Definitions

  • the present invention relates to a device, system and method for producing a dental implant drill guide and in particular to such a device system and method for positioning a drill guide sleeve within a drill guide to determine the drill path for positioning a dental implant at an implantation site over an edentulous site.
  • Dental implants are well known in the art and typically include a dental anchor securely inserted into the patient's jawbone, and an abutment member mountable to the dental anchor, the abutment utilized for coupling a restoration .
  • One of the initial steps in the implantation process and perhaps the most crucial step is determining where to place the implant anchor within the jawbone over the edentulous area.
  • This first initial step is crucial in that it determines the quality of the implantation process and the likelihood of its success. Therefore the initial determination of where to drill, at what angle, depth and size, greatly impacts the success of the implantation process. It is extremely important that the hole drilled in the bone tissue has a correct location and inclination with respect to the thickness and morphology of the bone. Care is to be taken to avoid any imperfect fit of the implant, and, most critically, to avoid any perforation or damage to nearby anatomical structures .
  • the planned procedure generally includes determining the drill sequence, drill location, size and depth.
  • a drill guide has been developed that provides a practitioner with the tool to minimize errors .
  • a dental drill guide is an acrylic resin mask obtained from a model of the patient's dental arch, adapted to exactly fit over the patient's teeth and/or edentulous areas of the jaw (or just "over the patient's jaw").
  • the guide mask is provided with one or more guiding holes that are placed in the exact position of the holes to be made or, more preferably, it is provided with one or more metallic hollow cylinders plunged in the resin in the desired locations .
