Definitions

  • the present invention relates to a safety drill assembly for maxillary sinus elevation. More specifically, the perforation of periosteal periosteal elevation to prevent damage to the periosteum of the maxillary sinus during perforation of the implant medium or periosteal elevation of the maxillary sinus It relates to a drill assembly.
  • Implant (dental implant) implantation has been a method of implantation in the alveolar bone of the jaw bone to replace the root, and to connect the crown support to complete the crown has become a fairly common treatment procedure in dentistry.
  • Prosthetic dental implants that have been repaired by implantation should be of sufficient thickness and length to maintain long-term stability.
  • patients with insufficient bone mass should undergo bone graft and implant implants for alveolar bone augmentation with the patient's consent.
  • the maxillary sinus above the alveolar bone is the maxillary sinus
  • the maxillary sinus is lost after the teeth around, the alveolar bone is often retracted as the size increases.
  • a number of implants with bone graft implanted in the maxillary sinus showed a very high success rate.
  • the maxillary sinus graft implants the periosteum at the bottom of the maxillary sinus and fills the bone graft between the elevated periosteum and the alveolar bone so that the implant can be used to maintain an implant of sufficient length after healing.
  • Intramaxillary bone graft is a buccal approach, that is, without opening the buccal alveolar bone without damaging the maxillary sinus periosteum, using the instrument to elevate the periosteum, and after adjusting the alveolar bone with the bone puncture instrument in the jaw adjustment. There is a way to elevate the periosteum.
  • the tooth adjustment approach is generally applicable when the distance between the maxillary sinus and the tooth adjustment is 4 to 5 mm or more. This procedure drills a size smaller than or equal to the perforation diameter corresponding to the implant to be implanted in the repositioning, and implants the bone graft material through the perforation.
  • the advantage of this procedure is that the operation is simpler than the alveolar buccal opening method and the operation time can be shorter for many surgeons.However, the disadvantage is that it is difficult to perforate the alveolar bone without damaging the periosteum in the maxillary sinus without visual observation. It is difficult, and in many cases, even if there is damage to the periosteum during the perforation, the operator is often unknown.

Abstract

La présente invention concerne un ensemble fraise sécurisé pour effectuer une élévation du périoste dans un sinus maxillaire, pouvant perforer un os alvéolaire sans endommager le périoste pendant l’augmentation de l’os alvéolaire réalisée par l’élévation du périoste dans le sinus maxillaire en chirurgie dentaire. L’ensemble fraise sécurisé de la présente invention comprend un connecteur moteur (110) présentant une extrémité dotée d’une partie tige (111) reliée à une source motrice telle qu’une fraise électrique ; un fourreau rotatif (130) présentant une extrémité pour contenir l’autre extrémité du connecteur moteur (110) et l’autre extrémité à laquelle une barre de coupe principale creuse (120) est couplée par vissage ; une barre de coupe supérieure (140) dont une extrémité est ajustée sur la barre de coupe principale (120) et se logeant dans le fourreau rotatif (130) et l’autre extrémité est dotée d’une lame de coupe (141) ; et un moyen de commande (150) placé dans le fourreau rotatif (130) pour commander la connexion entre le connecteur conducteur (110) et la barre de coupe supérieure (140). La présente invention est avantageuse, car la barre de coupe principale présente une partie lame avec un diamètre externe plus grand que celui de la lame de coupe de la barre de coupe supérieure de sorte que le périoste dans le sinus maxillaire ne soit pas endommagé lorsqu’une partie de la fraise passe totalement à travers l’os alvéolaire formé au-dessous du sinus maxillaire. La transmission de la force de rotation entre la barre de coupe principale et la partie tige (111) est déconnectée par le moyen de commande lorsque la barre de coupe (120) a traversé l’os alvéolaire, empêchant ainsi l’endommagement du périoste dans le sinus maxillaire pendant la perforation d’orifices basiques pour poser un implant ou pour l’élévation du périoste.
