Background: To find out the corrélation of intercondylar distances with inter-canine and inter-molar distance of maxillary arch in dentate individuals among males and females of South Indian population. Materials and method: A total of120 dentate subjects of age group 24 – 60 yrs. with absence of severe crowding, trauma, orthodontic treatment and craniofacial syndrome were selected. They were equally divided into 2 groups; Group A consisting of males and Group B consisting of females. The Interfacial width(IFW) was measured by slidematic facebow (Stratos 300). The mean intermediate soft tissue thickness of 9mm on either side of face and the distance from outer side of ear bow to the tissue contact point which was measured as 30mm on each side was subtracted from interfacial width (IFW) to obtain the exact intercondylar distance (ICD). The intercondylar widths were correlated with interchained (U3) and intermolar(U6) distances which are obtained intraorally. The anthropometric measurements thus obtained was statistically analyzed to determine the importance of intercondylar distances as a guideline for complete denture fabrication in edentulous patients. Results: Since the U6/ICD ratio remains constant in group A and group B, the ICD can be used as a guideline to estimate the U6 and its bucco-palatal position, regardless of age and sex. When comparing the ICD/U3 to ICD/U6 ratios, there was a statistically significant difference. In both groups, there was no statistically significant difference in the U3/ICD and U6/ICD ratios (p>0.05) Conclusion: Thus, ICD can be used as a reliable guideline to determine the bucco-palatal position of maxillary first molar irrespective of sex. The study concludes that the clinical acceptance of this ratio can be taken as a biometric guideline for teeth arrangement as compared to the conventional guidelines in immediate denture patient.
