[Mechanical analysis of the denture bases using the photoelastic-coating method. 2. Upper complete denture bases under uniform bending moment load].

Deformation of the anterior teeth and palatal regions on upper complete dentures was investigated using the photoelastic coating method and strain gages. In this experiment, an uniform-moment bending load method was employed to simulate the occlusal situation, and the distribution of strain in epoxy resin, stainless swaged and Co-Cr alloy cast dentures were measured and analyzed. The 030-series reflection polariscope is compact and lightweight with its main components consisting of two polarizer/quarter-wave-plate assemblies attached to a common frame. The highest level of strain was seen in the anterior region of the palate and the low strain was observed in other regions. Differences in strain magnitude of the three dentures were not observed with test at the same point. But, when denture base materials with high flexural rigidity and bending strength were used on the palatal region of the denture base, strain was decreased in the anterior and other regions of the palate. Therefore, dentures using those materials could be effectively reinforced.

Tongue control of upper complete dentures: a clinical hint.

The role of the tongue in aiding upper denture retention is well recognised by clinicians, but this information is not always related to the patient. This paper describes a simple method of diagnosing the problem and training patients to control their maxillary denture during function, particularly when chewing food.

Structural changes for speech improvement in complete upper denture fabrication.

In the absence of any clearly identifiable pathologic condition, the prosthodontic patient demonstrating speech problems after insertion of complete dentures is having difficulty with loss of turbulence, because of the diminution of tactile location skills in speaking, or both. Potential aids to speech improvement are a nonanatomic papilla placed on the oral surface of the denture just posterior to the location of the incisive papilla, a transversely elongated rugae-like papilla at about the same location, a roughened region at that spot, or an identation sufficient for the patient's tongue to identify. The location and effectiveness of such structural changes can be planned and judged with the cooperation of a qualified speech pathologist.

[Basic study on pressure of supporting tissues under upper complete denture].

Through simulation method, the influences of occlusal force loading point, posterior pontics arrangement, palate thickness and denture base material on pressure distribution over supporting tissues under maxillary complete denture were studied. The results were the following: 1. Pressure distribution over supporting tissues showed remarkable variation according to the position of the occlusal force loading point. 2. Pressure on the buccal side of the alveolar ridge was greater in the buccally shifted arrangement of posterior pontics than in the standard and lingually shifted arrangements. 3. Reduced palate resin thickness below normal value increased pressure on the palate midline region. 4. For the standard and lingually shifted arrangements of posterior pontics, pressure on the incisor and palate midline regions is decreased in metal base compared to acrylic resin base. In the buccally shifted arrangement, pressure on buccal side of the alveolar ridge is lesser in metal base than in acrylic resin base.
