be conducted based on radiographs obtained at the time of implant placement and 3 months after prosthetic loading.; The distance between the most coronal part of the implant neck and the most apical part of the defect caused by marginal bone loss(millimeters) will be measured. The magnification ratio will be calculated by comparing the previously recorded implant length with the length measured on the software, allowing the determination of the actual value of MBL.
Fractal values around dental implant radiographs	180 days	A total of 378 implants from 114 patients will be evaluated in this study using panoramic and periapical radiographs. Implants will be categorized into 19 subgroups according to the jaw where they were placed, length, diameter, surface preparation, type of prosthetic superstructure, and neck design. Radiological evaluations will be conducted based on radiographs obtained at the time of implant placement and 3 months after prosthetic loading. And measurement pre op post op fractal values
