Background & Objective: To report the results of evaluation of the color digital subtraction technique in assessing quality and quantity peri-implant bone changes in dental x-ray imaging.

Methods & Materials: Twenty dental implants were performed in the maxillary posterior regions of 20 patients (age range 22-39).

Digital periapical radiographic images were taken for implants in 5 consecutive follow up visits and processed using Emago advanced/5.3 software program.

A region of interest (ROI) were determined in the mesial cervical area of each implant in the resulted images from which the total surface resorption (TS), the surface of bone resorption (RS) and the radiographic bone density alteration were calculated for comparison.

Results: Color subtraction precisely determined the bone alterations (TS and RS) as indicated by the statistically significant inverse relationship between each of them with radiographic bone density alteration; however, it was higher for RS (0.914-0.984) than TS (0.549-0.897).

Conclusion: Color coding logarithm of digital color subtraction technique in X-ray dental imaging is precise in detecting and computing the quantitative and qualitative peri-implant bone changes
