Geometric Modeling and Fatigue Strength Simulation of Bevel Gears with Variable Radius Tooth Root
Jixie chuandong, 2022 Aiming at the problem that most of the teeth root of straight bevel gears adopt fixed radius fillet transition with 0.3 times of modulus， which tends to to cause large bending stress on the tooth root and reduce the service life of bevel gears， a design ...

Tooth Eruption without Roots [PDF]
Journal of Dental Research, 2013 Root development and tooth eruption are very important topics in dentistry. However, they remain among the less-studied and -understood subjects. Root development accompanies rapid tooth eruption, but roots are required for the movement of teeth into the oral cavity. It has been shown that the dental follicle and bone remodeling are essential for tooth

Dental Hypotheses, 2014 Introduction: Trauma, altered tooth germ position and delayed tooth eruption have been hypothesized as possible causes of tooth root dilacerations and flexion, however these anatomical variations appear more commonly associated with posterior teeth and ...

Malformations of the tooth root in humans [PDF]
Frontiers in Physiology, 2015 The most common root malformations in humans arise from either developmental disorders of the root alone or disorders of radicular development as part of a general tooth dysplasia. The aim of this review is to relate the characteristics of these root malformations to potentially disrupted processes involved in radicular morphogenesis.

Gear tooth rooth stress and fillet radii dependence [PDF]
FME Transactions, 2014 Tooth root form and fillet radius have a great influence on gear tooth root strength that is one of the primary subjects of this paper. Special attention is given to analysis on impact of gear tooth fillet radius at the critical cross section on stress ...

Posts and the root-filled tooth [PDF]
British Dental Journal, 2005 It is clear that teeth often require significant reconstruction following root canal treatment. It is also evident that there is an enormous variety of ways that can be used to achieve this. Although there is some debate about the relative contributions of the root filling and coronal restoration to endodontic success, it is agreed that the best ...

Potential of oil-lubricated cylindrical plastic gears
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018 Bending strength of injection molded polyacetal test gears is investigated in back-to-back testing using oil-lubrication. To validate state of the art calculation methods, tooth geometries with a variable number of teeth are investigated, maintaining a ...
