THREE DIMENSIONAL EVALUATION OF CONDYLAR HEAD INCLINATION WITH RESPECT TO RAMUS AMONG POST PUBERTAL CLASS II PATTERNS
Author: Abhilasha Goyal, R. H. Kamble, Sunita Shrivastav, Narendra Sharma
Objective: To assess the condylar head inclination with respect to ramus in Angle’s Class II division 1 and division 2 skeletal patterns using Digital Volume Tomography.
Material and method: The sample consisted of 45 post pubertal patients who were divided on the basis of clinical and cephalometric analysis into three groups - skeletal Class I, Class II division 1 and Class II division 2. The selected cases underwent Digital Volume Tomography and the images obtained were used to assess condylar head inclination, mediolateral and anteroposterior thickness of the condylar head on right and left sides for all the three groups. ANOVA, Least significance difference and Paired student’s t test were done.
Results: The Class II division 2 group showed significantly more anteriorly angulated condyles as compared to those of Class II division 1 and Class I groups on both right and left sides. Class II division 1 group showed significantly smaller mediolateral dimension as compared to Class I and Class II division 2 groups. The anteroposterior dimension was not significantly different in all three groups studied.
Conclusion: There exists a variation in the condylar morphology in the various skeletal malocclusions examined. The individuals with Class II division 2 malocclusion had a tendency towards having more anteriorly angulated condyles. Also the mediolateral dimension of condylar head of individuals with Class II division 1 malocclusion is smaller than Class II division 2 and Class I malocclusions.
