Artificial dental articulators are used to arrange artificial teeth at their own positions and reproduce mandibular movements in accordance with Temper Mandibular Joint Movement. It can be called a mechanical jaw.
  • articulators come in many different forms, ranging from very simple retractable instruments to very complex and sophisticated instruments, and are generally classified according to their degree of adjustment.
  • Non Adjustable Articular, Semi-Adjustable Articulator, Complete It is divided into adjustable articulator.

Abstract

L'articulateur dentaire de la présente invention comprend : une paire de moyens de selle supérieur et inférieur qui sont raccordés de manière amovible aux axes centraux des socles de support réglables horizontalement situés au centre des plaques supérieure et inférieure et qui sont réglés pour se déplacer horizontalement vers l'avant, vers l'arrière, vers la gauche et vers la droite ; et une paire de moyens de support de plateaux supérieur et inférieur qui sont raccordés de manière amovible aux surfaces intérieures de la paire de moyens de selle supérieur et inférieur, respectivement par des forces magnétiques, et qui supportent des plateaux supérieur et inférieur, dont la relation intermaxillaire est ajustée dans la cavité buccale du patient, par ajustement par pression de telle sorte que les plateaux supérieur et inférieur se font face. En conséquence, il est possible de reproduire avec précision la relation intermaxillaire (intervalle entre les mâchoires) d'un patient particulier dans l'articulateur par une opération simple. De plus, les plateaux supérieur et inférieur utilisés pour la fabrication de prothèses dentaires, dont les moulages (empreintes) sont effectués sur le patient, peuvent être simplement fixés au niveau de positions prédéterminées par des forces magnétiques, ce qui permet de procéder rapidement et avec précision aux réglages, dans le plan horizontal et vertical, de la relation intermaxillaire.
