The Differences Between Three Performance Measures on Dental Restorations, Clinical Success, Survival and Failure: A Matter of Perspective

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

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 ...

Types of Failures in Porcelain-Fused-to-Metal Dental Restoration

2015
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

Comparison of shear and microtensile failure stresses in the repair of dental composite restorations

2011 2nd International Conference on Instrumentation, Communications, Information Technology, and Biomedical Engineering, 2011
Failure of dental composite restorations frequently occurs. To preserve tooth structure, repair of existing restorations can be done by relayering (composite-to-composite-bonding). This study compares shear and microtensile failure in composite-to-composite-bonding.

Dental Restoration Longevity: Survival Functions and Statistical Indices in Low and High Failure Rate Groups

Community Dentistry and Oral Epidemiology, 1988
Abstract A group of 71 patients was examined to determine the longevity of restorations placed at the University of North Carolina School of Dentistry. Patients with an overall restorations failure rate of equal to or greater than 40 per 1000 restoration‐yr were categorized as having a “high failure rate” and those below that were considered “low ...

A retrospective cross-sectional study of early patient-reported failures of direct restorations placed in a primary dental care setting

British Dental Journal, 2021
Introduction A retrospective cross-sectional study of early patient-reported failures of restorations was initiated to understand the reasons and factors associated with early failure. Early patient-reported failures are defined as restorations requiring replacement within three months of placement.Aim To investigate if restorative material placed or ...

Risk factors for failure of class V restorations of carious cervical lesions in general dental practices

Journal of Dentistry, 2018
OBJECTIVES The aim of this retrospective, non-interventional, multi-center, practice-based study was to analyze factors influencing the survival of restorative treatments of one- and two-surface active cervical (root) caries lesions (CCLs). METHODS Records from patients who visited five private practices regularly were searched for the presence of ...
