INTRODUCTION: 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.
OBJECTIVE: To determine the association between sagittal skeletal relationship (SR) and craniocervical posture (CP).
MATERIALS AND METHODS: 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 X2 tests were used at p < 0.05.
RESULTS: 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) (p < 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).
CONCLUSION: CP was associated with the sagittal SR, showing an extended posture in class II compared to other skeletal classes.
CLINICAL SIGNIFICANCE: Cephalometric study of CP should be performed at early ages to determine the skeletal class associated with an unfavorable inclination.
