Influence of post material and length on endodontically treated incisors with a considerably bone loss
González-Lluch, Carmen; Rodríguez Cervantes, Pablo Jesús; Sancho-Bru, Joaquin L.; Pérez-González, Antonio; Barjau Escribano, Amaya; Forner Navarro, Leopoldo Springer Verlag (2011) -
Interpreting finite element results for brittle materials in endodontic restorations
Pérez-González, Antonio; Iserte-Vilar, Jose L.; González-Lluch, Carmen BioMed Central (2011-06-02)Background: Finite element simulation has been used in last years for analysing the biomechanical performance of post-core restorations in endodontics, but results of these simulations have been interpreted in most of ... -
Máquina para la automatización de la fabricación de probetas de hormigón fresco para el control de calidad en la construcción
Pérez-González, Antonio; Sancho-Bru, Joaquin L.; Sanchis LLopis, Roberto Asociación Española de Ingeniería Mecánica (2008)In this work a new machine is presented for automating sample preparation in the quality control process of concrete structures. The machine is fixed in an industrial vehicle and is energized with its batteries. In the ... -
Mechanical performance of endodontic restorations with prefabricated posts: sensitivity analysis of parameters with a 3D finite element model
González-Lluch, Carmen; Pérez-González, Antonio; Sancho-Bru, Joaquin L.; Rodríguez Cervantes, Pablo Jesús Taylor & Francis (2014-04)Many studies have investigated the effect of different parameters of the endodontically restored tooth on its final strength, using in vitro tests and model simulations. However, the differences in the experimental set-up ... -
Predicting Wrist Joint Angles from the Kinematics of the Arm: Application to the Control of Upper Limb Prostheses
Pérez-González, Antonio; Roda-Casanova, Victor; Sabater, Francisco Javier MDPI (2023-06)Automation of wrist rotations in upper limb prostheses allows simplification of the human–machine interface, reducing the user’s mental load and avoiding compensatory movements. This study explored the possibility of ... -
Premolars restored with posts of different materials: fatigue analysis
Rodríguez Cervantes, Pablo Jesús; Sancho-Bru, Joaquin L.; González-Lluch, Carmen; Pérez-González, Antonio; Barjau Escribano, Amaya; Forner Navarro, Leopoldo The Japanese Society for Dental Materials and Devices (2011-11-30)Previous works studied the effect of the material and the dimensions of the post on the biomechanical performance (fracture strength and stress distribution) of restored teeth, under static loads. The aim of this work was ... -
Scalability of the Muscular Action in a Parametric 3D Model of the Index Finger
Sancho-Bru, Joaquin L.; Vergara, Margarita; Rodríguez Cervantes, Pablo Jesús; Giurintano, David J.; Pérez-González, Antonio Springer Verlag (2008)A method for scaling the muscle action is proposed and used to achieve a 3D inverse dynamic model of the human finger with all its components scalable. This method is based on scaling the PCSA (physiological cross-sectional ... -
Stiffness map of the grasping contact areas of the human hand
Pérez-González, Antonio; Vergara, Margarita; Sancho-Bru, Joaquin L. Elsevier B.V. (2013)The elasticity and damping of the soft tissues of the hand contribute to dexterity while grasping and also help to stabilise the objects in manipulation tasks. Although some previous works have studied the force-displacement ... -
System for the experimental evaluation of anthropomorphic hands. Application to a new 3D-printed prosthetic hand prototype
Llop-Harillo, Immaculada; Pérez-González, Antonio Taylor & Francis (2017)In the present study, we propose a new actuation device and protocol for testing the grasping performance of low-cost 3D-printed hand prototypes. The actuation device is connected to the forearm of a healthy user and allows ... -
The Anthropomorphic Hand Assessment Protocol (AHAP)
Llop-Harillo, Immaculada; Pérez-González, Antonio; Starke, Julia; Asfour, Tamim Elsevier (2019-11)The progress in the development of anthropomorphic hands for robotic and prosthetic applications has not been followed by a parallel development of objective methods to evaluate their performance. The need for benchmarking ... -
Using kinematic reduction for studying grasping postures. An application to power and precision grasp of cylinders
Jarque-Bou, Néstor J; Gracia-Ibáñez, Verónica; Sancho-Bru, Joaquin L.; Vergara, Margarita; Pérez-González, Antonio; Andres-Esperanza, Javier Elsevier (2016)The kinematic analysis of human grasping is challenging because of the high number of degrees of freedom involved. The use of principal component and factorial analyses is proposed in the present study to reduce the hand ... -
Validity of a simple videogrammetric method to measure the movement of all hand segments for clinical purposes
Sancho-Bru, Joaquin L.; Jarque-Bou, Néstor J; Vergara, Margarita; Pérez-González, Antonio SAGE Publications (2014)Hand movement measurement is important in clinical, ergonomics and biomechanical fields. Videogrammetric techniques allow the measurement of hand movement without interfering the natural hand behaviour. However, an ...
