This study evaluated the effect of denture base polymer type (heat- and microwave-polymerized), ridge lap surface treatment (with and without methyl methacrylate-MMA etching) and thermocycling on the microtensile bond strength (microTBS) of Biotone acrylic teeth. Flat-ground, ridge-lap surface of posterior artificial teeth were bonded to cylinders of each denture base resin, resulting in the fo...

BACKGROUND/AIM Acrylic-based resins are intensively used in dentistry practice as restorative or denture-base materials. The purpose of this study was to analyze the surface structure of denture base resins and the amount of released potentially toxic substances (PTS) immediately upon polymerization and incubation in different types of artificial saliva. METHODS Storage of acrylic samples in ...

objective: an immediate complete denture is fabricated before the extraction of all teeth. it has several advantages such as preservation of esthetics, muscular tone, normal speech and reduction of post-operative pain. this report describes a method of using patient’s current fixed partial denture (fpd) for single-appointment construction of interim immediate denture.   case: we used patient’s ...

Introduction. Biologic, physioliogic and mechanical principles need to be considered and carefully coordinated in the establishment of the total denture design and occlusion. The aim of the authors is to share their experience with total denture treatment by patients, edentulous more than 6 years, using the method of intraoral registration of the position of the lower jaw by Gerber and arrangin...

BACKGROUND Fractures of acrylic resin dentures are a common occurrence in clinical dentistry. The denture may be fractured accidentally when dropped or while in service in the mouth due to flexural fatigue. OBJECTIVES The aim of this study was to compare the elastic modulus and the flexural strength between two heat-cured acrylic resins used in denture bases: a high-impact resin (Lucitone 199...

The objective of this study was to present a systematized review of different methods used to evaluate the masticatory efficiency in conventional complete denture wearers. A survey was conducted in the databases PubMed, Scopus, and Cochrane, seeking scientific articles according to the previously selected terms: "Masticatory performance", "Masticatory efficiency" and "Chewing ability complete d...

The purpose of this study was to investigate the retention force of complete palate coverage and palate-less dentures made with three polymerization systems (DS system, SR-Ivocap system, microwave polymerization system) in vitro. The retention force between each denture and a polyurethane model by intervening artificial saliva was measured using a tensile tester. In addition, discrepancies betw...
