Correlation of Oral Health-Related and Living Quality of Life in Malocclusion Patients Treated with a Combined Orthodontic and Maxillofacial Surgical Approach.

Introduction: Patients with malocclusion often require orthodontic treatment as well as maxillofacial surgery, to improve facial asymmetry and restore bite function. Typically, patients experience post treatment pain, psychological and social adjustment, social interactions. Materials and Methods: A cross-sectional study was conducted on 120 patients with skeletal malocclusion who completed combined orthodontic and orthognathic surgery. OHRQoL was assessed using Oral Health Impact Profile-14 (OHIP-14), and overall quality of life was measured with WHO Quality of Life-BREF (WHOQOL-BREF). Data were analyzed using Pearson's correlation. Results: Patients showed significant improvement in both oral health and overall quality of life. A strong negative correlation was found between OHIP-14 and WHOQOL-BREF scores (r = -0.64, P < 0.001), indicating that better oral health is associated with higher life quality. Conclusion: Combined treatment enhances both OHRQoL and general well-being, supporting a holistic, patient-centered approach in managing malocclusion.
