Effect of microthread presence and restoration design (screw versus cemented) in dental implant reliability and failure modes

Clinical Oral Implants Research, 2012
AbstractObjectivesThis study evaluated the reliability and failure modes of implants with a microthreaded or smooth design at the crestal region, restored with screwed or cemented crowns. The postulated null hypothesis was that the presence of microthreads in the implant cervical region would not result in different reliability and strength to failure ...

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.

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

Journal of Dentistry, 2018
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).Records from patients who visited five private practices regularly were searched for the presence of active one- and two ...

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 ...

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.

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
