For over 3 decades and since the preliminary studies on osseointegration, dental implants have been used extensively for the rehabilitation of completely and partially edentulous patients. Dental treatment with implants appears to provide many benefits for the edentulous patient as well as a significant oral function improvement and increased patient satisfaction. Fewer complaints, increased sa...

UNLABELLED Provisional implant restorations are essential tools used to optimize the esthetic outcomes for single-tooth implant restorations. This article describes three groups of available alternatives and the specific options within each group including removable prostheses (interim removable partial denture, vacuum-formed appliance), tooth-supported prostheses (bonded extracted or denture t...

Acrylic processing of waxed-up dentures is considered to be a crucial and technique-sensitive procedure. Polymethylmethacrylate (PMMA) has become the most commonly used material for denture bases since its introduction in 1937. The advantages of PMMA include excellent esthetic properties, adequate strength, low water sorption, low solubility, lack of toxicity, facility of repair, and constructi...

In cases where there are no suitable natural undercuts on the teeth which can be used to provide clasp retention for a partial denture artificial undercuts can be created by the application of a composite filling material. An in-vitro investigation was undertaken to assess the surface integrity of three different composite restorative materials following repeated cycles of movement of cobalt-ch...

This study aimed to evaluate the tensile and transverse bond strength of chairside reline resins (Tokuyama Rebase II, Mild Rebaron LC) to a thermoplastic acrylic resin (Acrytone) used for non metal clasp denture. The results were compared with those of a conventional heat polymerized acrylic resin (Paladent 20) and a thermoplastic polyamide resin (Biotone). The failure sites were examined by sc...

Although different commercial brands of artificial teeth are available in the market, debonding from the denture base is still an issue when rehabilitating edentulous patients with conventional or implant-supported complete dentures. The purpose of this study was to investigate the effect of surface treatments on the bond strength of four artificial teeth brands to a denture base material polym...

The purpose of this study was to investigate the influence of the surface roughness of denture base resin and metal on wettability with water and saliva. Solid specimens were produced using heat-curing denture base resin and Co-Cr alloy. After polymerizing or casting these materials, specimens with four different types of surface roughness were produced by a progressive polishing process using ...

background : denture fracture is an unresolved problem in complete denture prosthodontics. however, the repaired denture often experiences a refracture at the repaired site due to poor transverse strength. hence, this study was conducted to evaluate the effect of joint surface contoursand glass fiber reinforcement on the transverse strength of repaired acrylic resins. materials and methods: a t...

The purpose of this study was to confirm the dimensional accuracy of a newly developed injection pressing method for resin polymerization by making use of the internal electric resistance of resin to determine the optimal timing for resin injection. A new injection pressing polymerization pot with a built-in system to measure the internal electric resistance of resin was used for resin polymeri...
