Influence of postpolymerization time and atmosphere on the mechanical properties, degree of conversion, and cytotoxicity of denture bases produced by digital light processing. [PDF]
The Journal of prosthetic dentistry (Print), 2023 STATEMENT OF PROBLEM Studies on the effects of postprocessing conditions on the physical properties, degree of conversion (DC), and biocompatibility of denture bases produced by digital light processing are lacking. PURPOSE The purpose of this in vitro

Radiopaque denture base materials technic dentures
Journal of Biomedical Materials Research, 1971AbstractTechnic dentures were made using composite base materials containing 30,40, and 50 weight % of a silance‐treated, readiopaque, powdered glass as the reinforcing filler and poly (methyl methacrylate) as the matrix. Dentures containing no glass were included for comparison.

Colour effect of denture base on denture tooth materials
Journal of Oral Rehabilitation, 1988SummaryA study using a HunterLab colorimeter was conducted to determine the colour effect of denture base materials on denture tooth acrylics.The results show that denture base materials create a measurable change in the chroma of denture tooth acrylics and suggest that optimal shade selection of teeth should include a determination of the background ...

Conversion in denture base polymers
Journal of Biomedical Materials Research, 1982AbstractThe purpose of this investigation was to determine residual monomers, the insoluble gel fraction, and singly reacted dimethacrylate monomers in heat‐polymerized, auto‐polymerized conventional and pourtype denture base materials. Residual monomers were determined by HPLC analysis of tetrahydrofuran extracts of denture base polymers.

The Journal of Prosthetic Dentistry, 1967
Abstract Clear acrylic resin bases were made from impressions made under different amounts of pressure. Occlusal tables were fitted to them so that an arch-form air bag attached to a sphygmomanometer gauge could be used to control the pressures. The effect of the different pressures on the basal seat tissue was recorded.

Creep in denture base polymers
Journal of Dentistry, 1975Abstract Creep behaviour of denture base resins is an important mechanical property that is not evaluated in standard dental materials testing. This paper outlines the development of a compressive creep test based upon a standard hardness testing machine that shows a good correlation to three-point creep behaviour.

Dental Clinics of North America, 1996
A variety of materials have been used in the fabrication of denture bases. The advantages and disadvantages of these materials are discussed. Special emphasis is placed on polymeric material. particularly poly (methyl methacrylate) (PMMA). The chemical basis for formation of PMMA is provided to facilitate understanding.

The distal extension base denture
Dental Update, 2003The distal extension base denture may be indicated in situations in which the edentulous area to be restored is without a terminal abutment tooth. There may be significant challenges in providing a prosthesis with sufficient support and retention to make it comfortable without damaging the intra-oral tissues.
