Relationship Between the Level of Vitamin D3 Deficiency and Successful Osseointegration: A Prospective Clinical Study.

Purpose: This study aimed to evaluate the influence of vitamin D3 levels on bone density, primary dental implant stability, and successful osseointegration. Materials and

Methods

Clinical and radiological examination with a standardized cone-beam computed tomography (CBCT) machine and laboratory investigation for serum levels of vitamin D3 were performed for all patients. Only patients in need of single or multiple straightforward dental implant surgery in either jaw with no history of systemic disease or condition that may interfere with bone healing were included in this study to receive the dental implant by the same oral and maxillofacial surgeon, which re-opened 4 months later to assess the osseointegration and to complete the prosthetic part.

Results

One hundred twenty-eight dental implants were inserted into 108 patients. Most of the patients in the study had insufficient vitamin D3 levels. The prognosis of dental implants regarding successful osseointegration 4 months after implant placement had a weak positive association with the insertion torque and bone mineral density and a statistically significant positive correlation with the serum vitamin D3 level.

Conclusion

Preoperatively, it is advisable to request the serum vitamin D3 level of the patients along with the standard clinical and radiological examination. Severe vitamin D3 deficiency could be associated with early dental implant failure despite the favorable bone density and primary dental implant stability achieved.
