Introduction: Temporomandibular joint plays an important role in maintaining a balance between structures of oral-facial complex. And morphology of Condyle is an essential part of temporomandibular joint that response to functional load, masticatory muscle activity constantly even after completion of the growth. Therefore, its morphology directs the adaptations to these functional forces. Aim: To evaluate the TMJ morphology characteristics in various growth patterns using CBCT. Materials and Methods: The present study was conducted to evaluate and compare morphology of TMJ in different vertical growth pattern individuals in North Indian population using CBCT. Pretreatment cone-beam computed tomography (CBCT) images of 10 Hypodivergent, 10 Normodivergent and 9 Hyperdivergent subjects were analyzed using SN- mandibular plane angle. Morphological parameters of TMJ such as anterior, superior, posterior joint space, condylar axial angle, mandibular fossa depth, intercondylar distance, medio-lateral and anterio-posterior width were measured and statistical analysis were done using One Way ANOVA and Post hoc Tukey test. Results: A statistically significant difference was noted in the superior joint space among Group I(4.04±0.10), Group II(3.73±0.36) and Group III(3.06±0.22)with p=0.00 and significantly correlated to facial morphology. Conclusion: TMJ morphology varies according to different growth patterns.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
