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 ...

Longevity of posterior dental restorations and reasons for failure
European Journal of Oral Sciences, 2012Tooth‐coloured restorative materials are being used increasingly more often in Class II preparations in permanent teeth. Using a practice‐based study design, we aimed to assess the survival time of Class II restorations and to identify factors relevant to their longevity.

Failure mode of dental restorative materials under Hertzian indentation
Dental Materials, 2007To explore the application of Hertzian indentation testing to amalgam and GIC; study the failure behavior of the bi-layer structure of each material on a relatively soft substrate; and investigate the effect of thickness.Amalgam (Lojic+, SDI, Bayswater, Australia) and ceramic-reinforced GIC (Advanced Healthcare, Tonbridge, UK) discs, 10 mm diameter ...

Mechanical Failure of Dental Restorations: The Weakest-Link Theory
2020Tooth 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 ...

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, 2011Failure 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.

Types of Failures in Porcelain-Fused-to-Metal Dental Restoration
2015Porcelain-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

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 ...
