Abstract
BACKGROUND: Implant failure may necessitate another surgical procedure to improve implant survival. Photofunctionalization(PF) with UV light is a promising method to enhance dental implant osseointegration. The study evaluates the effect of the PF on bone quality around the implants using Fractal Dimension Analysis (FDA). METHODS: A total of 42 implants were placed in a split-mouth design and evaluated using FDA on panoramic radiographs taken pre- and post-operatively. Regions of interest (25 × 25 pixels) were analyzed using ImageJ. Statistical analysis used SPSS 26 with a 95% confidence level. Shapiro-Wilk test confirmed non-normal distribution. RESULTS: A statistically significant increase in Fractal dimension(FD) values was observed in the test group between pre- and post-operative images (p = 0.044). The control group showed a non-significant increase (p = 0.794). CONCLUSIONS: PF appears to enhance osseointegration by improving bone microstructure as shown by increased FD values. FDA is a reliable imaging-based proxy for evaluating implant-related bone changes.
