Definitions

  • This invention concerns of a wrench which allows tightening of dental implant screws with the intended torque for all dental implant systems as well as unscrewing several screws.
  • This Universal Torque Wrench for Dental Implant Systems consists of a haemostatic like tweezers, in witch the extremities are in the shape of a circle segment, with their inner surfaces corrugated (number 1 in the picture) .
  • This wrench is composed of two arms, divided in a handle, a body and an extremity (numbers 3 and 5 in the pictures) .
  • One of the arms is rigid in his body and possesses a circular (or similar) ending (number 3 in the picture) .
  • To this arm is mounted a dynamometer (number 2 in the picture) which in this case consists of a steel rod. Near the handle of this arm is positioned the scale for the dynamometer (number 4 in the picture) .
  • the other arm is semi-rigid in is body (number 5 in the picture) , meaning it has some flexibility, also ending in a circular (or similar) handle.
  • Both arms are united by a hinge, located in the body, near the semi-circular extremity. Both arms possess a lock (number 7 in the picture) with several possible positions, witch is located in the body, near the handle.
  • the functioning is as follows: when there is a screw to be tightened to a predetermined torque, one grabs the screw connection ( screw driver particular to each dental implant system) and locks it to the Universal Torque Wrench for Dental Implant Systems; next, the driver is delivered to the screw and with a finger leaning on the dynamometer, one tightens the screw by rotating the wrench, until the scale shows the intended torque; finally, one unlocks and removes the Universal Torque Wrench for Dental Implant Systems.

Abstract

De nos jours, des progrès technologiques sont réalisés chaque jour ; de la même façon, des opportunités de développement s'ouvrent dans de nouveaux domaines d’étude, ceci dans une mesure jamais observée auparavant. L’implantologie dentaire correspond à l’un de ces domaines. Aujourd’hui, il existe plusieurs systèmes d’implants dentaires distincts, résultant des grands développements réalisés et d'une demande en croissance constante de la part des patients. Chaque système comprend des pièces et des composants qui lui sont spécifiques et, par conséquent, qui fonctionnent uniquement dans ce système particulier. Pour un praticien dentaire travaillant avec deux ou plusieurs systèmes différents, il devient nécessaire de disposer de différents ensembles de clés ou d'autres instruments pour chaque système, car la plupart du temps les clés sont incompatibles avec tout système autre que le leur. La présente invention comprend une Clé Dynamométrique Universelle pour Systèmes d’Implants Dentaires permettant le serrage et le desserrage des vis d’ancrage ou des vis prosthétiques de tout système d’implants dentaires. Par ailleurs, en plus d’être un outil pratique, cette clé assure le couple de serrage nécessaire et recommandé pour tout système.
