Journal ArticleDOI
Holographic determination of centers of rotation produced by orthodontic forces
TL;DR: This in vitro study is designed to establish the required force system applied on the crown of a maxillary incisor that would produce different centers of rotation, as in lingual tipping, translation, and root movement.
Journal ArticleDOI
Force production in the primate masticatory system: electromyographic tests of biomechanical hypotheses☆
TL;DR: The activity of the superficial masseter and anterior temporalis muscles in humans was quantified during high magnitude bite force production at points along the tooth row and indicate that there are substantial changes in muscle activity with bite point, and that the standard lever model is therefore an incomplete description of masticatory force production.
Journal ArticleDOI
Biomechanics of cross‐sectional size and shape in the hominoid mandibular corpus
TL;DR: The shape of the Paranthropus corpora indicates that the mechanical design of the robust australopithecine mandible is fundamentally distinct from that of modern hominoids in terms of its ability to resist transverse bending and torsion.
Journal ArticleDOI
Photoelastic stress patterns produced by implant-retained overdentures☆☆☆★★★♢
Robert Kenney,Mark W. Richards +1 more
TL;DR: Within the limits of this study, ball/O-ring attachments transferred less stress to implants than the bar-clip attachments when the photoelastic model was subjected to a posterior vertical load.
Journal ArticleDOI
Photoelastic analysis of stress transfer by endodontically treated teeth to the supporting structure using different restorative techniques
TL;DR: Findings indicate that distribution and patterns of stresses vary depending on the direction of the loads and the nature of the involved restorative procedures.

Photoelasticity as a Research Technique for Analyzing Stresses in Dental Structures
D.B. Mahler,Floyd A. Peyton +1 more
TL;DR: Since both the design and size of dental restorations are extremely limited by the biologic aspects of tooth structure, an exacting analysis is the only solution to the determination of an optimum structural configuration.

Effect of Excessive Occlusal Forces upon the Pathway of Gingival Inflammation in Humans
Irving Glickman,Jerome B. Smulow +1 more
TL;DR: By altering theperiodontal tissues and the pathway of gingival inflammation, excessive occlusal forces, particularly pressure, could be a factor in the etiology of infrabony pockets and angular bone resorption in periodontal disease.

A Study of Stress Pattern Variations in Class Ii Cavity Restorations as a Result of Different Cavity Designs
TL;DR: It was found that side retention grooves placed in the proximal box portion of the cavity preparation and rounding and sloping the pulpal wall were the most beneficial in increasing the resistance of the silver amalgam restoration to fracture.
Journal ArticleDOI
A preliminary report of photoelastic tests of strain patterns within jacket crowns
TL;DR: If a large plastic prototype of a jacket was loaded on an appropriate core and then sectioned, it would be possible by view ing the sections under polarized light to find the precise regions of detrimental strains and certain changes in the shape of the core could then be made to reduce these strains and thus reduce theence of fracture of jacket crowns.
