Purpose: The present study aimed to assess the effect of vitamin D and calcium supplement on improving overall body bone density and stability of implant placed in posterior maxilla.
Methods: The study was conducted on twelve vitamin D deficient patients indicated for posterior maxillary rehabilitation. Patients were divided into two groups: Group A received vitamin D and calcium supplement while Group B was a control group. vitamin D and calcium levels were assessed for both groups before implant placement and after a follow up period of 6 months. Two evaluation parameters were in included in this study. First parameter was overall body bone density using Dual-energy X-ray absorptiometry (DXA) while second parameter was implant stability quotient (ISQ) using Osstell device. Both parameters were measured immediately post-operative and at loading time after 6 months.
Results: Group A showed a significant increase in vitamin D levels (from 12.75 to 26.64 ng/ml). this increase in vitamin D was accompanied by increase in bone density of spine (from – 1.48 to – 1.08 T-score), and increase in stability of implants (from 44 to 74 ISQ). On the other hand, group B did not show similar improvements either at vitamin D or bone density while ISQ showed minor increase (from 58 to 69 ISQ).
Conclusion: Vitamin D and calcium supplement can play an important role on increasing overall body bone density and subsequently improving implant stability in posterior maxilla.
