Abstract: Background: The stomatognathic system's harmony depends on the alignment of the musculoskeletal system and mandibular rest position, both influenced by head posture. Forward head posture (FHP) alters mandibular dynamics, impacting freeway space, muscle activity, and occlusal balance. This study investigates the correlation between FHP and freeway space across different Angle's classifications of malocclusion (Class I, II, III) to provide insights for restorative dentistryMaterial and method: A cross-sectional study included 30 participants aged 18–30 years, divided equally among the three malocclusion classes. Freeway space was measured using the K7 jaw tracking device, while FHP was evaluated via craniovertebral angle (CVA) measurements obtained through lateral photographic analysis. Statistical analysis was performed using SPSS software, employing Pearson correlation and one-way ANOVA to assess relationships between variables.Results: A significant positive correlation (r = 0.41, p = 0.03) was observed between CVA and freeway space across all malocclusion types, indicating reduced freeway space with more pronounced FHP. Class II malocclusion exhibited a strong positive correlation (r = 0.93, p = 0.02) between FHP and freeway space, while Class III showed a negative, though statistically insignificant, correlation (r = -0.85, p = 0.07). Class I demonstrated a weak positive correlation (r = 0.53, p = 0.47) without statistical significance.Conclusion: This study highlights the significant relationship between FHP, freeway space, and malocclusion types, particularly in Class II. Findings emphasize the need to incorporate postural assessments into dental evaluations and treatment planning, as addressing FHP could improve stomatognathic system harmony and oral health outcomes. Further research is necessary to explore related factors like temporomandibular disorders and respiratory patterns.
