Definitions
- the invention relates to an automatic machine tool for producing basic frameworks for dentures, in particular for tooth crowns and / or dental bridges, of a precise three-dimensional shape, which basic frameworks can be attached to prepared natural and / or artificial tooth stumps, the machine tool being a machine frame or housing , a workpiece carrier with a rotating shaft, at least one digitizing unit, at least one processing unit and an electronic computing and control unit for all drive elements. Furthermore, the invention relates to a method for producing positive frameworks for dentures with the automatic machine tool
- a number of devices and methods for the production of artificial dental bridges and dental crowns are known, which are referred to collectively as dental prostheses. Basically, after the dental preparation, an impression of the tooth stump, the dental environment and the jaw is made. Furthermore, a system with an oral camera is known, which derives the processing data from the images taken in the mouth without going over the print
- a so-called master model can be made from the impression using a plaster cast.
- This master model shows the situation in the patient's mouth from plaster.
- the dental technician uses this master model to craft a model of the basic structure of the denture in wax as well as melting or polymerizing at a low temperature Plastic
- This model can be used in refractory beds, baked out and then cast from metallic materials.
- the wax model, this name is also used when plastic is used, but can also be transferred to another material by mechanical copy processing on a scale of 1 1, enlarged or reduced.
- a basic framework made of ceramic material for tooth crowns and / or bridges is densely sintered and shrinks to the final shape, in such a way that the basic framework can be placed precisely on the tooth stump later - Bring a coating of porcelain (field gap ceramic) or plastic on the outer surface of the basic structure, if necessary, the tooth crown or dental bridge can be customized
- WO, A1 96/05782 describes a manually operable, analog working device for producing dental fillings and the like.
- the device contains two spindles for rotating a model and a blank. The rotation of the model and blank must be synchronous perpendicular to the axis of rotation of the model and the blank
- a sensor is attached to the model and a processing tool is attached to the blank. If the model and blank rotate, the sensor is manually brought into contact with the model surface. At the same time, the processing tool processes the blank accordingly. If the sensor is moved over the entire model surface, a scale copy of the model is produced.
- This embodiment includes the non-adjustable scaling, ie the lack of enlargement or reduction, the manual operation, the necessary exact coordination of probe and tool, and the problems in the production of bodies with cavities (con kave surface shape)
- the device described in WO, A1 96/05782 is therefore not suitable for the automated production of dental crowns and dental bridges of any geometry
- the digitization of the surfaces of a master model roughly provides the cavitation surface of the basic structure. Cementation gaps and the occlusal surface of the basic structure have to be supplemented when calculating, e.g. via flat or volume-recirculated, elaborate three-dimensional models.
- the working methods and tools therefore do not correspond to the traditional, artistic working methods of a dental technician nevertheless require specially trained specialist staff
- the present invention has for its object to provide an automatic machine tool of the type mentioned and a method for producing positive basic frameworks for dentures, which allow safe manufacture with a small and easy-to-use device a porous Keramikgru ⁇ ng, after sintering high-strength ceramics, but also for basic frameworks made of plastic or another easy-to-work material
- a carrier for the workpiece is a blank and / or for the machining units is designed as a movement unit with three translation axes in the x, y and z directions.
- the workpiece carrier can be moved in the x, y and z directions, that is to say the directions of a rectangular spatial coordinate system, in the case of a stationary processing unit.
- the control is carried out in such a way that a linear displacement of the workpiece carrier, which is preferred, takes place simultaneously and quickly in two or in all three directions.
- the translation axes are designed as linear rails
- the translation axis function in the x-direction can be taken over by the rotation shaft of the workpiece carrier, in that it can be extended or shortened in a torque-proof manner.
- the rotation axis as a whole can also be displaceable in the axial direction
- the mentioned rotation shaft of the workpiece carrier has clamping devices on both ends, on the one hand for a blank to be machined, and on the other hand for a dental preparation model.
- the blank consists, for example, of at least one of the metal oxide powders AL 2 0 3 , TiO 2 , MgO Y 2 0 3 or a zirconium oxide mixing cabinet.
- the dental preparation model is generally a positive model, but can also be a negative model
- the rotary shaft has a clamping device for a blank and a dental preparation model only on one free end face.
- the other end of the rotary shaft is anchored in the movement unit
- the processing and digitizing unit of the machine tool must be quick and easy to replace. This can be done, for example, with a bayonet lock, but means for moving are preferably provided, for example one Linear rail or a swivel device, each with a lock in the working position
- the machine tool can comprise a plurality of processing units, two processing units opposite one another with respect to the rotation shaft are expediently provided, in particular above - below, front - back or left - right, depending on the rotation shaft, as usual, being arranged horizontally or exceptionally vertically
- a processing unit of a machine tool each comprises one or more, preferably several, processing tools. These processing tools are not the same but different for the rough and fine machining, which also affects the dimensioning of the tools. Usually two machining tools are arranged according to geometrical considerations. Examples of machining tools in the narrower sense are grinding pins or milling cutters for machining, or radiating machining tools for machining by laser or Elektroerros.on
- the input of scaling factors is essential. This can be done manually using a keyboard that is connected to the computing and control unit, but is preferably done via a connected reading device for optical electrical, magnetic or mechanical-tactile input
- the object is achieved according to the invention in that the digitization of the preparation model and the processing of the blank are performed on the same machine tool in a time-decoupled manner Processing of the blank from the determined and stored digitization data and a predefined, material-specific scaling factor. The processing paths for the blank are calculated.
- the scaling factor can be exactly 1, but in practice it is usually between 1 and 1, 5, in particular between 1, 2 and 1, 3. ternalb of 1, then the preparation model is reduced accordingly
- a positive dental preparation model is digitized.
- a negative model can also be spanned, the digitized data being converted in such a way that a positively processed blank is produced.
- the cavitation and occlusal digitization and conversion into processing paths of the processing unit is preferably carried out without assembly in the electronic control unit.
- the use of CAD / CAM is therefore - as already mentioned - neither necessary nor sensible. In other words, you do not have to perform a surface return or a return of the digitized surfaces in CAD systems based on the digitized data. Post-processing of the data, for example inserting standardized links from a library via CAD, is therefore unnecessary. Working on such systems would require special knowledge and skills and would be restricted by the use of standardized links in terms of individuality for the patent situation.
- To digitize the entire surface of the preparation model a basic setting is first brought up
- the rotation shaft rotated once by 180 °, or three times by 90 °, or - five times by 60 °.
- the axis can also be rotated through different, identical or unequal angles until the entire surface of the preparation model is digitized.
