RESUMO
The sole objective of casting procedure is to provide a metallic duplication of missing tooth structure, with as great accuracy as possible. The ability to produce well fitting castings require strict adherence to certain fundamentals. A study was undertaken to comparatively evaluate the effect on casting accuracy by subjecting the invested wax patterns to burnout after different time intervals. The effect on casting accuracy using metal ring into a pre heated burnout furnace and using split ring was also carried. The readings obtained were tabulated and subjected to statistical analysis.
RESUMO
The study was conducted in male Kashmiri population to correlate VDO with various facial measurements, since there is no absolute method to determine the VDO for all individuals. The facial landmarks can reliably be used to determine occlusal vertical dimension in edentulous patiens since they are accessible and relatively unchanged throughout the life. Objectives of the study: To correlate various facial measurements with vertical dimension of occlusion in male Kashmiri population.Methods:A total number of 200 dentate male kashmiri subjects in the age group of 20-50 years were selected for this study. The vertical dimension of occlusion was measured between subnasion to menton.DigitalVerniercaliper was used for measuring different facial parameters that were selected for this study. The results were tabulated by employing Student’s independent t-test. Graphically the data was presented by bar diagrams. A P-value of less than 0.05 was considered statistically significant.Results: The results of this study revealed that parameter superior surface of right ear to inferior surface of right ear, center of pupil of right eye to center of pupil of left eye and distance from the outer canthus of the right eye to right ear show no significant difference with VDO in male gender and hence can be correlated positively with VDO in males.
