Definitions

  • the present invention relates to a drill for implant surgery, and more particularly, to a drill for implant surgery capable of guiding the angle of drilling.
  • Implant surgery refers to a procedure in which an implant is implanted in place of a damaged natural tooth.
  • a drill is drilled into the alveolar bone and then a fixture is placed. Then, after attaching the abutment to the fixture, the final prosthesis is mounted on the abutment.
  • a drill for implant surgery is used to perforate the alveolar bone to place the fixture.
  • the drilling angle of the drilling does not match, the implanted fixture is misaligned with the surrounding teeth. Therefore, the drilling angle of the drilling is important. So, to check the angle of drilling before drilling, first form a groove, insert a pin into the groove, and then check the drilling angle. If the drilling angle is correct, remove the pin and drill at that angle.

Abstract

La présente invention concerne un foret de chirurgie d'implant et, plus spécifiquement, un foret de chirurgie d'implant apte à guider un angle de forage. Le foret de chirurgie d'implant selon la présente invention comprend une broche de guidage, un moyen de forage et un moyen de pression. La broche de guidage peut être insérée dans une rainure formée dans l'os alvéolaire de telle sorte qu'une broche pour confirmer l'angle de forage peut être insérée à l'intérieur de celle-ci. Le moyen de forage présente une extrémité qui peut être montée au niveau d'un outil rotatif, et une partie de réception recevant la broche de guidage pour amener la broche de guidage à saillir de l'autre extrémité de celle-ci et à être insérée dans la rainure et coulisser dans la direction axiale de la broche de guidage, et ainsi l'os alvéolaire peut être foré. Le moyen de pression est monté dans le logement pour presser la broche de guidage de telle sorte que la broche de guidage saille du moyen de forage. Selon la présente invention, la broche de guidage est insérée dans la rainure de l'os alvéolaire pour guider un angle de forage. Par conséquent, le foret de chirurgie d'implant de la présente invention coulisse le long de la broche de guidage pour permettre le forage, et peut ainsi forer à l'angle de forage sans dispositif de guidage séparé.
