Disease relevance of Denture Bases

• The effect of streptozotocin-induced diabetes mellitus on histopathological changes in tissues bearing masticatory pressure exerted through an experimental denture base has been studied in animal specimens [1].
• There is insufficient knowledge of the mechanical properties of hypoallergenic denture base materials to warrant their use in place of PMMA-based acrylic resins for patients with allergic reaction to MMA [2].
• This study compared the dimensional stability and dehydration of a thermoplastic polycarbonate denture base resin with two conventional polymethyl methacrylate denture base resins [3].
• From the results observed in this study, a high correlation was observed between the histopathological changes under a denture base and the intensity of the occlusal pressure, and the possibility of the existence of the threshold for bone resorption induced by occlusal pressure was suggested [4].

High impact information on Denture Bases

• The analysis of cigarette smoke solutions and immersion solutions of denture-base acrylic resins showed that ng-micrograms/microliter levels of formaldehyde and acetaldehyde were contained in cigarette smoke and leached from dental resins [5].
• The effect of cross-linking agents on the impact resistance of a linear poly(methyl methacrylate) denture-base polymer [6].
• It seems likely that by replacing EGDMA in denture-base resins with a cross-linking agent such as PEG 600 DMA, one could use a higher concentration with a consequent improvement in solvent resistance [6].
• Specimens of the studied materials (E-glass, denture base polymer, titanium, cobalt-chromium alloy, gold alloy, and grained feldspar ceramic) were incubated in a suspension of S. mutans, allowing initial adhesion to occur [7].
• The effect of pure alcohol as well as several alcoholic drinks on the static and dynamic strength and surface quality of denture base poly (methyl methacrylate) was investigated [8].

Biological context of Denture Bases

• OBJECTIVES: This study investigated the effect of microwave disinfection (650W/6 min) on the flexural strength of five hard chairside reline resins (Kooliner, Duraliner II, Tokuso Rebase Fast, Ufi Gel Hard, New Truliner) and one denture base resin (Lucitone 550) [9].

Anatomical context of Denture Bases

• A strong biologic relationship was demonstrated between the length of the cranial base of blacks and their denture bases, the palatal, and occlusal planes [10].
• The purpose of this study was to test the efficacy of utilizing implants underneath distal free-end denture bases to establish a stable occlusal support for extreme shortened dental arches (ESDA) [11].
• A space between the denture base and a root cap can effectively control the distribution ratio of occlusal force to abutment teeth and an alveolar ridge [12].
• This article describes a selective-pressure impression technique for the edentulous maxilla that is intended to compensate for the polymerization shrinkage of heat-polymerized polymethyl methacrylate resin and provides improved palatal adaptation of the definitive denture base [13].
• The experimental denture base, which was designed to load initial continuous pressure of 0.0, 1.0, 10.0 or 20.0 kPa to the denture supporting tissue, was applied to the molar region of hard palate of streptozotocin-induced diabetic rats [14].

Associations of Denture Bases with chemical compounds

• In vitro studies into the release of chlorhexidine acetate, prednisolone sodium phosphate, and prednisolone alcohol from cold cure denture base acrylic [15].
• Eight particulate radiopaque glasses were prepared and incorporated into poly(methyl methacrylate) denture base material, and the properties of the resultant composites were measured [16].
• An investigation was carried out into the release of chlorhexidine acetate, prednisolone sodium phosphate, and prednisolone alcohol from a cold cured acrylic denture base material [15].
• Residual monomers were determined by HPLC analysis of tetrahydrofuran extracts of denture base polymers [17].
• METHODS: Three-dimensional finite element models of a denture-base were studied, which consisted of acrylic occlusal rims with different heights and metal frameworks [18].

Gene context of Denture Bases

• This study evaluated the wetting properties of different artificial saliva formulations that were mucin-based, carboxymethylcellulose-based, and concentrated ion-based on poly(methyl methacrylate) denture base resin, and compared these properties with natural saliva [19].
• In the light of this, SEN specimens of heat-cured denture-base PMMA were saturated in a range of liquids and extended to failure at chewing speed [20].
• MATERIALS AND METHODS: Five soft lining materials, Clearfit LC, two plasticised acrylics (Super-soft, Soften) and two silicones (Molloplast B, Sofreliner) were used to determine water sorption, solubility, staining resistance, Shore A hardness and shear bond strength to denture base [21].
• Clinical applications of visible light-cured resin in maxillofacial prosthetics. Part I: Denture base and reline material [22].
• The use of Triad VLP reline material to repair Triad VLP denture base resin produced the highest strengths [23].

Analytical, diagnostic and therapeutic context of Denture Bases

• Gas chromatography (GC) was investigated for the determination of residual methyl methacrylate (MMA) in heat-processed poly(methyl methacrylate) (PMMA) denture base material emphasizing recovery and validation [24].
• Flow injection analysis of formaldehyde leached from denture-base acrylic resins [25].
• Acrylic resin is widely used as a denture base material, but the upper complete denture fails often during use [26].
• Recently developed adhesive denture base resins which contain the monomer 4-methacryloxyethyl trimellitate anhydride can create a chemical bond to partial denture alloys [27].
• Occlusal force applied to the denture base and forces transmitted to the retainers were measured on several separate occasions from the insertion of new dentures to about 4 months after [28].
