The study is aimed to assess the effects of serum vitamin D levels and their relationship to early dental implant failures. A total of 174 implants in 109 patients were placed and serum vitamin D levels were noted on the day of implant placement. Implants were followed up until restoration, approximately 3-6 months later, and any implant failure was reported based on 50% or more bone loss or implant mobility. Eight individuals had an implant fail early and their vitamin D levels had a mean of 42.54 ng/mL compared with the successful patients' levels of 31.92 ng/mL. Although not statistically significant, there was no correlation between patients' low serum vitamin D levels and early implant failure.
