Impact strength of denture base and reline acrylic resins subjected to long-term water immersion
(2011-05-13)
Water may influence the mechanical properties of the acrylic resins. Thus, the effect of water storage on the impact strength (IS) of one denture base (Lucitone 550 - L) and four reline resins (Tokuyama Rebase II - T; ...
Tensile bond strengths of hard chairside reline resins as influenced by water storage
(1999-08-01)
Due to gradual resorption of the edentulous ridge bone, removable prostheses often require denture base relines to improve fit and stability. This research evaluated the bond strength between one heat-cured acrylic resin ...
Maxillary complete denture movement during chewing in mandibular removable partial denture wearers
(Wiley-Blackwell Publishing, Inc, 2009-03-01)
To evaluate the pattern of maxillary complete denture movement during chewing for free-end removable partial dentures (RPD) wearers, compared to maxillary and mandibular complete denture wearers.Eighteen edentulous ...
Measurement of Interfacial Porosity at the Acrylic Resin/Denture Tooth Interface
(Wiley-Blackwell, 2010-01-01)
Purpose: Small pores of almost uniform shape and size are common in polymeric materials; however, significant porosity can weaken a denture base resin and promote staining, harboring of organisms such as Candida albicans, ...
Influence of storage period and effect of different brands of acrylic resin on the dimensional accuracy of the maxillary denture base
(2008-12-01)
The aim of this study was to evaluate the dimensional changes of denture bases made from different resins after different storage periods. For this purpose, 25 sets of plaster models/resin bases were prepared using 4 acrylic ...
Changes in occlusal vertical dimension in microwave processing of complete dentures.
(2002-11-13)
This study investigated the effect of different microwave curing cycles on the changes in occlusal vertical dimension of complete dentures. Four test groups with 12 maxillary dentures each were evaluated. Groups 1, 2 and ...
Effect of microwave disinfection procedures on torsional bond strengths of two hard chairside denture reline materials
(2006-11-01)
Purpose: This study evaluated the potential effects of denture base resin water storage time and an effective denture disinfection method (microwave irradiation at 650 W for 6 minutes) on the torsional bond strength between ...
Effect of disinfectant solutions on a denture base acrylic resin.
(2012-12-01)
The aim of this study was to evaluate the hardness, roughness and mass loss of an acrylic denture base resin after in vitro exposure to four disinfectant solutions. Forty specimens (Clássico, Brazil) were prepared and ...
Unrestricted linear dimensional changes of two hard chairside reline resins and one heat-curing acrylic resin
(1996-12-01)
The selection and use of hard chairside reline resins must be made with regard to dimensional stability, which will influence the accuracy of fit of the denture base. This study compared the dimensional change of two hard ...
Color stability of resins and nylon as denture base material in beverages
(2011-12-01)
Purpose: Staining of prosthodontic materials may result in patient dissatisfaction and additional expense for replacement. This study aimed to determine the color stability of two heat-cured denture base acrylic (Lucitone ...
