Background: In completely edentulous patients, it is necessary to replace the teeth with at most esthetics and comfort with less patient strain. Aim: The current retrospective study was done to find the relationship between the intercondylar distance and intercanine distance of the mandible by obtaining the ratio using an orthopantomogram (OPG) for lower anterior teeth selection in completely edentulous patients. Materials and Methods: The OPG of 500 subjects was selected randomly. The OPGs were taken using the Sirona Orthophos XG machine and exposed for 14.1 s at 64 kvp, 8 mA. Then, the intercondylar distance and mandibular intercanine distance were measured from the soft copy of the OPG using the software “Sidexis.” The required measurements were taken digitally from the OPG using the software “Sidexis” in millimeters (mm). The SPSS software version 22.0 was used for statistical analysis. Results: Pearson correlation coefficients (r) displayed a significant positive association between the intercondylar distance and intercanine distance of the mandible (r = 0.42; P = 0.0002). The correlation between intercondylar width and mandibular intercanine width was significant and positive for men (r = 0.26, P = 0.0003) but negative for women (r = −0.41, P = 0.0001). The ratio between the mean intercondylar width and the mean intercanine width was 1:4.90. Conclusion: The mandibular intercanine distance and the intercondylar distance have a positive and significant association. The ratio obtained in this study was 1:4.90 between the mandibular intercanine distance and the intercondylar distance that could be employed for the choice of mandibular anterior teeth.
