Description

[Detailed description of the invention] The present invention relates to a processing device for dental restorative parts, and more specifically, improves the aesthetic appearance of dental restorative parts, such as dentures and dentures, made of dental resin compositions and dental composite resin compositions. The present invention relates to a dental restorative component processing device for significantly improving the surface hardness and wear resistance of the dental restorative component.

Here, the dental composite resin composition refers to a dental resin composition containing an inorganic filler.

Restorative parts made of resin or composite resin compositions, such as dentures and table tops, have advantages over restorative parts made of ceramic or metal, such as being easier to manufacture and being relatively low-mounted. has been attracting attention and being adopted.

However, dentures made of restorative materials made of resin or composite resin compositions, such as polymethyl methacrylate or polycarbonate, have inferior surface gloss compared to natural teeth.
In particular, during use, it is easily worn out by friction and contact with food and natural teeth, or abrasion with a toothbrush or toothpick.
It has been pointed out that the problem is that the denture wears down, its surface gloss decreases, and the denture becomes rough, degrading its aesthetic appearance and further making the denture uncomfortable to wear.

As a means to improve such drawbacks, a method has been proposed in which a coating liquid containing a polyfunctional acrylate as a main component is applied to the surface of a restorative member such as a denture or a denture, and then cured and processed.

However, a dedicated device for processing and producing a restorative member by implementing such a method has not yet been developed, and it has not been possible to easily apply this method in dental clinics and the like.

When such processing is necessary, it has to be requested at an appropriate location, which has the disadvantage of requiring a lot of treatment time.

The present invention was developed in view of this situation, and its gist is to provide a dental restoration in which an active energy ray-curable coating liquid is applied to the tip of a box body 1 equipped with an opening/closing door 11 on the front. A plurality of supporting bodies 3 supporting the member 2 and rotatable around the axis thereof, and an active energy ray irradiator 4 that irradiates the dental restorative member 2 from above the supporting bodies 3 are disposed, A dental restorative member processing apparatus is provided so that a large number of restorative members can be processed simultaneously.

To explain in detail with reference to the drawings which are embodiments of the present invention, the dental restorative component processing apparatus according to the present invention is shown in FIGS. 1 and 2.
As shown in the figure, inside a box 1 having a simplified opening/closing door 11, a dental restorative component 2 whose tip is coated with an active energy ray-curable coating liquid is supported. It consists of a rotatable support 3 and an active energy ray irradiator 4 that irradiates the dental restorative component 2 to be supported on the support 3, such as an ultraviolet lamp or/and an infrared lamp. There is.

In the present invention, the box 1 is designed to prevent active energy rays generated from the active energy ray irradiator 4 inside the box from escaping to the outside of the box 1, and to prevent dust when processing repair parts. , made of opaque material such as metal, plastic, or wood so that it can be sealed.

Preferably, among the materials, the active energy ray irradiator 4
In the present invention, it is preferable to use a heat-resistant material such as metal in order to withstand the generated heat.
It is necessary to attach an opening/closing door 11 that allows the support body 3 supporting the support body 3 to be attached to the joint 5 or to be taken out.

Further, the box 1 can be provided with air supply holes 9, 9' on the side surfaces thereof to change the atmosphere inside the box 1, for example, to a nitrogen atmosphere, if necessary.

It is preferable that the box 1 be manufactured to a size convenient for portability.

A plurality of supports 3, which support the repair member 2 at their tips and rotate around their axes, are driven by a drive device provided at the lower part of the box 1, for example, as shown in FIGS. 1 and 2. It can be rotated by a motor 7, a bearing 13, a pulley 12, a gear 6, etc., respectively.

The support 3 may be of various types depending on the size, shape, processing method, etc. of the repair member 2 to be processed, such as a rod-shaped support as shown in Fig. 3 a and b, or a support as shown in Fig. 3 C. A ramp-shaped support can be used.

Moreover, these bearings can be easily replaced by a joint 5 mechanism as shown in FIG. 3a.

In the present invention, as shown in FIG. 2, when the reflector 8 is provided below inside the box 1, the reflector 8 is installed so that the tip of the support 3 is above the reflector 8. need to be penetrated.

The active energy ray irradiator 4 provided in the box 1 is not particularly limited as long as it generates active energy rays, but may be a lamp that generates ultraviolet rays such as a high pressure mercury lamp or a medium pressure mercury lamp, an infrared lamp, or a far-field lamp. Lamps that generate infrared rays, such as infrared lamps, are preferred.

A suitable mounting position for the active energy ray irradiator is above the repair member 2 that is supported by the support and is to be processed.

Further, as the lamps used as active energy irradiators, one or more ultraviolet light emitting lamps, infrared light emitting lamps, etc. may be combined in the same box 1.

In order to more efficiently irradiate the surface of the repair member with the active energy rays generated by the active energy ray irradiator, one or more reflecting plates 8 may be provided, but it is possible to provide one or more reflecting plates 8, but it is possible to provide a reflector plate 8 such as a spheroidal concave mirror that directs the light to one point. A concentrated one is rather undesirable for the apparatus intended for the present invention, since it is not possible to process a plurality of repair parts at the same time.

Depending on the repair member, the supporting body may be used while remaining stationary without being rotated.

An example of the method of using the present invention will be described in the case where coating processing is performed using both ultraviolet light and infrared light.

First, the repair member 2 is placed on the support 3, and a coating liquid is applied by brush painting, dipping, etc., and the repair member 2 is attached to the joint 5.

After closing the opening/closing door 11 and sealing the box 1, the inside of the box 1 is filled with an inert gas such as nitrogen gas, if necessary.

The output of the infrared lamp 4 is adjusted according to the material of the repair member 2.
Adjust with the infrared lamp output regulator 14.

Next, the infrared lamp 4 and the ultraviolet lamp (not shown) are turned on while the support is rotated by the motor 7 at the required number of rotations, and the coating film of the repair member 2 is irradiated with infrared rays and ultraviolet rays for a predetermined period of time. Harden.

The present invention as described above is efficient because it is equipped with a support that can process a plurality of repair members 2 at the same time, and can process a large number of repair members 2 at the same time. Since it can be rotated dynamically by a motor, it can irradiate active energy rays efficiently and uniformly. Moreover, it is convenient to carry, so it can be immediately processed to match the tooth shape during patient treatment, and the result It can produce extremely useful effects such as greatly shortening treatment time.
