Quantitative Analysis of Body Posture and Its Correlation With Cervical Posture in Various Malocclusions

Abstract

BACKGROUND: Considering that malocclusions can cause cervico-mandibular and cervico-cranial disorders, the aim of this study is to investigate whether there are significant differences in posture in subjects with skeletal class I, class II and skeletal class III malocclusion METHODS: A clinical study conducted on 90 subjects with Angle`s class I, II, III skeletal malocclusion. Standardized Casts of the subjects were used to analyze the tooth characteristics. Lateral cephalograms were used to assess cervical posture through cervical skull Rocabado analysis. A customized force platform with pressure sensors were used for posture analysis. RESULTS: There is a difference in body posture in subjects with skeletal class I, class II and class III malocclusion and a positive correlation between body posture and cervical posture is found in subjects with these classes of skeletal malocclusion. Subjects with class I malocclusion were found to have a normal cervical and body posture. Strain values from the force platform showed equal distribution of strain on both the feet. Subjects with class II malocclusion were found to have a forward cervical posture with the forward lean of body posture. Subjects with class III skeletal malocclusion were found to have a backward cervical posture with the posterior lean of body posture. CONCLUSION: The results suggest that different classes of malocclusion present with an alteration in cervical and body posture. Correction of the malocclusion or an intervention plan for the prevailing malocclusion should be done as early as possible which can be used to correct the posture thereby restoring the equilibrium of the body.

The Correlation between Malocclusion and Body Posture and Cervical Vertebral, Podal System, and Gait Parameters in Children: A Systematic Review

“…Pradeep et al underlined the intricate correlation between cervical and body posture, with class II malocclusion notably linked to increased cervical curvature and anterior head inclination. The study involved an elderly population, which is older than the participants in the other research projects [ 37 ]. The investigations by Tauheed revealed significant differences in cervical curvature among skeletal sagittal malocclusions, particularly highlighting straighter cervical columns in class III subjects [ 38 ].…”

Temporomandibular Joint Disk Displacements in Class II Malocclusion and Cervical Spine Alterations: Systematic Review and Report of a Hypodivergent Case with MRI Bone and Soft Tissue Changes

“…The lateral cephalogram of the patient is shown in Figure 2. The craniocervical posture was evaluated by performing the Rocabado analysis [39]. In the following, we evaluated: the craniovertebral angle, the hyoid bone position, and the main vertebrae distances.…”

“…The following values were found: hyoid bone position of 25.9 mm, craniovertebral angle of 100°, and occipital-atlas angle of 6.1°, and for the following vertebrae distances: C0-C1: 6.27 mm, C1-C2: 5.85 mm, C2-C3: 3.98 mm (Figure 3). The craniocervical posture was evaluated by performing the Rocabado analysis [39]. In the following, we evaluated: the craniovertebral angle, the hyoid bone position, and the main vertebrae distances.…”
