A 22-year old male was referred to the Department of Oral and Maxillofacial Surgery of a university clinic 2 months after he had sustained multiple traumatic injuries abroad because of an anterior malocclusion. The malocclusion was the sequel of an unrecognised, untreated, already consolidated paramedian mandibular fracture on the right and a fracture of the contralateral mandibular angle on the left. Preoperatively, a cobalt-chrome 3D-printed dental splint was prepared. Surgical correction of the malocclusion was carried out by segmental osteotomies of the mandible at the original fracture sites. This involved a vertical paramedian osteotomy on the right side and a unilateral sagittal split osteotomy on the left mandibular angle side. The mandibular segment was mobilised in the correct occlusion with the aid of the 3D-printed dental splint. The splint was fixed to the teeth with dental composite. The custom made 3D-printed dental splint is considered a promising procedural innovation in oral and maxillofacial surgery.
一名22岁男性在国外因前牙咬合不正遭受多处创伤性损伤两个月后，被转诊至一所大学诊所的口腔颌面外科。这种咬合不正是右侧未被识别、未治疗且已愈合的下颌旁正中骨折以及左侧对侧下颌角骨折的后遗症。术前，制备了一个钴铬合金3D打印牙夹板。通过在原骨折部位对下颌骨进行节段性截骨术来手术矫正咬合不正。这包括右侧的垂直旁正中截骨术和左侧下颌角侧的单侧矢状劈开截骨术。借助3D打印牙夹板将下颌节段移动到正确的咬合位置。用牙科复合材料将夹板固定在牙齿上。定制的3D打印牙夹板被认为是口腔颌面外科一项有前景的程序创新。
