The influence of tongue mobility on children's performance in computer games that depend on lingual movements.

Background: Alteration in tongue mobility requires rehabilitation work through oral motor exercises. These exercises can be integrated with computer games to increase the patient's motivation during treatment.

Objective: To investigate the influence of tongue mobility on children's motor performance in a computer game reliant on lingual movements.

Microfluidics and organ-on-a-chip technologies: A systematic review of the methods used to mimic bone marrow.

Bone marrow (BM) is an organ responsible for crucial processes in living organs, e. g., hematopoiesis.

Maxillary suture expansion: A mouse model to explore the molecular effects of mechanically-induced bone remodeling.

The aim of this study was to analyze the effect of rapid maxillary expansion (RME) on hard tissues. Opening loops bonded to the first and second maxillary molars on both sides were used to apply distracting forces of 0.28 N, 0.

The influence of tongue strength on children's performance in computer games reliant on lingual force generation.

Oral motor exercises, for recovering tongue strength, can be integrated with computer games to increase motivation, especially for treatments in children. The aim of this study was to investigate the influence of tongue strength on motor performance in computer games reliant on lingual force generation. An observational study was carried out at a speech-language pathology outpatient university clinic.

A new method for tongue rehabilitation with computer games: Pilot study.

Background: Lingual exercises are commonly used in clinical practice for swallowing rehabilitation. Associating lingual exercises with computer games increases motivation, which influences tongue motor performance.

Objective: To investigate the effects of tongue movement direction; resistance force level; repetition number; sustained tongue contraction duration; age and gender on tongue motor performance in healthy adults using computer games.

Non-invasive methods of computer vision in the posture evaluation of adolescent idiopathic scoliosis.

Purpose: Reviewing techniques for non-invasive postural evaluation of adolescent idiopathic scoliosis (AIS) based on information extraction from images based on computer methods.

Methods: The Scopus, Web of Science, MEDLINE, ScieLo and PubMed databases were used, for the period 2011-2015.

Results: 131 articles were found based on keyword of which 15 articles met the established eligibility criteria.

Stress distribution in a premolar 3D model with anisotropic and isotropic enamel.

The aim of this study was to compare the areas of stress concentration in a three-dimensional (3D) premolar tooth model with anisotropic or isotropic enamel using the finite element method. A computed tomography was imported to an image processing program to create the tooth model which was exported to a 3D modeling program. The mechanical properties and loading conditions were prescribed in Abaqus.

Theoretical distribution of load in the radius and ulna carpal joint.

Purpose: The purpose of this study is to validate a model for the analysis of the load distribution through the wrist joint, subjected to forces on the axes of the metacarpals from distal to proximal for two different mesh densities.

Method: To this end, the Rigid Body Spring Model (RBSM) method was used on a three-dimensional model of the wrist joint, simulating the conditions when making a grip handle. The cartilage and ligaments were simulated as springs acting under compression and tension, respectively, while the bones were considered as rigid bodies.

MAXIMUM PROTRUSIVE TONGUE FORCE IN HEALTHY YOUNG ADULTS.

In clinical speech-language pathology practice, tongue force is usually evaluated qualitatively. Perception and practical experience are used to classify this force. The Biomechanical Engineering Group from the Federal University of Minas Gerais developed an instrument to quantify tongue force.

Evaluation of the force applied by the tongue and lip on the maxillary central incisor tooth.

Purpose: To describe the development and testing of a system that measures forces exerted by the tongue and upper lip on a tooth during rest and during swallowing.

Methods: Twenty-eight subjects, aged 19-31 years (mean: 23.2 years) were submitted to measurement of forces exerted by the upper lip and tongue on the maxillary right central incisor tooth.

Mechanical behavior of three nickel-titanium rotary files: A comparison of numerical simulation with bending and torsion tests.

Aim: To assess the flexibility and torsional stiffness of three nickel-titanium rotary instruments by finite element analysis and compare the numerical results with the experiment.

Methodology: Mtwo (VDW, Munich, Germany) and RaCe (FKG Dentaire, La-Chaux-de-Fonds, Switzerland) size 25, .06 taper (0.

Comparison of the mechanical behavior between controlled memory and superelastic nickel-titanium files via finite element analysis.

Introduction: The aim of this study was to evaluate the flexibility and torsional stiffness of a controlled memory (CM) nickel-titanium (NiTi) file and compare its mechanical responses with those of a superelastic NiTi file with the same geometry using finite element simulation.

Methods: A commercially available instrument with a tip size of 30 and a 0.06 taper was selected for this study.

Quantitative evaluation of tongue protrusion force.

The tongue plays an important role in the functions of speech, mastication, swallowing, and breathing. The tongue helps in the maintenance of proper dental alignment and arch stability. Adequate strength is essential for the tongue to perform these tasks.

Determination of tangential and normal components of oral forces.

Oral forces applied to human teeth during biting and mastication are normally described in the literature only in terms of their axial components. The purpose of this study was to fully determine the spatial characteristics of the oral resultant force - its normal and tangential components - for a given individual. A load cell was especially manufactured to measure oral force and was temporarily implanted as a prosthetic device in the dental arch of a volunteer, replacing his missing upper first molar.

Abfraction and anisotropy--effects of prism orientation on stress distribution.

This work discusses the effect of enamel anisotropy in the stress concentration at the cement-enamel junction (CEJ), a probable cause of fracture in enamel leading to abfraction. Usual simplifications when developing computer models in dentistry are to consider enamel isotropic, or that the direction of the prisms is orthogonal to either the dentine-enamel interface or the tooth outer surface. In this paper, a more refined model for the material behavior is described, based on laboratory observation and on the work of Fernandes and Chevitarese.
