Reconstruction of the posterior cruciate ligament (PCL) by a tibial press-fit fixation of the patellar tendon with an accessory bone plug is a promising approach because no foreign materials are required. Until today, there is no data about the biomechanical properties of such press-fit fixations. The aim of this study was to compare the biomechanical qualities of a bone plug tibial inlay techn...

This study aimed to evaluate the stress distribution and mechanical behavior of miniplate designs skeletal anchorage for treatment anterior open bite in adult patients. A complete hemimaxilla, teeth, brackets, transpalatal bar, three miniplates were virtually modeled. I-, Y-, T-shaped installed area alveolar zygomatic crest. The assembly was constricted intrusive forces (2, 4, 6 N) applied maxi...

Reinforcement Learning (Sutton and Barto 1998) is a theoretical framework for optimizing the behavior of artificial agents. The notion that behavior in the natural world is in some sense optimal is explored by areas such as biomechanics and physical anthropology. These fields propose a variety of candidate optimality criteria (?, e.g.,)]eng,cost as possible formulations of the principles underl...

Bone properties and response behavior after static or dynamic activation (loading) are still interesting topics in many fields of the science especially in the biomechanical problems such as bone loss of astronauts in space, osteoporosis, bone remodeling after fracture or remodeling after surgery (endoprosthesis and implants) and in osteointegration. This contribution deals with the relation be...

Periodontitis is one of the most common conditions affecting oral health among adults, posing a great challenge for both patients and also dentists aiming to treat this disease. In severe stages such deterioration supporting tissues, namely periodontal ligaments bone, can occur, which will affect biomechanical behavior therefore longevity survival affected teeth. order be able plan subsequent r...

Using recruitment manoeuvres in acute lung injury remains a controversial issue because no convincing outcome data support their general use, although many physiological studies have demonstrated beneficial effects on lung compliance, end-expiratory lung volume and gas exchange. One of the reasons why physiologically meaningful observations do not translate into clear clinical benefit could be ...

This study aims to assess the biomechanical behavior of alveolar bone surrounding implants over protocol with metal, Polyether ether ketone (PEEK) and Zantex bars, in normal osteoporotic conditions. For simulation, geometric models mandibular arch were designed containing 5 two variables. The first variable is condition - osteoporotic-, second material used bars – PEEK Zantex. Simulation was pe...

Purpose: Considering the influence of horizontal velocity on many biomechanical characteristics of walking, the purpose of this study was to investigate how inter-lower-limbs local and global asymmetry is influenced by changes in walking speed from slow to fast. Methods: Ground reaction force data and trajectory of attached markers of bilateral lower limbs of 15 right leg-dominant able-bodied ...
