  • bone
  • Despite this, if the patient's maximum bite force is recorded in the planning stages, it's possible to control these forces by combining the right number and type of implants, the right positioning to minimise impact, and the right density of bone. (mimetikoss.com)
  • It's well-documented that a patient with a low bite force will often manage a successful implant, in spite of any eating habits or para-functions, and, even on some occasions, with poor anatomical bone structure. (mimetikoss.com)
  • If our calculations are correct, Megapiranha was probably a bone-crushing predator taking bites of anything and everything," she said. (bio-medicine.org)
  • teeth
  • That's thanks to the right combination of biting power plus blunt teeth that were serrated like steak knives, says Erickson. (wuwm.com)
  • And as NPR's Nell Greenfieldboyce reports, scientists now think they know just how hard those teeth could bite. (wuwm.com)
  • When teeth are missing, any loss does not reduce bite force capability. (mimetikoss.com)
  • Bite force is the force produced by the muscles of mastication when the upper jaw & and lower jaw teeth meet in the course of biting or chewing. (medicaljb.com)
  • Besides the force of the bite, Megapiranha paranensis appears to have had teeth capable of shearing through soft tissue the way today's piranhas do, while also being able to pierce thick shells and crack armoring and bones, according to Stephanie Crofts, a University of Washington doctoral student in biology. (bio-medicine.org)
  • The scientists were particularly interested because Megapiranha 's unusual teeth appear to do two things at the same time, one the piranha-like ability to shear soft tissues and the other an ability to bite like the nut-crushing pacu, piranha's close relative. (bio-medicine.org)
  • Natural teeth have a unique sense of occlusal awareness in the control of mastication, force, and control of muscles during swallowing. (pocketdentistry.com)
  • 13 In combination with the periodontal mechanoreceptors (PMRs), afferent information is sent to the brain on the horizontal and vertical forces applied to teeth. (pocketdentistry.com)
  • 1 N), whereas posterior teeth exhibit sensitivity to forces in the range of less than 4 N. (pocketdentistry.com)
  • The posterior teeth in comparison have fewer mechanoreceptors, which results in a lower static and dynamic sensitivity allowing for posterior teeth to accommodate higher forces during mastication. (pocketdentistry.com)
  • pounds
  • What we came up with were bite forces of around 8,000 pounds," says Gregory Erickson of Florida State University. (wuwm.com)

  • Human bites come in at a paltry 200 pounds or so. (wuwm.com)
  • The researchers believe those could have had bite forces up around 18,000 pounds, over twice as high as what T. rex could do. (wuwm.com)
  • PAUL GIGNAC: What we came up with were bite forces of around 8,000 pounds. (wuwm.com)
  • Taking into consideration its size, an ancient relative of piranhas weighing about 20 pounds delivered a bite with a force more fierce than prehistoric whale-eating sharks, the four-ton ocean-dwelling Dunkleosteus terrelli and even Tyrannosaurus rex . (bio-medicine.org)
  • One 2 pound fish delivered a bite with a force of 320 newtons, or about 72 pounds, which is 30 times its body weight. (bio-medicine.org)
  • Based on the 2 pound piranha and other specimens tested in the wild, the scientists calculate that Megapiranha paranensis , which weighed approximately 22 pounds, could have had a bite force anywhere from 1,240 to 4,750 newtons or 280 to 1,070 pounds and possibly more. (bio-medicine.org)
  • muscles
  • The researchers then took what they knew about crocodile jaw muscles and bite forces, and used that information to create detailed 3-D computer models that could reveal T. rex's chomping potential. (wuwm.com)
  • There exists an argument that there could be two chief elements that avert subjects from producing complete maximum bite forces when biting on solid surfaces using full potential of their jaw occlusion muscles. (medicaljb.com)
  • 11 ] suggested that inaccurate estimation of maximum muscle forces (e.g. owing to inaccurate values of muscle fibre length, muscle strength or the failure to consider the effects of pennation in highly pennate muscles) might explain the mismatch they found between predicted and measured bite forces. (royalsocietypublishing.org)
  • To test the bite force of Didelphodon , Abby Vander Linden, a former University of Washington biology research technician at the Burke Museum, CT-scanned the fossils and compared the gaps in reconstructed skulls where jaw muscles would go to present-day mammals with known bite forces. (futurity.org)
  • The black piranha's bite is so powerful in part because of its massive jaw muscles and rope-like tendons that together account for 2 percent of the fish's overall weight, the scientists found. (bio-medicine.org)
  • mammals
  • We propose that observations of such cracking can be used as a diagnostic tool for predicting bite force and inferring tooth function in living and fossil mammals. (nih.gov)
  • As a result, biting kinematics would be congruent with biting behavior reported for their terrestrial ancestors, thus providing additional evidence that raptorial biting is a conserved behavior even in recently aquatic mammals. (biologists.org)
  • anterior
  • To compare the efficacy of three-dimensional (3D) miniplates with standard miniplates in the osteosynthesis of anterior mandibular fractures on the basis of bite force recordings and other clinical parameters. (springer.com)
  • The anterior receptors relay information concerning forces in all directions because they have greater sensitivity to occlusal loading. (pocketdentistry.com)
  • Phaner furcifer, and most likely Euoticus elegantulus elicit exudate flow by biting into trees with their anterior dentition. (docme.ru)
  • cranial
  • We conclude that the specific morphology of the palaeognathous upper bill and PPC are not designed for active cranial kinesis, but are adapted to resist external forces that might cause unwanted elevation of the upper bill during feeding. (biologists.org)
  • occlusal
  • Secondly, the possible negative modulation initiation of jaw occlusal muscle movement and hence biting forces stimulated by sensory receptors activation inside the periodontium, and the probable deterrence of a major +ive modulation of jaw occlusal muscle movement and therefore chewing forces also activated by such receptors [12, 13, (medicaljb.com)
  • The mechanoreceptors are very sensitive to low forces and allow for the recognition of occlusal force and the discrimination of load magnitude and direction. (pocketdentistry.com)
  • anatomical
  • This method is further limited in that it cannot shed light on stress-strain distributions, and is therefore ill suited to evaluating the ability of anatomical structures to sustain predicted forces. (royalsocietypublishing.org)

  • However
  • However, rather than alert to the presence of marijuana, the dog instead violently bit an 11-year-old boy on the leg. (dogexpert.com)
  • However, endosseous implants lack the periodontal proprioception feedback system, resulting in less fine motor control and alteration of the awareness of force. (pocketdentistry.com)
  • functional
  • The shorter skulls and mandibles of sea otters, along with increased mechanical advantages of the masseter and increased bite force, form a repertoire of functional traits for durophagy. (biologists.org)
  • comparison
  • They weren't really based or grounded in the modern world by comparison with some living animals for which we knew the bite force. (wuwm.com)
  • excessive
  • Consider the patient who has a chronic popcorn habit - even though their bite force alone might not be perceived as excessive, when you combine this with their habit of continually crunching on any hard un-popped kernels, it might be sufficient to cause untold damage. (mimetikoss.com)
  • Again, they mightn't have an overly-excessive bite force, but add this to their likening for hard fingernails and it may be sufficient enough to eventually cause an implant to fail. (mimetikoss.com)
  • In another lawsuit, the city of Pittsburgh (CA.) settled a case for $145,000 because of the plaintiff's claim that excessive force was used by a police K-9 in his apprehension. (dogexpert.com)
