Definitions

  • the subject invention generally pertains to dental implants and more specifically to a tool for installing them.
  • the subject invention pertains to a method for adjusting the position of a drill bushing used for installing the implant.
  • a final product comprises three basic components: an implant, an abutment, and a crown.
  • the crown is the exposed portion of the prosthesis that resembles one or more teeth.
  • the implant is an anchor that becomes attached to the jawbone, and the abutment couples the crown to the implant.
  • a hole is usually drilled into the patient's jawbone, and the implant is inserted into the hole.
  • a drill bushing attached to a stent can be used to help guide the drill bit, as disclosed in PCT Publication WO 99/26540 and U. S. Patents 5,015,183; 5,133,660; 5,718,579.
  • a drill bushing can be difficult to attach to a stent, particularly if the drill bushing is to be pivotal relative to the stent as is the case in the 5,718,579 patent.
  • Typical implant methods involve a series of procedures extending over several months.
  • the process involves first, cutting the gum tissue in the area of the missing tooth and pulling the tissue back to expose the jawbone; second, drilling a hole into the bone; third, installing an anchoring member or implant into the hole; fourth, attaching a cover screw to the implant and stitching the gum tissue back together; fifth, waiting up to several months to allow the gum tissue to heal over the cover screw and to allow the bone to grow onto the implant; sixth, cutting a small round hole in the gum tissue to remove the cover screw and expose the implant; seventh, attaching a healing cap to the implant; waiting another extended period to allow the gum tissue to heal around the healing cap; eighth, replacing the healing cap with an abutment; and ninth, attaching a crown (e.g., an individual prosthetic tooth, bridge, denture, etc.) to the abutment.
  • a crown e.g., an individual prosthetic tooth, bridge, denture, etc.
  • the Klein method involves taking a CT scan (computed tomography scan) of a patient wearing a surgical template that overlays the patient's teeth.
  • the surgical template preferably has three fiducial markers that are detected by the CT scan.
  • the surgical template is removed from the patient's mouth and placed over a model of the patient's jaw.
  • the model jaw with the surgical template is loaded onto a computer- driven milling machine. With the aid of the CT scan data and the three fiducial markers, the milling machine accurately drills a hole into the surgical template.
  • the template now with an accurately drilled hole, is returned to the patient's mouth, so the hole in the template can then be used as a drill guide when drilling into the patient's actual jawbone.
  • Drawbacks of such a method include its overall complexity and the expense of the computer-driven milling machine.
  • Another implant method and related device is disclosed by Fenick in U. S.
  • Fenick uses X-rays to help identify a drill bit trajectory and uses drill guide bushings to help guide the drill bit.
  • the Fenick system creates a radiology stent that includes a radially opaque grid.
  • the stent without any drill bushings, is X-rayed while in the patient's mouth.
  • the stent is then placed over a model of the patient's jaw where the grid provides a frame of reference that helps in manually positioning a drill bit relative to the model jaw.
  • a hole is drilled into the model, and the resulting hole helps align a drill bushing relative to the model.
  • a cast is created over the model to capture the drill bushing.
  • the cast, with the drill bushing, is then placed in the patient's mouth to help guide the drill bit that drills a hole into the patient's jawbone.
  • some positional accuracy may he sacrificed because the drill bushing is aligned to a model rather than being aligned directly to the patient's actual jaw.
  • Kennedy is of particular interest.
  • Kennedy discloses a method of adjusting the angular position of a drill bushing that is press-fitted into a hole in a splint.
  • a tool helps in prying the bushing to a proper orientation.
  • the Kennedy system has a few drawbacks.
  • the pivotal point of the bushing is adjacent to the surface of the gum tissue, so as one end of the drill bushing is aimed toward the jawbone, the opposite end may point away from the desired center point of the prosthetic tooth.
  • an angled implant/abutment e.g., Figure 26B of U. S. Patent 6,283,753
  • Such an angled implant/abutment may have been avoided if a proper drill trajectory had been established in the first place.
  • a second problem with the Kennedy system pertains to the drill bushing being press-fitted into a simple hole in a splint.
  • a cylinder such as a drill bushing
  • the bushing and hole will naturally urge themselves into coaxial alignment with each other.
  • the bushing can be forced out of alignment to some extent, but the degree of angular adjustment is significantly limited.

Abstract

L'invention concerne un outil dentaire permettant de guider un foret ou un emporte-pièce pour biopsie pendant une procédure d'implantation d'un implant dentaire. Cet outil dentaire comprend une bague de foret montée pivotante sur un support. Ce support de bague est lui-même monté sur un stent chirurgical qui se loge dans les dents, les gencives et/ou la maxillaire d'un patient. Le montage pivotant entre la bague de foret et le support de bague permet de régler l'orientation angulaire de la bague de foret, de façon que la trajectoire du foret ou de l'emporte-pièce pour biopsie puisse être dirigée directement sur la mâchoire du patient. Une fois la bague de foret dûment orientée, la bague est liée au support de bague afin d'empêcher tout mouvement entre la bague et le support.
