Abstract

Objective: This study aimed to investigate the craniofacial features of adult Vietnamese patients with bimaxillary protrusion. Methods: Lateral cephalometric images were obtained from 130 Vietnamese adults (86 females and 44 males) diagnosed with bimaxillary protrusion at the Dental Clinic of the University of Medicine Pham Ngoc Thach. The lateral cephalometric X-rays of these patients were analyzed using Steiner and Ricketts' methods. Twelve measurements describing the most significant points of the bimaxillary protrusion malocclusion were recorded. These measurements were compared with a control group of adults with normal Class I occlusion using independent t-tests. Results: Compared to individuals with normal Class I occlusion, those with bimaxillary protrusion showed 8 significantly different characteristics (p < 0.05) and 2 characteristics with no significant difference (p > 0.05). The most noteworthy differences were related to the protrusion and inclination of the upper and lower incisors (p < 0.001). Conclusion: Adults with bimaxillary protrusion have protruding lips and incisors compared to individuals with Class I occlusion.
