Comparative study on the tensile bond strength and marginal fit of complete veneer cast metal crowns using various luting agents: An study.

Introduction: Several commercially available luting agents are used to cement the dental restorations such as intra-coronal, extra-coronal, and fixed partial dentures. Tensile bond strength (TBS) and accurate marginal fit are the essential factors to determine the good clinical results in fixed prosthesis. The retentivity of the luting cements is assessed by their adhesive capacity over the tooth surface and metal surface.

Finite element stress analysis on the influence of cuspal angle and superstructure materials in an implant-supported prosthesis.

Purpose: To investigate the effect of superstructure materials and cuspal angle in an implant-supported fixed partial denture.

Materials And Methods: This finite element analysis study was carried out with varying cuspal angulations of 0°, 20° and 33° and superstructure materials. The simulated models were loaded with 300N forces under different axial and non-axial angulations.
