title: Vitamin D deficiency as a suspected causative factor in the failure of an immediately placed dental implant: a case report.
abstract: OBJECTIVE
  To discuss the influence of Vitamin D deficiency in the osseointegration process of a dental implant by way of a case report.
  
  
  CONCLUSIONS
  A 29-year-old soldier attended clinic with a fractured mandibular premolar (tooth 44) that was traumatised following head trauma related to the detonation of an Improvised Explosive Device (IED) whilst serving on operational duty. The tooth was deemed unsalvageable and was extracted with immediate placement of a dental implant. The patient experienced no problems but at assessment, five months post-operatively, no osseo-integration of the implant was found. Concurrent medical investigations revealed that he was severely Vitamin D deficient and that this may have contributed to the implant failure.
  
  
  CONCLUSIONS
  Vitamin D deficiency may play a role in the failure of osseointegration in dental implants. The assessment of vitamin D status in patients who have been in long-term hospital care or rehabilitation should be considered, prior to the placement of dental implants.
