Definitions
- This invention relates to a method of producing restora- tions, prostheses or the like within dentistry and medical service, a measuring device, a computer and a shaping machine being utilized.
- This invention relates to a method that shall produce restorations, prostheses or the like., which have better fit than restorations and prostheses produced according to known methods. This has been made possible by the method according to the kind mentioned by way of introduction, which is character ⁇ ized by the combination of the following moments:
- a measuring probe provided with at least two lighting points and being an integral part of a measuring device pro ⁇ vided with at least two cameras is conveyed along the treatment area at the same time as the movements of the measuring probe are registered by means of the cameras;
- Data from the cameras are collected by and stored in a computer which is specially programmed for this field of use and which on basis on incoming data can determine the form of the treatment area;
- the data information stored in the computer is utilized for controlling a shaping machine which out of a working piece shapes a suitable restoration or prosthesis.
- An essential advantage with this new method is that the form of the treatment area can be determined even if this one is not visually available. According to the new method every separate measuring point in the space becomes evidently defined regarding xyz-coordinates. These measuring data are stored in the computer and can then be the base when shaping the working piece in the shaping machine.
- a preferred embodiment of a device for measuring the form of a treatment area inside the mouth of a person for instance shall be described more closely with reference to the accom ⁇ panying drawing.
- This device is very suitable to use for measuring the form of holes for instance in the teeth made by means of drilling. In that connection the device measures and calculates the internal contour of the cavity of the tooth.
- the device comprises two cameras 1, 2, which is suitably of CCD-type. These cameras are intended to register the posi ⁇ tion of light emitting diodes from different directions and accordingly function as transmitters and/or receivers.
- the cameras are intended to cooperate with a measuring probe 3 having a point 4. This point is intended to be conveyed along the surface of the cavity for instance.
- the measuring probe 3 further comprises three lighting points 5-7, which can be active in the form of light emitting diodes or passive in the form of reflectors.
- the characterizing thing for the light emitting diodes is that they suitably emit IR-light while the reflectors reflect IR-light.
- the point 4 of the measuring probe 3 has known coordinates (x,y,z) in relation to the three light- ing points.
- the coordinates in the space of the three lighting points can be registered by means of the two cameras which have stationary positions.
- the number of cameras can be more than two but if the number of lighting points of the measuring probe is three, it is sufficient with two cameras. If instead three cameras are utilized, it is sufficient to have two lighting points on the measuring probe.
- This described measuring device is connected to a com ⁇ puter, whereby data from the cameras can be fed into the computer which is programmed for this special field of use.
- the coordi ⁇ nates in the space of the three lighting points can be exactly determined for different positions, the surface and the form of the cavity being able to be determined by means of the com ⁇ puter.
- Data about the form of the measured cavity which have been collected by and stored in the computer can now be used for controlling a shaping machine, for instance a milling- machine, which out of a working piece shall produce a restorat ⁇ ion or the like with the same form of that of the cavity, which restoration is fastened into the cavity of the drilled tooth by the dentist in a suitable way.
- a shaping machine for instance a milling- machine
- which out of a working piece shall produce a restorat ⁇ ion or the like with the same form of that of the cavity, which restoration is fastened into the cavity of the drilled tooth by the dentist in a suitable way.
- a treatment area When describing the device the cavity of a tooth in which there has been made a hole by means of drilling has been mentioned as a treatment area.
- other treatment areas may be possible, for instance the upper jaw and/or the lower jaw when inserting dentures.
- An example of a utilization area of the new method within the medical service is the production of artificial limbs for mutilated arms and/or legs.
