Autogenous transplantation is a fast and economical option when a suitable donor tooth is available for the replacement of nonsalvageable teeth. The preservation of the periodontal ligament (PDL) cells is considered to be critical for the success of a transplanted tooth. This article presents a successful case report of autotransplantation of a mandibular third molar using a novel technique to store the donor tooth extraorally during the surgical procedure and preserve the viability of PDL cells. One year of clinical and radiographic examination revealed no signs or symptoms suggestive of any pathology and the marginal adaptation of gingiva around the donor tooth appeared to be satisfactory. Inappropriate cases, this treatment approach may be considered as an alternative to conventional prosthetic rehabilitation or implant treatment.
当有合适的供体牙可用于替换无法保留的牙齿时，自体移植是一种快速且经济的选择。牙周膜（PDL）细胞的保存被认为是移植牙成功的关键。本文介绍了一例下颌第三磨牙自体移植的成功病例报告，采用了一种新技术，即在手术过程中将供体牙保存在口腔外，并保存PDL细胞的活力。一年的临床和影像学检查显示，没有任何提示病理状况的体征或症状，供体牙周围牙龈的边缘适应性似乎令人满意。在不适合的病例中，这种治疗方法可被视为传统修复或种植治疗的替代方案。
