WO91/02496 'i'''2 0 6 ~ 7 9 o PCT/SE90/005 f- Method of manufactoring restorations, prosthesis or the like within dental and medical service 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.
According to common technique within dentistry when repairing the teeth the dentist after having drilled the tooth that shall be filled makes an impression of the tooth. There-after a model of the tooth is made in plaster, which is uti-lized by a dental technician as a model when waxing and mould-ing the restoration. This method is very troublesome and time-consuming and creates many sources of errors. Therefore, new methods of producing restorations and dentures within dentistry have lately began to be developed.
According to a method described in European Patent No. 0 054 785 there is previously known to make an optical reading of the form of the cavity of the tooth. This information is trans-mitted to a computer, a manual completion of the information being made. The computer controls a milling-machine which shapes a material, whereby a restoration is produced with a form which is similar to the form of the cavity. According to another method which is described in the US patent No.~4~182 312 there is previously known to convëy a probe around in the 'cavity of the tooth, the form of the cavity being detëcted. The '''' information from the probe is transmitted to a shaping machine in a mechanical way, which prepares a restoration with a form "which'is similar'to that of the càvity. None of these two ,u methods, however, gives a satisfactory result but additional working is required.

points and being an integral part of a measuring device pr~- -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 ànd/or receivérs. The - ~cameras'are'intended to cooperate with a mëasuring probe 3 having a point 4. This point is intended to be conveyëd along the;surface''of the 'cavity for instànce. The ~measuring probe 3 further comprise's'three'iighting points 5-i, which can be activé in~thè form of light'èmitting diodès or passive in the -~' form of reflectors. Thé'charàctèrizing thing for the light ~ -'emitting~diodès i's that they'suitably'émit,IR-light while the reflectors'reflëct IR-iight. The point 4 of the measùring probe 3 has known'coordinates (x,y,z) in rèlation to the three light-. . , ~

`-` ing points. Due to that fact the coordinates in the space of the three lighting points can be registered by means of the two cameras which have stationary positions. of course, 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.
When the point 4 of the measuring probe 3 is accordingly con-veyed along for instance the surface of the cavity, 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.
In order to determine the form of the cavity of the jaw for instance in a more secure way when the patient moves his head it is suitable to arrange three lighting points 8-10 as reference points in the upper jaw or the lower jaw of the patient. If instead three cameras are utilized, it is suffi-cient to have two lighting points as reference points in the upper jaw or the lower jaw.
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. Thus, with this method it is possible to achieve a very great accuracy when making treat-ments within dentistry and medical service.
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. Of course, 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 W O 91J02496 ~i ~`5 47 9 '3 4 PC~r/SE90/00534 of the new method within the medical service is the produc ~ n of artificial limbs for mutilated arms and/or legs.
