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 ...
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 ...

Synthesis, reactivity, electrochemical behaviour, and molecular structure of crown ether cyrhetrene complexes
(Elsevier, 2015)
Cyrhetrenyl crown ether complexes [(eta(5)-C5H4CH=N-M)Re(CO)(3)] (where M = 4-benzo-15-crown-5 (3a), 4-benzo-18-crown-6 (3b), 2-methyl-15-crown-5 (3c), or 2-methyl-18-crown-6 (3d)) were synthesised from cyrhetrenylcarboxaldehyde ...
Effect of surface treatment on the retention of zirconia crowns to tooth structure after aging
(2020-01-01)
Objective: To evaluate the effect of different surface treatments on the retention between zirconia crowns and tooth structure after in vitro aging. Materials and methods: Human third molars (n = 44) received crown ...

New crown-ether Dibenzo-18-crown-4 ligand via sequential one-pot reaction
(2021-01-01)
A friendly synthetic rout for a new crown-ether was developed in this short communication. The method in question was able to produce the desirable product in high yields (up to 80%), even after some purification steps. ...
Fracture Strength Of Aged Monolithic And Bilayer Zirconia-based Crowns

Influence of occlusal anatomy on acrylic resin CAD/CAM crowns fracture load and stress distribution
(2021-05-11)
Objectives: This study compared the influence of occlusal anatomy on acrylic CAD/CAM crowns fracture load and stress distribution. The null hypothesis was that there would be no difference between the provisional crowns ...
