Tilted and Short Implants Supporting Fixed Prosthesis in an Atrophic Maxilla: A 3D-FEA Biomechanical Evaluation
(2013-08-07)
Purpose: This study compared the biomechanical behavior of tilted long implant and vertical short implants to support fixed prosthesis in an atrophic maxilla. Materials and Methods: The maxilla model was built based on a ...
Hindlimb unloading producing effects on bone biomechanical properties in mature male rats
(2007-12-01)
Aging is associated with decline in muscle mass and strength and reduced bone density. Age-related bone loss is a primary factor in osteoporosis and all individuals are potential candidates for osteoporosis because bone ...
Detecting early biomechanical effects of zoledronic acid on femurs of osteoporotic female rats
(2012-12-01)
Aim. To investigate the biomechanical effects of zoledronic acid (ZA) on femurs of female osteoporotic rats after follow-up periods of 9 and 12 months. Methods. Eighty female Wistar rats were prospectively assessed. At 60 ...
Lower limb strength is associated with gait biomechanical abnormalities in older female fallers and non-fallers
(2013-06-17)
BACKGROUND: Age-related loss in lower limb strength is related with impaired mobility. However, the association between decreased lower limb strength and gait biomechanical abnormalities is unclear. %In line with this, ...
Low-level laser therapy, at 60 J/cm(2) associated with a Biosilicate (R) increase in bone deposition and indentation biomechanical properties of callus in osteopenic rats
(Spie-soc Photo-optical Instrumentation Engineers, 2011-07-01)
We investigate the effects of a novel bioactive material (Biosilicate (R)) and low-level laser therapy (LLLT), at 60 J/cm(2), on bone-fracture consolidation in osteoporotic rats. Forty female Wistar rats are submitted to ...
The influence of the flexibility of the chair seat on pressure peak and distribution of the contact area in individuals with cerebral palsy during the execution of a task
(2011-07-01)
This study aimed to determine the influence of flexibility of the chair seat surface on the pressure peak and on the contact area during the execution of a task of handling an object on the seated position by individuals ...
Importance of periodontal ligament thickness
(2013-01-01)
This study evaluated whether periodontal ligament (PL) thickness varied with root size and examined the possible influence of this variation on orthodontic mechanics. Measurements were taken of the maxillary left first ...
Stress distribution in implant-supported prosthesis with external and internal implant-abutment connections
(2013-03-01)
Objective. This study aimed to investigate the stress distribution in screwed implant-supported prostheses with different implant-abutment connections by using a photoelastic analysis. Materials and methods. Four photoelastic ...
Avaliação ultraestrutural do colágeno do ligamento colateral medial associado ao ligamento oblíquo da articulaç ão do cotovelo de cão SRD após ensaio de tração
(2005-04-01)
Ultrastructural evaluation of the collagen of the mongrel dog medial collateral ligament associated to the oblique ligament after strain. The present work aimed to observe the disposition of the collagen fibres of the ...
Evaluation of reusable cardboard box designs: Biomechanical and perceptual aspects
(2013-03-01)
Reusable cardboard boxes can be ergonomically designed for internal transportation of dry products in industrial settings. In this study we compared the effects of handling a regular commercial box and two cardboard ...
