Abstract

Objective: To investigate the impact of serum vitamin D levels on marginal bone loss (MBL) in patients restored with unsplinted-mandibular-implant overdentures using LOCATOR attachments. Materials and Methods: Thirty participants rehabilitated with three-implant-mandibular overdentures were included. Based on serum vitamin D at the time of prosthetic loading, participants were categorized into two equal groups: a test group with deficient vitamin D (< 20 ng/mL) and a control group with sufficient levels (≥30 ng/mL). Patients with borderline levels (21–29 ng/mL) were excluded. Peri-implant vertical (VBL) and horizontal bone loss (HBL) were measured at baseline (T0), 6 months (T6), and 12 months (T12). Results: The vitamin D-deficient group exhibited significantly elevated VBL and HBLover the sufficient group at all-time points (P
