Relationship between Maxillary Sinus Hypoplasia and Maxillary Occlusal Cant: A Cone Beam CT Study

Introduction. Maxillary sinus hypoplasia (MSH) has been reported to cause a cant in the orbital plane. No similar reports exist about possible impact on maxilla. The aim of this study was assess if MSH is associated with maxillary occlusal plane (MOP) and dental or mandibular factors influenced existence MOP cant. Methods. 80 cone beam CT images subjects were analyzed for type MSH, degree cant, open cross bite, asymmetry, degenerative joint disease temporomandibular joints. compared control group matched by age gender. Results. (range 0–5.1°) not statistically significantly different unilateral vs. bilateral between types MSH. frequency crossbite, different. Between case control, there no significant difference ( 1.3 ± 1.1 ° id="M2"> 0.9 , respectively) factors. There low positive linear correlation symmetry (Spearman’s id="M3"> rho = 0.23 ) controls id="M4"> 0.18 7). Conclusions. data suggests view alveolar bone as adaptable skeletal unit ensure bridge functionality nasomaxillary complex TMJ system–two systems very function, therefore largely independent “matrix units.”
