BACKGROUND Although bonding to denture teeth after surface treatment with chemical agents is desirable, there is little information on the use of Visible Light Cure composite resin (VLC) as bonding denture materials. OBJECTIVES To determine the effect of various surface treatments on shear bond strength between Visible Light Cure composite resin and the acrylic denture teeth interface. METH...

The prosthodontist encounters increasing problems in the fabrication of a well functioning complete denture over a resorbed edentulous ridge. The objective of this study was to clinically evaluate the efficacy of the soft acrylic denture compared to conventional one when used to restore a severely resorbed ridge. Both quantitative and qualitative parameters were assessed. Quantitative parameter...

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...

Background: The purpose of this study was to compare and evaluate the effects of metal primer on the shear bond strength of denture base resin to base metal alloy after electrolytic and laser etching. Materials and Methods: A total of 48 cobalt‐chromium (Co‐Cr) alloy specimens were fabricated. The specimens were divided into 6 groups of 8 specimens each. Group I: Sandblasting (control group). G...

This study aimed to set evaluation indicators, i.e., perceptibility and acceptability color difference thresholds, of color stability for acrylic denture base resins for a spectrophotometric assessing method, which offered an alternative to the visual method described in ISO 20795-1:2013. A total of 291 disk specimens 50±1 mm in diameter and 0.5±0.1 mm thick were prepared (ISO 20795-1:2013) and...

OBJECTIVE This study aimed to evaluate the cellular toxicity of two newly-released acrylic resins (Futura Gen and GC Reline Hard) in comparison with the conventional heat-cure resin (Meliodent). MATERIALS AND METHODS Sample discs from each acrylic resin were placed in 24-well culture plates along with L929 mouse fibroblast cell line. A mixture of the RPMI 1640 medium, antibiotics and 10% FBS ...

Mandibular implant-retained overdentures have become the standard of care for patients with mandibular complete edentulism. As part of the treatment, the mandibular implant-retained overdenture may require a metal mesh framework to be incorporated to strengthen the denture and avoid fracture of the prosthesis. Integrating the metal mesh framework as part of the acrylic record base and wax occlu...
