Growth measurement has always been essential to identify the best time to employ orthopedic or orthodontic appliances. Optimal timing for orthodontic treatment is strictly linked to the identification of periods of craniofacial growth when treatment is more effective.The aim of this study was to compare two different methods, middle phalanx maturation (MPM) and cervical vertebrae maturation (CVM), used to evaluate the stage of facial growth.
The research data was collected from July 2018 to April 2019 at the Dental Clinic of the San Gerardo Hospital in Monza. The study included a sample of 98 patients-46 males and 52 females. For each patient, a latero-lateral teleradiography of the skull and an X-ray on the middle finger of the right hand were obtained.The statistical analysis of the comparison of the stages of skeletal maturation obtained by the MPM and CVM methods was performed using the correlation coefficient for ranks of Spearman.
A descriptive statistical analysis of the entire sample of 98 patients was performed (mean age of 12.2 years and median of 12.2 years). The average age of females in every single stage of MPM was significantly lower than the average age of males. Of the total sample, 87 patients (88.8%) showed complete agreement between the two methods.
The results obtained from the statistical analysis of this study allowed us to confirm a satisfactory agreement between the two methods.The intermediate phalanx method is a valid and alternative indicator to CVM for the identification of the puberty growth peak. We can, therefore, consider the MPM method a valid indicator of skeletal maturity.

生长测量对于确定采用矫形或正畸矫治器的最佳时机一直至关重要。正畸治疗的最佳时机与确定治疗效果更佳的颅面生长时期密切相关。本研究的目的是比较两种不同的方法，即中指骨成熟度（MPM）和颈椎成熟度（CVM），用于评估面部生长阶段。
研究数据于2018年7月至2019年4月在蒙扎圣杰拉尔多医院牙科诊所收集。该研究纳入了98例患者样本，其中46例男性和52例女性。为每位患者获取了颅骨的侧位远距X线照片和右手食指的X线照片。使用Spearman秩相关系数对通过MPM和CVM方法获得的骨骼成熟阶段进行比较的统计分析。
对98例患者的整个样本进行了描述性统计分析（平均年龄12.2岁，中位数12.2岁）。MPM各个阶段女性的平均年龄显著低于男性的平均年龄。在整个样本中，87例患者（88.8%）在两种方法之间表现出完全一致。
本研究统计分析所得结果使我们能够确认两种方法之间存在令人满意的一致性。中指骨法是用于识别青春期生长高峰的CVM的有效替代指标。因此，我们可以认为MPM法是骨骼成熟的有效指标。
