Influence of incorporation of ZrO2 nanoparticles on the repair strength of polymethyl methacrylate denture bases
BACKGROUND Repeated fracture of the denture base is a common problem in prosthodontics, and it represents a nuisance and a time sink for the clinician. Therefore, the possibility of increasing repair strength using new reinforcement materials is of great interest to prosthodontists. AIM OF THE STUDY This study aimed to evaluate the effects of incorporation of zirconia nanoparticles (nano-ZrO2...
متن کاملEffect of repair resin type and surface treatment on the repair strength of polyamide denture base resin.
The purpose of the present study was to evaluate the effects of different repair resins and surface treatments on the repair strength of a polyamide denture base material. Polyamide resin specimens were prepared and divided into nine groups according to the surface treatments and repair materials. The flexural strengths were measured with a 3-point bending test. Data were analyzed with a 2-way ...
متن کاملBond strength durability of a resin composite on a reinforced ceramic using various repair systems.
OBJECTIVES This study compared the durability of repair bond strength of a resin composite to a reinforced ceramic after three repair systems. METHODS Alumina-reinforced feldspathic ceramic blocks (Vitadur-alpha) (N=30) were randomly divided into three groups according to the repair method: PR-Porcelain Repair Kit (Bisco) [etching with 9.5% hydrofluoric acid+silanization+adhesive]; CJ-CoJet R...
متن کاملEffects of Aging on Compressive Strength of Two Resin-Reinforced Glass Ionomers: An In-Vitro Study
Background and Aim: Although the physical properties of modern glass ionomers have been extensively reported, few studies have examined how these parameters change with age. This experimental study aimed to investigate the effect of aging on the compressive strength of resin-reinforced glass ionomers. Material and Methods: Two glass ionomers (Fuji IX GP Fast, GC, Japan, and Ketac Universal, 3M,...
متن کاملShear Bond Strength of Denture Repair with Autopolymerizing Acrylic Resin Influenced by Three Surface Treatments
The repaired denture base material fractures at the interface of base and repair material. This study evaluated the effect of different chemical treatment of the surfaces on the shear bond strength of conventional heat-cured resin repaired with autopolymerized acrylic resin. The specimens were divided into four groups, 30 specimens each according to surface treatment by chemical etchants Group ...
