Risk Factors for Failure of Direct Restorations in General Dental Practices
Journal of Dental Research, 2020 The aim of this retrospective noninterventional multicenter practice-based study was to analyze factors influencing the survival of direct restorations. Records from patients who visited 5 private practices regularly were searched for the presence of direct restorations.

Mechanical Failure of Dental Restorations: The Weakest-Link Theory
, 2020 Tooth tissues and many of the dental restorative materials, e.g. ceramics and resin composites, are brittle in nature. It is typical of these materials to show a large variation in their fracture strength. A mechanistic approach which can account for their complex shapes and stress distributions is needed in the design and performance optimization of ...

Dental Materials, 2019 The aim of this retrospective methodology study was to investigate the influence of using different definitions for restoration failure and inclusion criteria on restoration longevity expressed in AFR.EPF from fifteen general dental practices were used for collecting the data for this study. From the EPF, 321,749 composite restorations placed in 52,245

Types of Failures in Porcelain-Fused-to-Metal Dental Restoration
, 2014 Porcelain-fused-to-metal (PFM) restoration is a type of dental prosthesis introduced since the early 1960s. This prosthesis is strong, aesthetically satisfactory, and affordable. This study aims to classify the types of failures observed in PFM prostheses that were constructed in a dental laboratory in Misrata, Libya. Data from six months of laboratory

The failure of amalgam dental restorations due to cyclic fatigue crack growth. [PDF]
Journal of Materials Science: Materials in Medicine, 1999 In this study a restored mandibular molar with different Class II amalgam preparations was examined to analyze the potential for restoration failure attributed to cyclic fatigue crack growth. A finite element analysis was used to determine the stress distribution along the cavo-surface margin which results from occlusal loading of each restoration. The
