To discuss the influence of Vitamin D deficiency in the osseointegration process of a dental implant by way of a case report.
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.
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.
通过病例报告探讨维生素D缺乏对牙种植体骨结合过程的影响。
一名29岁的士兵因下颌前磨牙（44号牙）骨折前来就诊，该牙在执行任务时因简易爆炸装置爆炸导致头部受伤而受创。该牙被判定无法保留，遂拔除并立即植入牙种植体。患者术后无任何问题，但术后五个月进行评估时，发现种植体未发生骨结合。同时进行的医学检查显示，他严重缺乏维生素D，这可能是种植体失败的原因。
维生素D缺乏可能在牙种植体骨结合失败中起作用。在植入牙种植体之前，应考虑对长期住院治疗或康复患者的维生素D状况进行评估。
