The aim of this prospective study was to evaluate the morbidity at the donor site following harvest of chin bone for intra-oral augmentation.
The morbidity experienced by 27 consecutive patients who had undergone chin bone harvesting to augment intra-oral sites prior to implant placement at the Department of Oral and Maxillofacial Surgery, University Dental Hospital of Manchester was evaluated at one week, one, three and 12 months post-operatively.
Nine (33%) patients suffered post-operative morbidity. One patient experienced paraesthesia of the chin and lower lip and a further patient, paraesthesia of the gingivae immediately post-operatively. Both patients had full recovery when reviewed at three months. Two patients experienced pain at the graft site for up to three months post-operatively. Five (18.5%) patients experienced woodiness/numbness of the lower anterior teeth at the first post-operative visit and at 12 months, two patients continued to have no sensitivity in the lower anterior incisor teeth. None of the patients reported altered contour or change in profile of the chin area. Twenty-three (85.2%) patients had successful grafts with placement of implants thereafter.
It is important for GDPs and specialists to make patients aware of the possible morbidities following harvest of bone from the chin.
本前瞻性研究旨在评估取自下颌骨用于口腔内种植体植入位点增骨术后供区的发病率。
对在曼彻斯特大学牙科学院口腔颌面外科连续27例于种植体植入前行下颌骨取骨以增骨口腔内位点的患者，在术后1周、1个月、3个月和12个月评估其发病率。
9例（33%）患者术后出现发病情况。1例患者术后即刻出现颏部和下唇感觉异常，另1例患者术后即刻出现牙龈感觉异常。3个月复查时，2例患者均完全恢复。2例患者术后长达3个月在植骨部位出现疼痛。5例（18.5%）患者在术后首次复诊时出现下前牙麻木/感觉迟钝，至12个月时，2例患者下前牙仍无感觉。无患者报告颏部外形改变或轮廓变化。23例（85.2%）患者植骨成功，随后植入种植体。
对于全科牙医和专科医生而言，让患者了解取自下颌骨的骨块术后可能出现的发病情况非常重要。
