“…The electrographic studies of Nascimento et al 23 found asymmetry in the suprahyoid muscular and occipital activities in Classes I and II/2nd Division during an isometric suction exercise. In this experiment, Class I recovered its symmetry, while Class II/2nd Division remained asymmetrical and with the presence of discomfort in the cervical region by overload.…”

Introduction Interdisciplinary investigative study of the stomatognathic-cervical complex, necessary to understand the structure and biomechanics of this system in Angle Class I and II / 2nd Division participants. Objective To evaluate alignment and position of cranial cervical structures on radiographs and their functional relationship with the stomatognathic system. Material and method Trans Oral and Profile radiographs were submitted to biomechanical analysis, considered the linear and angular measurement of Atlas and Axis through the application included in the radiogram software. Result We observed a significant difference in the angular measurements of vertical alignment between the Skull, Axis, and the Mandible (p = <0.001), and in the left joint between the Atlas and the Axis (AE: p = 0.011; SEA: p = 0.042). Among the linear measures of the distances between the Atlas and the Axis, the AOD distance presented statistics quite close to the level of significance (p = 0.0502), but above. There was no statistically significant difference in the other measures. Conclusion In this study, the alignment between the Atlas and Axis cervical vertebrae and the mandible and angles of the atlanto-occipital joints are altered in Class II / 2nd Division participants. There is no difference in the size and distance of the Atlas and the Axis between the Classes.

“…The craniomandibular system is widely studied in the scientific community and the interinfluence of its structures, one on the other, still generates discussions 2 . In comparative studies of Angle's Classes I and II/ 2nd Division, such as Nascimento et al 3 , it was observed that the participants of this last class, unlike the first, suffer significant impacts in the cervical region when the tongue muscles are overloaded by isometric suction exercises 3 .…”

Introduction Interdisciplinary investigative study of the stomatognathic-cervical complex, necessary to understand the structure and biomechanics of the hyoid bone and cervical spine in Class I and II / 2nd Division participants. Objective To analyze the position of the hyoid bone and the curvature of the cervical spine on lateral radiographs of participants with Class I and II/2nd Division Angle malocclusion. Material and method We evaluated the position of the hyoid bone from its alignment with the corresponding cervical vertebra. The presentation of curvature of the cervical spine was evaluated from the fourth cervical vertebra. Result There was a statistically significant difference in the position of the hyoid bone (p=0.027) between the classes, which was located at C3 in Class I and further down, between C3 and C5, in Class II/2nd Division. The cervical spine showed alterations in both classes, with an increase, rectification, and inversion of the curvature with no statistical difference between them (p=0.533). Conclusion In this study, the hyoid bone showed different positions in the malocclusions studied, however, poor posture of the cervical spine was common in both classes.

A major factor that contributes to dental malocclusions is represented by the positioning of the mandible. Considering the existing interconnections between the craniocervical and craniomandibular systems it is interesting to assess how changes in one system can influence the other, thus establishing a pattern in terms of certain cephalometric landmarks that orthodontists could consider when diagnosing and evaluating an orthodontic case. Therefore, the aim of this study was to investigate the connections between cervical posture, head position, hyoid bone position in orthodontic patients with different skeletal patterns. 45 lateral cephalometric radiographs were analyzed. Skeletal class and vertical growth were the main elements that were considered when classifying patients. Craniofacial and Cervical landmarks were determined on the cephalograms, from which lines and angles resulted which were considered relevant in our study. Correlations between cephalometric variables of the patients were determined. there were some statistically significant changes identified concerning craniocervical posture and hyoid bone position between the patients in the following parameters: H-Rgn, OPT/HOR, CVT/HOR, OPT/SN, CVT/SN, H-SN. The results obtained allowed us to conclude that there were some differences at the skeletal level of the sample of patients studied. The findings are indicating that there is a close relationship between, mandible position, cervical- and head posture and the hyoid bone. The information obtained in this study could help to better understand the development of malocclusions, and to improve the orthodontic diagnostic and treatment plan.
