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 ...

Analysis of Factors Contribute to Failure of Dental Restorations and Its Impact on Patient's Life

Journal of Bashir Institute of Health Sciences
Background: Dental restoration focuses on repairing or replacing damaged or missing teeth, but it has a limited lifespan and leads to significant health issues throughout a patient's life. This study analyzed the potential factors contributing to dental restoration failure and its impact on the patient's life.

Influence of the mechanical properties of composites for indirect dental restorations on pattern failure.

Stomatologija, 2007
This study evaluated the fracture pattern of four composites for indirect dental restoration relating to three-point flexural strength, compressive strength and modulus of elasticity (Solidex, Artglass, belleGlass, and Targis). Ten specimens of each composite were tested in a universal testing machine at 0.5 mm/min crosshead speed for flexural strength

Failure Rates of Tooth-Supported Crown Restorations in an Academic Dental Center

Journal of Dental Health and Oral Research
Background: Accurate documentation of tooth-supported crown restoration failures is crucial for assessing dental care quality. At the University of Michigan School of Dentistry, failure rates from Electronic Health Record (EHR) reports were notably low, however, experts in the quality improvement committee suspected underreporting.

Failure loads of all‐ceramic cantilever fixed dental prostheses on post‐restored abutment teeth: influence of the post presence and post position

European Journal of Oral Sciences, 2018
The influence of a fiber post‐restored abutment tooth on the load capability of a three‐unit zirconia framework cantilever fixed dental prosthesis (cFDP) was evaluated after simulated clinical function. Human lower sound premolars (n = 64) were distributed, in equal numbers, to four experimental groups: two vital abutment teeth (group I; control ...
