Evaluation of Peri-Implant Bone Changes with Fractal Analysis

Area of Science:

• Biomaterials Science
• Dental Implantology
• Radiology

Background:

• Postoperative monitoring of dental implant osseointegration requires accurate scientific methods.
• Assessing peri-implant bone changes is crucial for long-term implant success.

Purpose of the Study:

• To evaluate peri-implant bone changes using fractal analysis (FA) during the follow-up period.
• To assess the correlation between bone remodeling and FA results after dental implant placement.

Main Methods:

• Periapical radiographs from 77 dental implant patients and 33 control teeth were analyzed.
• Fractal analysis (FA) was performed on digitized radiographs using ImageJ software.
• Regions of interest (ROIs) were selected from mesial and distal aspects of implants for FA.

Main Results:

• No significant FA value differences were found over time based on gender or age.
• Statistically significant differences in FA value changes were observed over time and between jaws.
• A positive correlation was noted between bone remodeling and FA results.

Conclusions:

• Fractal analysis (FA) is a practical and cost-effective diagnostic tool for monitoring bone density changes.
• FA can detect bone remodeling associated with restored masticatory forces in the implant area.
• Two-dimensional dental radiograph image analysis aids in assessing peri-implant bone density changes.
