When the timing of alveolar bone grafting is based on the eruptive progress of the permanent maxillary canine tooth, the surgical procedure is, by definition, delayed until the late mixed dentition phase. This treatment strategy overlooks both the crown length and the periodontal condition of the maxillary permanent incisors adjacent to the cleft defect. One should perform alveolar bone grafting at the time of eruption of the maxillary central incisor at about 5.5 to 6 years of age.
当牙槽骨移植的时机基于上颌恒尖牙的萌出进程时,根据定义,手术操作会延迟至混合牙列晚期。这种治疗策略忽视了腭裂缺损相邻上颌恒切牙的冠长和牙周状况。应在大约5.5至6岁上颌中切牙萌出时进行牙槽骨移植。
