Stem and crown allometry in four congeneric species of dioecious tropical trees
(2016)
Morphological adaptations favor differential use of the space in tropical trees, but the variability in stem and crown allometry can be constrained by phylogenetic and mechanical factors. In addition, dioecious species ...
Multidisciplinary treatment approach for crown fracture and crown-root fracture - a case report
(Blackwell Publishing, 2007-02-01)
The increased incidence of traumatic injuries to anterior teeth is a consequence of leisure activities, where the most common injuries are crown fractures. Treatment of the dental trauma is complex and requires a comprehensive ...
An efficient synthesis of bis(calix[4]arenes), bis(crown ether)-substituted calix[4]arenes, aza-crown calix[4]arenes, and thiaza-crown calix[4]arenes
(2000)
The easy transformation of 5,11,17,23-tetra-tert-butyl-25,27-bis(aminoethoxy)-26,28-dihydroxycalix[4]are ne (2) into 5,11,17,23-tetra-tert-butyl-26,28-dihydroxy-25,27-bis(2-isothiocyanoethoxy)ca lix[4]arene (3) and ...
Influence of Cusp inclination and type of retention on fracture load of implant-supported crowns
(2017-01-01)
There are few informations about the influence of cusp inclination on the fracture strength of implant-supported crowns. The study aimed to evaluate the influence of cusp inclination and retention type on fracture load in ...
Crown size and growing space requirement of common tree species inurban centres, parks, and forests
(Elsevier, 2015)
Tree crown size determines among others tree’s growth, carbon sequestration, shading, filtering of fineair particulates, and risk of wind-breaking. The dependence of crown size on species, resource supply,and tree age ...

Mechanical behavior of conceptual posterior dental crowns with functional elasticity gradient
(Mosher & Linder, Inc, 2019-08-01)
Purpose: To evaluate the biomechanical behavior of monolithic ceramic crowns with functional elasticity gradient. Methods: Using a CAD software, a lower molar received a full-crown preparation (1.5 mm occlusal and axial ...

Effect of Preseating, Screw Access Opening, and Vent Holes on Extrusion of Excess Cement at the Crown-Abutment Margin and Associated Tensile Force for Cement-Retained Implant Restorations
(2016-07)
PURPOSE:
This study sought to (1) compare the effects of crown preseating prior to cementation, (2) determine whether maintenance of screw access openings on titanium abutments and open vent holes on cast crowns affects ...
