This study combines the use of a Tooth Contact Analysis (TCA) model for helical gear pair conjunctions with multifaceted tribological model, implicitly coupled multi-body dynamic system. A reduced order 2-D Elastohydrodynamic Lubricant (EHL) film thickness prediction facilitates estimation viscous and boundary friction Greenwood-Tripp asperity as well lubricated wear methodology. An implicit ap...

introduction: the resistance to fracture of endodontically treated teeth restored with esthetic post systems has not been extensively researched. this in vitro study compared the fracture patterns of endodontically treated teeth with esthetic post systems with different analysis methods. materials and methods: a total of 26 recently extracted human maxillary central incisors were decoronated an...

BACKGROUND The splinting of an implant and tooth is a rational alternative in some clinical situations. The complex biomechanical aspects of a tooth-implant system are derived from the dissimilar mobility between the osseointegrated implant and the tooth. The aim of this study was to analyze the biomechanics in a tooth-implant splinting system for various bone qualities with different occlusal ...

In the current study, ten participants walked for two hours while carrying no load or a 40 kg load. During the second hour, treadmill grade was manipulated between a constant downhill or changing between flat, uphill, and downhill grades. Throughout the prolonged walk, participants performed two cognitive tasks, an auditory go no/go task and a visual target detection task. The main findings wer...

Although growth plate response to mechanical stress has been increasingly studied, our understanding of mechanical modulation of neonatal growth plate is incomplete, especially concerning biochemical changes. This study was designed to explore the cellular and biochemical responses of the cranial base growth plate (CBGP) explant upon cyclic loading. The growth plate with subchondral bone was as...

With the advent of immediate single stage implant placement and immediate prosthesis fabrication, the edentulous patients can today walk out with “Teeth in a day”. Moreover, the refinement of clinical protocols, the application of sound biomechanical principles, improvements in implant design, and the development of new implant surfaces have resulted in the increased use of this procedure. The ...

Contact tracing is a well-established disease control measure that seeks to uncover cases by following chains of infection. This paper examines mathematical models of both single-step and iterative contact tracing schemes and analyses the ability of these procedures to trace core groups and the sensitivity of the intervention to the timescale of tracing. An iterative tracing process is shown to...

introduction: failure of teeth to erupt from gingival tissues at usual developmental time is called delayed tooth eruption (dte). delayed tooth eruption lead to prolonged fixed orthodontic treatment and its eventual complications. the purpose of the present study was to evaluate the effect of laser-assisted (808 nm) surgical uncovering, on the tooth emergence and orthodontic treatment of dte. m...
