Effects of Contact Normal Bond Strength on Brazilian Tensile Strength by Particle Flow Code

Surfactant effects on soil aggregate tensile strength

PEEK surface treatment effects on tensile bond strength to veneering resins.

STATEMENT OF PROBLEM Polyetheretherketone (PEEK) can be used as a framework material for fixed dental prostheses. However, information about the durable bond to veneering resins is still scarce. PURPOSE The purpose of this study was to investigate the effect of chemical treatments of PEEK on tensile bond strength (TBS) to veneering resins with special emphasis on surface free energy (SFE) and...

Over-etching effects on micro-tensile bond strength and failure patterns for two dentin bonding systems.

OBJECTIVES The purpose of this study was to determine (1) the weakest zone of resin-dentin bonds and (2) the relation between bond strength and failure mode to clarify the effect of demineralized dentin. METHODS Human premolars were sectioned to expose the dentin surfaces, and the dentin surfaces were conditioned with phosphoric acid for 15, 60, 120, or 180s. Resin-dentin bonded specimens wer...

Evaluation of Tensile Bond Strength between Dentin and Metallic Copings Using Different Resin Cements

Statement of the Problem: For a successful clinical outcome, luting agents should have a high bond strength. Bond failure is still one of the main reasons of restoration failures. Purpose: The present study was designed to comparatively evaluate the retention of metallic copings using different resin luting cements. Materials and Method: In the present experimental study, 40 intact premolar tee...
