Back ground: Natural tooth shape and size varies from one individual to other. In absence of pre-extraction records exact shape and size of teeth cannot be determined.
The aim of this study is to estimate the biometric ratio of the width of maxillary anterior teeth with craniofacial landmarks.
Materials and Methods: The study was conducted 0n 200 Indian People in the age group ranged from 21-30 years. All the subjects participating in the study were students of Rama Dental College & Hospital. In this study methods A, B, C and D were measurements of the horizontal cranial circumference, the interzygomatic distance, the interalar distance and the mesiodistal width of individual maxillary anterior teeth were directly recorded on the subject.
Results: It was observed that there was no appreciable variation in the ratio of the horizontal cranial circumference and interzygomatic distance to that of maxillary anterior teeth in both sexes. Statistically significant difference was observed in the ratio values of interalar distance to that of maxillary anterior teeth among males and females.
Conclusion: It can be concluded that the ratio of the horizontal cranial circumference and interzygomatic distance to that of maxillary anterior teeth can be used for the selection of proper size of maxillary anterior teeth in edentulous patients in both sexes.
Key words: Craniofacial land marks, Intercanine distance, Biometric ratio.
