The aim of the study was to determine the effect of the flexural strength on denture bases fabricated on different palatal vault depths. Also, to compare the flexural strength of high impact heat cure resin with regular heat cure resin denture bases. Edentulous casts with deep, medium and shallow palatal vault depth were selected. Three different moulds were made in silicone duplicating materia...

Extreme resorption of edentulous maxilla may cause difficulty during fabrication of a maxillary complete denture. Increased inter-ridge distance often creates a clinical problem due to heavy-weighted maxillary prosthesis. This article elaborates an alternative approach for hollowing a maxillary complete denture. It utilizes a clear template of the trial denture facilitating the creation of a ge...

PURPOSE We surveyed youths and denture wearers to evaluate the feeling of oral dryness. In the denture wearers group, we evaluated the association between dentures and feeling of oral dryness. MATERIALS AND METHODS The survey was performed in 100 denture wearers (mean age, 66.2+/-8.6 years) who visited our department from June to October 2003. A similar survey was performed in 50 youths (mean...

Long-term soft denture lining (LTSDL) materials are used to alleviate the trauma associated with wearing complete dentures. Despite their established clinical efficacy, the use of LTSDLs has been limited due to the unfavorable effects of the oral environment on some of their mechanical and performance characteristics. The unresolved issue of LTSDL colonization by Candida albicans is particularl...

Maxillary denture bases having three types of palatal vault shapes –shallow, medium and deep– were used in this study. The reinforced materials used were the round metal wire-diametered in 1.50 mm, semirounded metal wire -thickened 1.50×0.75 mmand the stainless steel mesh (70mmx2.5mmx2.5mm). A total of 132 acrylic denture bases were prepared with the conventional method from heat-cured acrylic ...

The amount of strain in functioning dentures (and the resultant tissue distortion) caused by using various posterior teeth of different occlusal configurations has not been satisfactorily investigated. In an attempt to determine which occlusal form produces the greater overall strain and the greater strain per unit pressure applied, interchangeable posterior teeth (zero degree and anatomic) a w...

The purpose of this investigation was to analyze the accuracy of digitally fabricated wax trial dentures and conventionally finalized complete dentures in comparison to a surface tessellation language (STL)-dataset. A generated data set for the denture bases and the tooth sockets was used, converted into STL-format, and saved as reference. Five mandibular and 5 maxillary denture bases were mill...

Characterization is a process in which the character or collective qualities of person are introduced complete denture either by modification teeth bases ,to make it more natural for that , characterization necessary to give leaf like appearance appear this case report reviews various principles an effort produce appearing denture.

Introduction: Few researches have been conducted researches on the influence of the type of dental stone used for fabrication of casts on the adaptation of denture bases. The purpose of this study was to compare the effect of two types of stone casts on the accuracy of fit in complete denture bases. Methods: Using sixty fully replicated master casts obtained by duplicating a metal die represent...

UNLABELLED The denture bases made by using polymethyl methacrylates of Acrylic resin family have excellent physical properties, simple to process and easy to reline, rebase and repair. One of the inherent disadvantages of this material is the liability to break during function. The strength assessment of acrylic resins have been made generally by transverse defection tests. AIM To evaluate th...
