PURPOSE The aim of this study was to investigate the effect of reinforcing materials on the fracture resistances of glass fiber mesh- and Cr-Co metal mesh-reinforced maxillary complete dentures under fatigue loading. MATERIALS AND METHODS Glass fiber mesh- and Cr-Co mesh-reinforced maxillary complete dentures were fabricated using silicone molds and acrylic resin. A control group was prepared...

PURPOSE Denture survival, or the time between the date of a denture's insertion and the date of its renewal for any clinical reason, was assessed in this retrospective study on 353 complete dentures. The procedures required to prolong the useful time of the study sample-relines, repair of denture base fractures, or replacement of lost artificial teeth-were also evaluated. MATERIALS AND METHOD...

BACKGROUND Despite drawbacks, cold-cured acrylic resin is still the most common material used in denture repair. Zirconia nanoparticles were among the reinforcements added to increase the strength of the resin. The effect on Candida due to the addition of zirconia nanoparticles to the resin has not been investigated. PURPOSE The aim of this study was to evaluate the effect of zirconia nanopar...

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 ...

Background: Sometimes the artificial teeth break or fracture, so then patient asks dentist to repair it. The will send denture be repaired by a dental technician in laboratory. transfer of work is likely pose risk cross infection (for example: AIDS, hepatitis, tuberculosis, pneumonia and herpes. Objective: To knowledge technology dentistry based on community needs objectively obtain strong foun...

PURPOSE Fractures in acrylic resin dentures occur quite often in the practice of prosthodontics. A durable repairing system for denture base fracture is desired to avoid recurrent fracture. The purpose of this study was to evaluate the fracture force, deflection, and toughness of a heat-polymerized denture base resin repaired with autopolymerized resin alone (C), visible light-polymerizing resi...

There are several benefits in using adhesive technique in removable prosthodontics as well as fixed prosthodontics. Previous studies have examined denture-base surface treatments that improve bond strength between a denture base resin and autopolymerizing repair resin. Dichloromethane and ethyl acetate are organic solvents that swell the denture base surface, thereby permitting diffusion of the...

STATEMENT OF PROBLEM Fracture of a repaired denture base often occurs at the junction of the base and repair materials rather than within these materials. PURPOSE The purpose of the study was to evaluate the shear bond strengths of 4 denture base acrylic resins following the use of 3 chemical solvents and to examine treated acrylic resin surfaces under a field emission scanning electron micro...
