VERIFICATION OF BEHAVIOUR OF HUMAN ENAMEL FOR FRACTURE TOUGHNESS DETERMINATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Enamel is the hardest biological tissue in the human body because of its structureand composition. The structure of interlocking rods enables this biomaterial to resist the stresses of mastication. Unfortunately, enamel ...
NUMERICAL SIMULATIONS OF STATIC STRENGTH OF NOVEL DENTAL IMPLANTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
It is important to know the mechanical and micromechanical characteristics of conventional dental implants in order to design and develop novel dental implants and surface treatments that ensure a good biomechanical stability ...
NUMERICAL AND MECHANICAL ANALYSES OF A 3D-PRINTED TITANIUM TRABECULAR DENTAL IMPLANT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
The main focus of this paper is to investigate and describe a novel biomaterial structure. The trabecular structure has only recently been recognized as a viable alternative for prostheses and implants and seems to have ...
GEOMETRY AND MECHANICAL PROPERTIES OF A 3D-PRINTED TITANIUM MICROSTRUCTURE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Construction applications sometimes require use of a material other than construction steel or concrete – mainly in cases, where strength to weight ratio needs to be considered. A suitable solution to this problem are ...
Mesh generation and mechanical tests of basic element cells of porous structures
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
Advanced porous structures are novel, emerging materials with a broad range of applicability but a rather difficult means of design and manufacturing. The advent and availability of the additive manufacturing industry in ...
NUMERICAL COMPARISON OF TRANSGINGIVAL AND SUBGINGIVAL DENTAL IMPLANTS IN REGARD TO THEIR STRESS DISTRIBUTIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
Most modern dental implants differentiate in regard to the fixation of the abutment into two main categories - the external or internal hexagon or octagon. We performed mechanical tests according to the ČSN EN ISO 14801 ...
DENSITOMETRY-BASED FEM SIMULATIONS OF NOVEL POROUS IMPLANTS AND CORRESPONDING STRESS DISTRIBUTION AT THE PERI-IMPLANT AREA
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
The presented work focuses on determining the stress distribution at the peri-implant area around dental implants. A numerical analysis simulating the conditions of chewing food has been performed on a FEM model. This model ...
MECHANICAL TESTING AND NUMERICAL MODELLING OF POROUS STRUCTURES IMPROVING OSEINTEGRATION OF IMPLANTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
Implants, such as dental, are ordinary devices in medical care nowadays, even though they are quite expensive. In the present study, the use of trabecular and gyroid structures as external layer of implants is examined. ...
EVALUATION OF MICROMECHANICAL PROPERTIES OF CARBON FIBER FABRIC USING NANOINDETATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
This paper is focused mainly on nanoindentation of carbon fibers. Fibers are in form of carbon fiber fabric that is used in larger research that is focused on reinforcing beams made of glued laminated timber. Knowledge of ...
GEOMETRICAL OPTIMIZATION OF DENTAL IMPLANTS WITH REGARD TO OSSEOINTEGRATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
A newly developed reference dental implant specimen type was subjected to numerical simulations of osseointegration. The goal of these tests was to optimize the geometry of the implant so as to reduce local stress ...
