Tooth misalignment and malposition are common oral health problems. It is important to evaluate the factors associated with malocclusion in order to observe the behavior of the occlusion.
To determine the association between sagittal skeletal relationship (SR) and craniocervical posture (CP).
This retrospective study evaluated 187 digital lateral radiographs of Peruvian children and the C0-C1 (suboccipital space) and (90 males and 97 females) aged 6-12 years (mean age: 10.16 ± 1.54 years). Sagittal SR included the ANB angle according to Steiner analysis and the anteroposterior dysplasia indicator (APDI) angle (indicator of anteroposterior dysplasia) according to Kim analysis in class I (ANB 0-4°, APDI 78-84°), class II (ANB >4°, APDI <78°), and class III (ANB <0°, APDI >84°). CP was assessed with Rocabado analysis according to the MGP-OP angle (craniocervical rotation) and the CO-C1 (suboccipital space) and H (position of the hyoid bone) distances. ANOVA, Kruskal-Wallis, Spearman correlation, and Pearson's tests were used at < 0.05.
A very low to low significant correlation was found between ANB with MGP-OP (rho = -0.195) and CO-C1 (rho = 0.173) and H (rho = 0.173) and H (rho = 0.164) and between APDI with MGP-OP (rho = 0.176) and H (rho = -0.161) ( < 0.028). A greater H distance was associated with APDI class II (p = 0.021) and a lower MGP-OP value was related to ANB and APDI class II, especially in girls (p ≤ 0.004).
CP was associated with the sagittal SR, showing an extended posture in class II compared to other skeletal classes.
Cephalometric study of CP should be performed at early ages to determine the skeletal class associated with an unfavorable inclination.

牙齿排列不齐和错位是常见的口腔健康问题。评估与错牙合相关的因素对于观察咬合行为很重要。
确定矢状面骨骼关系（SR）与颅颈姿势（CP）之间的关联。
这项回顾性研究评估了187张秘鲁儿童（90名男性和97名女性）6至12岁（平均年龄：10.16±1.54岁）的数字化侧位X线片以及C0-C1（枕下间隙）。矢状面SR包括根据Steiner分析的ANB角以及根据Kim分析的I类（ANB 0-4°，APDI 78-84°）、II类（ANB>4°，APDI<78°）和III类（ANB<0°，APDI>84°）的前后发育异常指标（APDI）角（前后发育异常指标）。根据MGP-OP角（颅颈旋转）以及CO-C1（枕下间隙）和H（舌骨位置）距离，采用Rocabado分析评估CP。使用方差分析、Kruskal-Wallis检验、Spearman相关性分析和Pearson检验，检验水准设定为α<0.05。
发现ANB与MGP-OP（rho=-0.195）、CO-C1（rho=0.173）以及H（rho=0.173）和H（rho=0.164）之间以及APDI与MGP-OP（rho=0.176）和H（rho=-0.161）之间存在非常低到低的显著相关性（P<0.028）。H距离增大与APDI II类相关（P=0.021），而较低的MGP-OP值与ANB和APDI II类相关，尤其是在女孩中（P≤0.004）。
CP与矢状面SR相关，与其他骨骼类型相比，II类表现出伸展姿势。
应在早期对CP进行头影测量研究，以确定与不良倾斜相关的骨骼类型。
