Abstract：
OBJECTIVE: In this case, the patient with ectodermal dysplasia lost his teeth and acquired maxillary insufficiency. The aim of this case is to advance the maxilla using Le Fort I surgery and make fixation with a subperiosteal implant.
METHODS: On the three-dimensional model, a surgical guide for Le Fort I osteotomy and subperiosteal implant design was planned. In the surgery, Le Fort I osteotomy was made according to the guide, and maxillary advancement was obtained, then a subperiosteal implant was fixated. Prosthetic rehabilitation was made after 1 month.
RESULTS: Maxillary repositioning is obtained according to virtual planning and subperiosteal implant is used for both fixation and prosthetic rehabilitation. Proper fixation is ensured and full arch prosthetic rehabilitation supported by a subperiosteal implant is performed.
CONCLUSIONS: With this technique, in the rehabilitation of atrophic maxilla, sagittal insufficiency is corrected with Le Fort 1 surgery, whereas the patient\'s treatment period is shortened by placing a subperiosteal implant at the same time.

摘要：
目的：在这种情况下，外胚层发育不良的患者失去了牙齿并获得上颌功能不全。这种情况的目的是使用LeFortI手术推进上颌骨，并用骨膜下植入物进行固定。
方法：在三维模型上，计划了LeFortI截骨术和骨膜下植入物设计的手术指南。在手术中,LeFortI截骨术是根据指南进行的，并获得上颌前移，然后固定了骨膜下植入物。1个月后进行假肢康复。
结果：上颌骨重新定位是根据虚拟计划获得的，骨膜下植入物用于固定和假体康复。确保了正确的固定，并进行了由骨膜下植入物支持的全足弓假体康复。
结论：使用这种技术，在萎缩性上颌骨的康复中，通过LeFort1手术纠正矢状功能不全，而同时放置骨膜下植入物可缩短患者的治疗期。
