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.

Inclusion Criteria:

• Implants with a minimum length of 8 mm
• Implants with a minimum diameter of 3.5 mm
• Availability of panoramic and periapical radiographs at T0 (immediately after surgery) and T1 (3 months after prosthetic loading).

Exclusion Criteria:

• Presence of a systemic condition hindering dental implant treatment and routine check-ups
• History of regular alcohol/tobacco use
• Presence of severe parafunctional habits (bruxism, etc.)
• Prior grafting procedures before dental implant placement
• Implant failure
