background and aims. the aim of this study was to compare flexural strength of specimens processed by conventional and injection-molding techniques. materials and methods. conventional pressure-packed pmma was used for conventional pressure-packed and injection-molded pmma was used for injection-molding techniques. after processing, 15 specimens were stored in distilled water at room temperatur...

objective: the aim of this study was to measure and compare the transverse strength and deflection of two acrylic resins. method and materials: a total of 30 samples, with dimensions of 2.5×10×65mm, were prepared with acropars and meliodent acrylic resins according to ada specification no. 12. the specimens were divided into two groups of 15 samples each. a three-point bending test was carried ...

acrylic resin denture bases undergo dimensional changes during polymerization. injection molding techniques are reported to reduce these changes and thereby improve physical properties of denture bases. the aim of this study was to compare dimensional changes of specimens processed by conventional and injection-molding techniques.sr-ivocap triplex hot resin was used for conventional pressure-pa...

background and aims: we aimed to assess the bond strength of composite resin to three pulp capping biomaterials; proroot mineral trioxide aggregate (pmta), root mta (rmta) and calcium enriched mixture (cem), using three bonding systems [a total etch (single bond) and two self-etch systems (protect bond and se bond)]. materials and methods: ninety acrylic moulds containing a 6×2 mm hole were div...

UNLABELLED Denture fractures are common in daily practice, causing inconvenience to the patient and to the dentists. Denture repairs should have adequate strength, dimensional stability and color match, and should be easily and quickly performed as well as relatively inexpensive. OBJECTIVE The aim of this study was to evaluate the flexural strength of acrylic resin repairs processed by differ...

Purpose: The objective of the research was to investigate dimensional accuracy concerning denture teeth deviation and vertical changes for three-dimensional printed, monolithic dentures relative heat-cured, acrylic resin dentures. Materials methods: A waxed-up reference maxillary constructed on an educational master cast, then duplicated produce ten simulated planned virtual designed by subtrac...

Background: Tooth loss has a negative impact on person's quality of life such as pain, dissatisfaction with appearance and poor speech ability. Loss teeth either partially or completely can be treated using dentures. One the most commonly used dentures is polymethyl methacrylate. Acrylic resin advantages good aesthetics disadvantages absorb liquids which cause dimensional changes. Continuous us...
