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

Digital panoramic radiographs taken during the patients' treatment periods (T0, T1) were used in the study. Measurements of marginal bone levels on radiographs were performed using the "Image J" software. The distance between the most coronal part of the implant neck and the most apical part of the defect caused by marginal bone loss was measured. Fractal analysis (FA) was conducted on panoramic radiographs (OPG) with a size of 2952x1435 pixels and a depth of 32 bits. FA on these radiographs at T0 and T1 times was performed using the box counting method determined by White and Rudolp with the ImageJ program(23). |

Marginal Bone Loss around different dental implants
Time Frame: 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. |
