Definitions

  • Device for planning and drilling implant bearings in the human jaw.
  • the invention presented here is used in oral implantology for planning implant positioning and for performing jaw bone drilling for receiving implants.
  • implants are inserted into drilled shafts of the jawbone and are impacted by the surrounding jawbone after an individual healing time and can be used as anchoring for dentures.
  • Model and X-ray analyzes are necessary to determine the most favorable implant positions.
  • an impression is taken from the jaw to be supplied with a suitable, dental impression tray, which is filled with a suitable impression material (usually silicone), which is then poured out and cured with pouring material (usually plaster), which creates a model that is created resembles the molded jaw in shape and size.
  • a suitable impression material usually silicone
  • pouring material usually plaster
  • dental film for X-ray analysis, dental film, orthopantomography and computer tomography X-rays are used, with which the internal jaw structures can be displayed.
  • the invention presented here combines all measures in a coherent, error-minimizing and result-optimizing manner.
  • the base spoon 15 belonging to the invention is used for model generation and supplemented with further devices belonging to the invention, also used for X-ray analysis.
  • the implant positions determined by the model and X-ray analysis can be transferred to the natural jaw in a precise location and the bone holes can be carried out in a manner identical to the plan, thereby achieving a good prognosis for the success of the implants. Incorrect drilling, which can lead to trauma, healing delays or implant rejection, is avoided.
  • the implant retention period is extended by the precise planning implementation, which reduces health risks and costs and increases the quality of life of the implant wearer. The duration of the operation is shortened and stress factors for the patient and the practitioner are reduced.
  • the implementation of implant care is made easier and accessible to other users, which means that a broader section of the population can participate in this therapy.
  • the invention consists of a base tray 15 which is similar in shape and application to the impression trays used in dentistry. It is composed of a base frame 16, several different segments 50 and a back rail 43.
