This case series demonstrates the connection between dental occlusion and postural stability in patients with chronic musculoskeletal pain and instability. Assessments including dental examinations, postural analysis, and gait evaluations revealed that occlusal abnormalities directly influenced postural alignment and vice versa. Pain levels improved following posture correction and occlusal adjustments. The findings highlight the importance of interdisciplinary collaboration between dental professionals and physical therapists. By exploring mechanisms underlying the occlusion–posture relationship, this report contributes to the evidence supporting a holistic view of health. Greater awareness among healthcare providers is needed regarding the impact of dental occlusion on postural balance and overall well-being. In conclusion, dental occlusion plays a critical role in maintaining postural stability, advocating integrated, system-wide patient care.
