Three-dimensional evaluation of the pharyngeal airway space in patients with anterior open bite

OBJECTIVE: This study aimed to three-dimensionally evaluate the pharyngeal airway space (PAS) of patients with anterior open bite (AOB) by using cone-beam computed tomography (CBCT) and compare the findings with those obtained in individuals with normal occlusion. METHODS: The open bite group (OBG,...

description OBJECTIVE: This study aimed to three-dimensionally evaluate the pharyngeal airway space (PAS) of patients with anterior open bite (AOB) by using cone-beam computed tomography (CBCT) and compare the findings with those obtained in individuals with normal occlusion. METHODS: The open bite group (OBG, n = 25) consisted of patients with an anterior overbite of –3 mm or less, while the control group (n = 25) consisted of age- and sex-matched individuals with an anterior overbite of 1–3 mm, Angle Class I malocclusion (1° ≤ point A-nasion-point B angle ≤ 4°), and a normodivergent profile (22° ≤ Frankfort mandibular plane angle ≤ 28°). After the CBCT data were reconstructed into a three-dimensional image, the PAS was segmented into four parts, and the volume of each part was measured. Pharyngeal airway length (PAL) and the area and transverse width of the part showing minimal constriction were also measured. Pearson’s correlation analysis was used to evaluate the correlation between changes in the PAS and the amount of anterior overbite. RESULTS: The OBG showed a significantly narrower airway space in the nasopharyngeal, hypopharyngeal, and total airway volumes. The OBG also showed a significantly smaller area and transverse width of the part with minimal constriction. The OBG showed a significantly longer PAL, but there was no correlation between the amount of anterior overbite and the changes in PAS. CONCLUSIONS: The PAS was associated with AOB. Patients with AOB had a narrower PAS and a smaller part showing minimal constriction.
