Selection of maxillary anterior teeth for complete dentures is crucial in clinical practice and controversy about the validity of even the best method to employ still exists. Leon Williams formulated and publicized a method called the “Geometric theory” which is still widely used. Williams believed that there exists a relationship between the face-form and the form of the maxillary central incisor in most people and that this relationship should be taken into account in the tooth selection procedure.A Cross-sectional, descriptive study was conducted in an institution, on randomly selected individuals. The study group consisted of adult patients who attended the outpatient Department of Prosthodontics from June 2019- March 2020.86000 case sheets were evaluated and Chi-square test and frequency analysis was used to explore the relationship between two variables.Leon Williams criteria was fulfilled by only 41% individuals Ovoid face form 41% is more common in indian population as compared to other forms.Ovoid and square tapering tooth forms are more common compare to other tooth forms 30% with square tooth form being the least 12%.In females leon williams criteria was more matched than males. But the difference was not significant. This study concludes that there is a much greater percentage of dissimilarity between incisor and face-form, in sample Indian population. The “Williams’ law of harmony” to select artificial teeth stands inconclusive in the sample Indian population both in males and females.

Recent advances in ceramics have greatly improved the functional and esthetic properties of restorative materials.New materials offer an esthetic and functional oral rehabilitation, however their impact on opposing teeth is not well documented.The aim of the study was to evaluate prevalence of different materials for full veneer crowns used by dentists for a single full veneer crown based on location and choice made by dentist..A Cross-sectional, descriptive study was conducted in an institution, on randomly selected individuals. The study group consisted of adult patients who attended the outpatient Department of Prosthodontics from June 2019- March 2020.86000 case sheets were evaluated and frequency distribution test was used to explore the relationship between two variables.Comparison of the groups showed that Hand layered zirconia crown was preferred by 42.3 % individuals.Metal ceramic was predderd by 10.3% of the individuals.Monolithic zirconia was preferred by 47.4 % of the individuals.With the era of metal free crowns monolithic is preferred to solve the chipping problems which are to be considered before getting a hand layered zirconia crown or a metal ceramic crown.
