Comparison of Relationship between Intercondylar Width and Maxillary Inter-canine Width

Aim and Objectives: To check the prevalence of facial form in dentuolous subjects in North Indian Population and to compare the relationship between inter-condylar distance and inter-canine distance which could help the dentist for the selection of maxillary anterior teeth.

Methods: A total of hundred dentate adults (20-35 years) with class 1 occlusion, having no attrition and with healthy temporomandibular joint were selected for the study. The facial form was evaluated with the Trubyte Tooth indicator. The width of the condlyes were measured between the beyron’s point with the help of facia type facebow . The width of the maxillary intercanine was measured between the tips of cuspids in both the patients mouth and the cast. Statistical analysis was performed to determine the relationship between the inter condylar width and the maxillary intercanine width.

Results: More than one third of patients had ovoid face form (35%) followed by square (33%), square tapering (18%) and tapering (14%). There was significant positive correlation between maxillary inter canine width and inter condylar width (r=0.62, p=0.0001). Both maxillary inter canine width and inter condylar width were significantly (p<0.05) higher among males than females.

Conclusion: when pre extraction records are not available, the result can help to determine the width of the artificial maxillary anterior teeth in edentulous patient.
