A Comparative Radiographic Evaluation of Crestal Bone Loss around Dental Implants by Varying the Abutment Diameters

Abstract

The long-term preservation of safe peri-implant tissues, which can provide both function and aesthetics for a long time, is a major challenge in implant dentistry. Various approaches to reducing bone remodeling around implants have been suggested, with the impact of the implant–abutment interface being particularly important. The position of the abutment in relation to the implant platform, as well as its effect on marginal bone level changes, has piqued interest. As a result, the impact of platform switching on crestal bone remodeling around implants was investigated.

Material and Methods: The platform modification technique was used to test a series of 30 control cases and 30 research cases in this study. At 1, 4, and 6 months after abutment placement, digital radiography was used to measure interproximal bone resorption on the mesial and distal of each implant.

Results: At the mesial hand, the difference in mean score between platform matched and platform swapped abutments was non-significant (p value=0.92). At the distal side, the difference in mean score between platform matched and platform swapped abutments was statistically significant (p value=0.03). When comparing platform matched abutments to platform switched abutments, the mean reduction in bone height was higher in platform matched abutments.

Conclusion: All patients in the study group demonstrated decreased bone loss in comparison to the control group (p<0.001)
