Report on the treatment of a female patient, now 18 years old, with a bilateral continuous cleft of the lip, jaw and palate, in whom genuine ossification occurred at the jaw clefts. The upper lateral incisors and both upper canines have aligned themselves regularly in this jaw. Until now natural bone formation in a cleft jaw has been considered impossible.
关于一名现年18岁女性双侧唇、颌及腭裂患者的治疗报告，该患者颌裂处出现了真正的骨化现象。上颌侧切牙和两颗上颌尖牙在该颌骨中已正常排列。迄今为止，人们一直认为颌裂处不可能形成自然骨组织。
