Evaluation of the role of skull anthropometry for complete denture teeth selection: A cross-sectional study.

Background: Success of complete denture treatment lies in the ability to make it indiscernible from the natural. The selection of the six maxillary anterior teeth is of utmost importance as it contributes most to denture esthetics. Although various techniques and methods to determine the width of maxillary anterior teeth and its relation to various body measurements were done, the simple technique of using circumference of head has been less documented, specifically for Indian population.

Aims and Objective: The aim of this study was to determine whether a relationship exists between the widths of the upper six anterior teeth to head circumference and the objective was to decide whether head circumference can be used as a deciding criterion to select size of maxillary anterior teeth for Central Indian population.

Materials and Methods: This study was done on 300 people who included 135 males and 165 females. The circumference of head (A) and the combined width of the six anterior maxillary teeth (B) were measured and the ratio of A: B was determined.

Results: EPO Info software version 6 was used to derive the statistical analysis with unpaired Student's t -tests. In male students, the mean of the ratio between the head circumferences to the combined widths of the anterior maxillary teeth was 10.14:1. In female students, the mean of the ratio between the head circumferences to the widths of the anterior maxillary teeth was 10.09:1. The average circumference of head to mesiodistal width of six anterior teeth ratio was concluded to be 10.

Conclusion: Within the limitations of this study, the results suggest that head circumference divided by 10 can be used to select a teeth set with the resulting value as the combined mesiodistal width of six anterior teeth. This can be used as a starting point for determining the width of the anterior maxillary teeth for edentulous patients, which can be further confirmed with the esthetic appearance and with other facial measurements.
