Objectives: The goal of this study was to see how systemic vitamin D3 supplementation affected the durability of dental implants as assessed by radiofrequency analysis.Methods: This split-mouth clinical trial included a total of twelve patients seeking dental implant therapy, ranging in age from 25 to 50 years. The patients were divided into control group and treatment group. Each patient in both groups received dental implants in posterior maxillary extraction sites. The radiofrequency analysis (RFA) was conducted using Osstell Mentor device to evaluate the stability of dental implant at various time points.Results: During the three months of the trial, substantial differences between the treatment and control groups were detected according to osstell meter device at the time of insertion (primary stability) and 3 months later (secondary stability).Conclusion: Vitamin D supplementation has a positive effect on dental implant stability.
