Then the tube is fixed in this position with screws. After fixing the tube, the arrow and the scale plate are removed and in the x-ray model at the desired angle, a through hole is drilled on the occlusal surface with a drill, directing the drill through the tube, which allows the channel to be drilled at the desired angle. Then in the specified through-hole fix the guide sleeve.

Abstract

L'invention se rapporte au domaine de la médecine et concerne notamment des dispositifs orthodontiques de stomatologie pour l'implantation de dents. L'invention concerne un dispositif pour effectuer une implantation transgingivale, notamment pour préparer un gabarit chirurgical 3D, lequel consiste en une structure comprenant des plaques orale et vestibulaire, une base de support ayant une section transversale en forme de coin avec un sommet orienté vers le bas et une échelle de mesure sur les surfaces avant et arrière et qui comprend vers le haut une ouverture en forme de fente au centre de laquelle est disposé verticalement un tube pouvant s'incliner par rapport à son axe vertical; le tube vient se fixer à des supports disposés à l'avant et à l'arrière de la base et définissant des protubérances au-dessus de sa surface; sur la surface d'extrémité du support arrière du tube se trouvent deux petits renfoncements disposés en diagonale l'un par rapport à l'autre et servant à placer les plaques à une distance voulue depuis le centre à l'aide d'un pied à coulisse électronique; la fixation du tube dans le support se fait à l'aide de vis dans la partie inférieure des supports, et la fixation du tube selon un angle donné est réalisé à l'aide de vis latérales orientées des deux côtés vers l'intérieur vers le centre de la base et disposées dans la partie inférieure de la base; dans la partie supérieure de la surface arrière de la base se trouve une bande ondulée pour la fixation à l'aide de vis de plaques, et un évidement rond sur le côté gauche sous la bande ondulée en vue de la fixation à l'aide d'une vis d'un rapporteur dans une position donnée. Le résultat technique consiste en un fonctionnement plus efficace et plus précis du dispositif, permettant de créer fonctionnellement un gabarit chirurgical 3D ultra-précis en la présence du patient, et excluant toute nécessité de correction sur la mâchoire du patient, ce qui réduit le temps de réalisation de l'opération et améliore sa qualité.
