Abstract
Currently dental laboratories use a lathe for the polishing of the dental crown. Such lathes use a polishing disc brush mounted on a rotating shaft and which generally cannot polish the deeper parts of the surface of the appliance without wearing down the surrounding anatomy. The present device provides a brush which uses an orbital motion to thereby better preserve the anatomy of the crown.
Description
The cross reference of relevant application
The application be propose August 1 calendar year 2001, part continuation application that application number is 09/920,046 U.S. Patent application.
Technical field
The present invention relates to polish the dental appliance or the jewellry of corona, bridge, artificial tooth and analog, more specifically say, the present invention relates to orbital polishing corona, bridge, artificial tooth and the dental appliance of analog or the device of jewellry.
Background technology
Present dental laboratory can prepare corona, bridge and the such dental appliance of for example artificial tooth.When corona is come out by billon or ceramic casting, need the upper surface of polishing corona.Resembling the corona upper face of nature tooth or function surface has complicated convoluted shape or comprises protruding ridge, groove and the structure of dark concavity.It is very important that the dark structure and the combination of protruding ridge can have appropriate functional for tooth, and produce pressure still less on root of the tooth.
Present dental laboratory uses lathe polishing corona or dental appliance.This lathe uses the scaife brush of being made by hard brush that is installed on the dwang.The EDGE CONTACT crown surfaces of rolling disc.Because for dish, the radius size of dish is too big,, therefore can not under the situation of the surrounding structure that do not wear and tear, polish the depression depths usually to such an extent as to can not enter depression.Similarly, can not arrive all parts of groove and ridge at the situation lower wall of the corona structure of not wearing and tearing, this is that people are undesirable.Therefore need to protect the device that is used to polish corona, bridge or dental appliance of corona structure.
Brief summary of the invention
The device that is used to polish the workpiece with convoluted surface provided by the invention comprises: brush support; Make brush support produce the electric motor of orbital motion; And being installed in polishing brush on the brush support, it comprises crooked working surface.According to an aspect of of the present present invention, brush has hemisphere surface.Hemisphere surface is preferably towards vertically downward direction.Device can have horizontal base, also can comprise vertical motor supporter.Motor can be installed in the electric machine casing that is positioned on the described vertical motor supporter.Preferred brush supporting disk extends downwards from described electric machine casing, and device preferably has a plurality of brushes that are installed on the described brush supporting disk.
Brief description of drawings
In illustrating the accompanying drawing of the preferred embodiment of the present invention:
Fig. 1 is the perspective view of crown surfaces;
Fig. 2 is the perspective view according to polishing device of the present invention;
Fig. 3 is a side view of the present invention;
Fig. 4 is a details of conveniently removing the polishing brush of the present invention of brush guard shield for diagram;
Fig. 5 removes the diagrammatic sketch of electric machine casing with motor that track operation is shown better;
Fig. 6 is the perspective view that brush amplifies; And
Fig. 7 is the partial cross section figure of brush shown in Figure 6.
The specific embodiment
In the following description, for to the invention provides more thorough understanding, detailed clear and definite details has been described.Yet the present invention also can realize under the situation that these details are not described.In other example,, do not illustrate or describe in detail known elements for avoiding causing unnecessary obscure of the present invention.Therefore, specification and accompanying drawing should be regarded as exemplary example, rather than restrictive example.
With reference to Fig. 1, the corona 10 that is made of precious metal, pottery or acrylic resin resemble the billon is shown, it has upper face or the function surface 12 that circles round, and above-mentioned surface has marginal ridge 14, cheek side point (buccal cusp) 16, tongue side point (lingal cusp) 18, triangular ridge 20, groove 22 and caves in 24.These complex characteristic of function surface are called structure.
Fig. 2 to 5 shows polishing device 30 of the present invention.It has pedestal 32, power supply 34, switch 36, vertically bar 38 and machine case 40.Brush guard shield 42 is connected on the machine case 40.What extend downwards from brush guard shield 42 is at least one brush, and preferred three or more brush 44,46,48.Brush 44,46,48 are formed by those polishing brush silks that are used to form existing lathe polishing brush.Has different shapes according to each brush of the different task of wanting to realize.Preferred brush has curved surface, normally has different radii to allow the hemisphere surface of polishing different surfaces.The a plurality of brushes that provide also allow to use the buffing compound of the different roughness from coarse to meticulous on each brush.Buffing compound is poured in the opening 68 of each container 60 that is supported by supporter 64, arrives brush by pipe 62 then, and described pipe 62 is connected each container 60 by the hole 70 (Fig. 6 and Fig. 7) on each brush with brush.
Brush 44,46,48 is installed in (Fig. 5) on the brush board 50, and described brush board 50 extends downwards and is fixed on the dish 52 from the dish 52 along the motor 54 of track operation.Brush board 50 extends enough degree of depth downwards, makes the technician in the other work of device can see surface of the work.Suitable motor 54 can adopt the motor in the Makita polishing processing machine (Finishing Sander) that motor in the sanding machine (Random Orbit Sander) along a certain random track operation or model be BO4552K.A point on the polished surface in this sanding machine randomly around fixed center o'clock in a plane along track operation.Therefore the lip-deep point of sanding machine (for example brush in the present embodiment) carries out continuous random motion in a closed path, for example centers on circle or oval path that the central point rotation in the plane forms.This planet that resembles is distinguishing with resembling planet around the spinning motion of the axle rotation of self around the orbital motion of solar motion.Switch 36 starting and disable motors, and do not produce velocity variations.Also can use motor, although do not need pace of change usually with variable velocity.
In when operation, the technician of burnish gold corona to start motor 54 along a certain track operation, it makes brush 44,46,48 produce orbital motion fast, just as along in the sanding machine of a certain track operation.The technician selects to have the brush of suitable radius and/or buffing compound then, and the contact crown surfaces, polishes it then.Owing to do not resemble existing polishing device, the corona structure of therefore not wearing and tearing.
Although being described, the present invention is used to polish corona, bridge and the such dental appliance of for example artificial tooth, but the present invention can be used for polishing any nonplanar surface, especially have complexity or the crooked nonplanar surface of circling round, comprise jewellry, little punch die fabrication portion and computer chip.
Those skilled in the art according to the disclosed content in front obviously as can be known, it is possible in actual use the present invention being carried out many change and modifications that do not deviate from spirit and scope of the invention.Therefore, protection scope of the present invention is limited by the content of following claim.
