当患者面部生长停止时，应进行单齿种植。在这项回顾性观察性研究中，我们评估了短脸、平均脸和长脸在停止颅面生长的时间上是否存在差异。根据颅基底与下颌平面夹角（SN/MP角）的值，选择3组48例短面型（SF; SN/MP = 31.5°和= 38°）。在15.4岁、2岁、5岁和10岁时，通过侧位脑电图评估面部生长情况。当两次连续测量之间的差异小于1毫米或1度时，变量被认为是稳定的。我们发现面部类型在停止面部生长的时间上没有差异。根据不同的变量，变量稳定时的平均年龄从18.0岁（LF组为Is-Pal）到22.0岁（LF组为SN/MP）。然而，在最后一次随访中，大约20%的受试者面部继续生长。这项研究表明，面部类型与面部生长停止的时间无关。(C) 2015欧洲颅颌面外科协会。Elsevier Ltd.出版。版权所有。
Placement of a single-tooth implant should be performed when a patient's facial growth has ceased. In this retrospective observational study, we evaluated if there was a difference in the timing of cessation of craniofacial growth in short, average, and long facial types. Based on the value of the angle between cranial base and mandibular plane (SN/MP angle), three groups comprising 48 subjects with short facial type (SF; SN/MP = 31.5 degrees and = 38 degrees) were selected. Facial growth was assessed on lateral cephalograms taken at 15.4 years of age, and 2, 5, and 10 years later. Variables were considered to be stable when the difference between two successive measurements was less than 1 mm or 1 degrees. We found no difference between facial types in the timing of cessation of facial growth. Depending on the variable, the mean age when variables became stable ranged from 18.0 years (Is-Pal in LF group) to 22.0 years (SN/MP in LF group). However, facial growth continued at the last follow-up in approximately 20% subjects. This study demonstrates that facial type is not associated with the timing of cessation of facial growth.
