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.

Trial registration: Current Controlled Trials NCT06821932 (Retrospectively registered) ( https://clinicaltrials.gov/study/NCT06821932 /2025-02-11).

分形分析方法评价光功能化种植体周围骨结构：一项裂口随机临床研究。

背景：种植体失败可能需要另一种外科手术来提高种植体的存活率。紫外光光功能化（PF）是一种很有前途的增强种植体骨整合的方法。本研究采用分形维数分析（FDA）评价PF对种植体周围骨质量的影响。方法：采用裂口设计放置42颗种植体，术前和术后采用全景x线片进行FDA评价。使用ImageJ分析感兴趣的区域（25 × 25像素）。统计学分析采用SPSS 26，置信水平为95%。Shapiro-Wilk检验证实非正态分布。结果：试验组分形维数（FD）值与术前术后比较差异有统计学意义（p = 0.044）。对照组无显著性升高（p = 0.794）。结论：从FD值的增加可以看出，PF通过改善骨微观结构来促进骨整合。FDA是评估种植体相关骨变化的可靠的基于成像的代理。试验注册：当前对照试验NCT06821932（回顾性注册）（https://clinicaltrials.gov/study/NCT06821932 /2025-02-11）。
