Definitions
- This invention relates to the coating of a ceramic on a dental substrate by electrophoresis in an aqueous slip.
- a substrate according to the invention is understood to mean any article in dental technology on which a ceramic material is applied.
- aqueous slips of dental technology are used to produce fully ceramic substructures, especially alumina caps.
- the stump of a working model is coated with a separating agent, on which a silver coating according to the practical example is applied.
- the solids of the slip are electrophoretically precipitated on the silver coating by application of a voltage.
- a common feature of both instructions is the disadvantageous use of silver lacquer, since experience has shown that an imprecise fit results, in addition to the increased time and material demands.
- vapors that are hazardous to health and non-biocompatible residues are also formed, which must be removed from the sintered ceramic in time-consuming fashion.
- the silver lacquer also has a tendency toward uncontrolled bubble formation.
- the use of a silver lacquer is fully unsuitable if the ceramic material applied by electrophoresis is to remain on the substrate, as is the case during application of a dentin or cutting mass, since in addition to mechanical weakening, unacceptable visual properties result.
- the task of the invention stated in claim 1 is therefore to provide a method that permits electrophoretic coating of dental substrates with the highest precision in the shortest time.
- the invention is a method for coating dental substrates with a ceramic by electrophoresis in an aqueous slip and is especially for coating a stump of a working model or an implant abutment with alumina or zirconia.
- the substrate is fixed in a vertically moving holder in an insulating mass and is coated with a separation agent.
- a hygroscopic salt layer is applied onto the separation agent.
- the coated region is dipped into the slip and then the substrate is pulled out from the slip far enough so that, during subsequent application of a voltage, only the part of the substrate to be coated with the ceramic is situated in the slip.
- FIG. 1 shows the production of a cap
- FIG. 2 shows coating of an implant abutment.
- a vertically movable holder 1 is shown in FIG. 1 , on which the stump 2 of a working model is fastened by means of an insulating mass.
- the holder is connected to the plus pole (not shown) of a power supply and consists of an electrically conducting material.
- the insulating mass 3 is bridged by a tongue 4 so that the stump 2 can have electrical contact with the plus pole.
- a separation layer is initially applied to stump 2 , as is known for example from DE 198 12 664 A1, which can advantageously be coated with the solids of slip 6 , for example, with alumina if the cap being produced is supposed to consist of alumina.
- a concentrated NaCl solution is then applied to the coated region, which can contain commercial detergents.
- the coated region is shaded in FIG. 1 and extends to plane O-O.
- the stump 2 is then briefly dipped into the container 5 filled with slip 6 up to plane O-O and withdrawn in the depicted position. Only the part of the stump 2 to be coated is still situated in slip 6 .
- the stump 2 therefore has a total layer that, viewed from the inside out, consists of a separation layer, optionally a ceramic powder layer, a hygroscopic salt layer and a slip layer.
- the stump 2 After application of a voltage to about 40 V, the stump 2 is connected to the plus pole via tongue 4 , whereas the minus pole is formed by the container 5 .
- the conducting salt layer on the non-conducting stump 2 made of gypsum causes a precipitate 8 on the stump.
- This precipitate 8 is then dried in known fashion, machined by a CNC milling machine, sintered and glass-infiltrated and finished to a cap.
- Coating of an implant abutment 12 made of titanium is shown in FIG. 2 and occurs in similar fashion to the coating of a working stump just described.
- the implant abutment 12 is fastened in a holder 11 by means of an insulating mass 13 , for example, conventional molding compound made of a thermoplastic.
- the implant abutment is shown in the electrophoresis position after it has been dipped into the slip 16 in container 15 up to plane O′-O′.
- the layer 17 also covers the lower region of holder 11 up to plane O′-O′.
- This layer as in the first example according to FIG. 1 , consists of a separation layer, optionally the ceramic powder, an overlying hygroscopic salt layer, which is covered by the slip.
- precipitate 18 is formed, which is further processed in known fashion.
- the teachings are not restricted to the production of caps (for example, from alumina) or to coating of implant abutments with dentin mass, since any conceivable dental substrate can be coated with the method according to the invention.
- Metal substructures can thus also be coated with dentin mass.
- the application of a cutting mass on dentin is also possible.
