Palatal Vault Depth Influence on Acrylic Denture Base Resins : An invitro comparative study

Edentulism is a matter of great concern to the majority of people and their replacement by artificial substitute, such as denture is vital to the continuance of normal life. One of the requirements of the denture is its ability to function for a minimum required period. Complete dentures often fracture during normal masticatory function. The reason could be due to the shape of the palate, i.e. deep, medium or shallow palatal vault. Therefore the aim of the study was to determine the effect of the flexural strength on denture bases fabricated on shallow, medium and deep palatal vault depths. Also a comparison was drawn between the flexural strength of high impact heat cure resin and regular heat cure resin, based on the depth of the palate.
