ある。Detailed Description of the Invention [Industrial Application Field] The present invention relates to a novel opaque means for resin jacket crowns for dentures, and replaces the conventional opaque means by applying a paste-like opaque material to a synthetic resin jacket crown of a constant thickness. It is characterized in that the opaque effect can be easily obtained by heat-molding a resin sheet on the abutment tooth.

態に仕上げるという手法が一般的であった。Opaque, which is indispensable in manufacturing resin jacket crowns for dentures (hereinafter simply referred to as "jacket crowns"), has until now been used as an abutment tooth of a plaster model (tooth mold to be restored).
A separating agent is applied to the surface of the opaque layer, and then a paste-like opaque material is applied and cured.In addition, the jacket crown is coated with cervical material, dentin material, enamel material, etc. to the desired color tone on the surface of the opaque layer. The common method was to apply a paste resin and build it up while curing it by heat or photopolymerization, and finish it into the desired shape of the denture.

見られたものである。Conventional methods for applying opaque are as follows: - It is difficult to obtain an opaque layer with a uniform thickness by multiple coatings, and in order to prevent color spots caused by this, and especially in the photopolymerization method, opaque materials are used due to limitations on curing depth. In order to ensure reliable hardening, the coating and curing process must be repeated two or three times, and this process requires a lot of effort and time.

技術的課題を解決したものである。In view of these circumstances, the present invention proposes that when producing a jacket crown, instead of applying the paste-like opaque material described above, a synthetic resin sheet of a certain thickness is heated and softened to tightly adhere to the surface of the abutment tooth of the plaster model. This method solves the technical problems of conventional opaque means by forming an opaque layer and then building up a resin layer on its surface in a conventional manner.

材等のレジン層である。Hereinafter, the configuration of the present invention will be described in more detail according to one embodiment. In FIG. 1, 1 is a plaster model, 2 is an abutment tooth, and 3 is a plaster model.
4 is an opaque layer formed by closely covering the surface of the abutment tooth 2 with an acrylic resin sheet, or 4 is a resin such as dentin material or enamel material built up on the surface of the opaque layer 3 by a conventional method. It is a layer.

宜選択することが好ましい。The opaque layer in the above embodiment was shown to be composed of an acrylic resin sheet with a thickness of 0.2 mm, but the sheet thickness by the opaque means of the present invention is usually 0.1 to 0.4 mm.
Although this range is appropriate and this does not preclude the use of thermoplastic synthetic resin sheets other than acrylic, it is preferable to select the material of the sheet as appropriate depending on the properties of the resin material to be applied.

待できるものである。As described above, according to the opaque means in the jacket crown of the present invention, by simply applying a synthetic resin sheet of a certain thickness to the surface of the abutment tooth to be restored by heating and softening it, the thickness and physical properties are always uniform. A stable opaque layer is reliably molded, and the work is extremely simple and can be done in a short time, which is a remarkable effect.In addition, since the opaque layer is a synthetic resin sheet, it is possible to mold the abutment tooth without using a separating agent. The jacket crown can be easily removed from the plaster model without sticking to the surface, and since the opaque layer is finished with a uniform thickness, the color tone of the denture can be reproduced by the resin material built up on the surface. A variety of excellent effects can be expected, such as ease of use.
この他、本発明のオペーク手段によれば、次のような付
帯的効果も期待できる。In addition, according to the opaque means of the present invention, the following additional effects can be expected.
■ 化学的重合を必要とするオペーク材は、重合前の長
期保管に対して安定した物性が保障されず、経時的に変
質を生ずるが、合成樹脂シートには、そのような不都合
がない。■ Opaque materials that require chemical polymerization cannot guarantee stable physical properties during long-term storage prior to polymerization and deteriorate over time, but synthetic resin sheets do not have such disadvantages.
■ レジン塗布によるオペーク層は、口腔内でのモノマ
ーの溶出によって生体に悪影響を及ぼす恐れが考えられ
るが、合成樹脂シートでは、そのような危険性はない。■ Opaque layers formed by resin coating may have a negative effect on living organisms due to the elution of monomers in the oral cavity, but synthetic resin sheets do not pose such a risk.
■ 分離剤を使用しなければならなかった従来のオペー
ク手段では、分離剤の選択から塗布、乾燥までに多大の
手数と時間を要したが、本発明ではそれらの作業が完全
に省略できる。(2) Conventional opaque means that required the use of a separating agent required a great deal of effort and time from selecting the separating agent to applying it and drying it, but with the present invention, these operations can be completely omitted.
■ 合成樹脂シートは、オペークのシェードガイドの働
きをするので、義歯に合った色調の選択が容易である。■ The synthetic resin sheet acts as an opaque shade guide, making it easy to select the color that matches your dentures.
