Flexural strength of the joint between glass-infiltrated alumina frames and the alumina-magnesia modifier.
PURPOSE The purpose of the present study was to evaluate the flexural strength of the joint between glass-infiltrated alumina frames and the experimental adjusting agent (MA modifier) that contains alumina and magnesia. METHODS A commercially available adjusting agent (Optimizer), a slurry of alumina powder (Alumina modifier), and a bulk specimen (joint-free alumina) were used as controls. Be...
متن کاملReply to Comment on: Flexural Strength by Fractography in Modern Brittle Materials
WE thank Mecholsky et al. 1 for their intense interest in our paper and their appreciation of the great importance and novelty of our results. We are also grateful for this opportunity to place our findings in a more comprehensive context to better discuss their comments. Orr is normally credited with developing the now commonly used equation relating the strength of brittle materials to the mi...
متن کاملInfluence of nano alumina coating on the flexural bond strength between zirconia and resin cement
PURPOSE The purpose of this in vitro study is to examine the effects of a nano-structured alumina coating on the adhesion between resin cements and zirconia ceramics using a four-point bending test. MATERIALS AND METHODS 100 pairs of zirconium bar specimens were prepared with dimensions of 25 mm × 2 mm × 5 mm and cementation surfaces of 5 mm × 2 mm. The samples were divided into 5 groups of 2...
متن کاملWear and flexural strength comparisons of alumina/feldspar resin infiltrated dental composites.
INTRODUCTION Incorporating a feldspar chemical bond between alumina filler particles is expected to increase the wear-resistant and flexural strength properties. AIMS AND OBJECTIVES An investigation was carried out to evaluate the influence of the feldspar chemical bonding between alumina filler particles on wear and flexural strength of experimental alumina/feldspar dental composites. It was...
متن کاملFlexural modulus, flexural strength, and stiffness of fiber-reinforced posts.
BACKGROUND The radiopacity degree of posts is not enough for adequate visualization during radiographic analyses. Glass fiber post with stainless steel reinforcement has been fabricated in an attempt to overcome this limitation. AIM This study was designed to determine the influence of this metal reinforcement on the post mechanical properties. MATERIALS AND METHODS This study evaluated fle...
