Impact sports and bone fractures among adolescents
(2017-12-17)
The objective of the present study was to investigate the effects of different sports on stress fractures among adolescents during a 9-month follow-up period. The sample was composed of 184 adolescents divided into three ...
Modeling the closure behavior of natural fractures in porous media using high aspect ratio interface elements
(2021-01-01)
Many reservoirs consist of fully saturated rock masses containing a very complex natural fracture network. In such cases a decrease in the fracture fluid pressure reduces its aperture due to an increase in the effective ...
Teriparatide for the rapid resolution of delayed healing of atypical fractures associated with long-term bisphosphonate use
(AVES, 2016-06)
Bisphosphonates (BPs) are the most widely used drugs to treat osteoporosis. However, recent reports associated to long-term BPs use with atypical low-impact fractures and prodromal pain. It is estimated that 26% of the ...
Influence of convergence angle of tooth preparation on the fracture resistance of Y-TZP-based all-ceramic restorations
(2013-03-01)
Objective: To investigate the influence of the convergence angle of tooth preparation on the fracture load of Y-TZP-based ceramic (YZ-Vita YZ) substructure (SB) veneered with a feldspathic porcelain (VM9-Vita VM9). Methods: ...
Crown fracture: Failure load, stress distribution, and fractographic analysis
(Elsevier B.V., 2015-09-01)
Statement of problem. The outcomes from load-to-failure tests may not be applicable to clinical situations. Purpose. The purpose of this study was to critically evaluate the efficacy of load-to-failure tests in the ...
Finite element analysis and fracture resistance testing of a new intraradicular post
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2012-07-01)
Objectives: The objective of the present study was to evaluate a prefabricated intraradicular threaded pure titanium post, designed and developed at the Sao Jose dos Campos School of Dentistry - UNESP, Brazil. This new ...

Photoelastic analysis of conventional and locking system for treatment of mandibular angle fractures with a single plate
(2021-04-01)
Background: This photoelastic analysis evaluated stress distribution in different osteosynthesis systems, conventional and locking, used for treatment of mandibular angle fractures with a single plate. Material and Methods: ...
An engineering methodology to assess effects of weld strength mismatch on cleavage fracture toughness using the Weibull stress approach
(SPRINGER, 2010)
This work describes the development of an engineering approach based upon a toughness scaling methodology incorporating the effects of weld strength mismatch on crack-tip driving forces. The approach adopts a nondimensional ...
In Vitro Study of Fracture Load and Fracture Pattern of Ceramic Crowns: A Finite Element and Fractography Analysis
(Wiley-Blackwell, 2011-08-01)
Purpose: This in vitro study investigated the null hypothesis that metal-free crowns induce fracture loads and mechanical behavior similar to metal ceramic systems and to study the fracture pattern of ceramic crowns under ...
