BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate preferred embodiments of the invention and, together with the description, serve to further the understanding of the technical idea of the invention, It should not be construed as limited.
FIG. 1 and FIG. 2 are flowcharts sequentially showing the steps of manufacturing a fixed prosthesis according to an embodiment of the present invention.
3 is a view illustrating the structure of a support according to an embodiment of the present invention.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. In addition, the embodiment described below does not unduly limit the content of the present invention described in the claims, and the entire structure described in this embodiment is not necessarily essential as the solution means of the present invention. In addition, the description of the prior art and those obvious to those skilled in the art may be omitted, and the description of the omitted components and the function may be sufficiently referred to within the scope of the technical idea of the present invention.

The diagnosis sensor including the RFID according to an embodiment of the present invention is attached to a fixed prosthesis (for example, a tooth, an implant, a crown, or a pocelain) of a user to diagnose inflammation caused by the attachment of the fixed prosthesis, Diagnosis of the user's health condition by analyzing the needle, and transmitting the diagnosis result to an external terminal (e.g., smart phone or tablet PC). The diagnostic sensor including the RFID can automatically transmit the information recorded in the RFID when the external terminal approaches within a certain distance by adding the NFC function.

The diagnostic sensor with RFID stores the result of the diagnosis of irritation or the result of analyzing the needle, and in particular, the date and the date of fixing prosthesis, the user name, the medical treatment clinic, and the patient treatment history can be stored. Such a diagnostic sensor with RFID can have a size corresponding to the size of the fixed prosthesis. That is, since the size of the teeth is different for each user and the sizes of the teeth are different depending on the position of the user's teeth, the sizes of the diagnostic sensors including RFIDs can be manufactured for each tooth type. The following steps are performed to implant (or insert) the diagnostic sensor with RFID into the fixed prosthesis. In the case of an implant, a crown or a porcelain or the like may be attached to the top of the implant after the implant is implanted. Hereinafter, a crown and a porcelain will be described as an example. Other fixative prostheses or dentures may be applied as needed.

(Burying method of diagnostic sensor with RFID - Example )

A method for embedding a diagnostic sensor having an RFID in a crown according to the first embodiment of the present invention performs the following steps. However, the process of manufacturing the pocelain with the same color as that of teeth using the PFM (Porcelain Fused to Metal) material after the crown is further performed, but the process of burring the diagnostic sensor with RFID is the same.

The crown manufacturing method will be described below to explain the steps for embedding the diagnostic sensor having RFID into the crown according to the present invention. In the present invention, May be referred to in the prior art within the scope of not departing from the scope of the present invention.

First, referring to FIGS. 1 and 2, a process of burying a diagnostic sensor having an RFID in a crown will be described. The dental clinic removes a patient's tooth pattern from a dental clinic and is transferred to a dental laboratory. In the following example, the impression of the patient is shown. The dental laboratory performs a step of cleaning the impression body to remove impurities from the delivered impression body (S10).

Next, a blast furnace is mixed to inject the blast furnace into the impression body, and then the blast furnace is carefully injected into the impression body so as to prevent the air bubbles from flowing into the impression body (S20).

Next, after the hard stone is hardened on the impression body, the work model is separated from the impression body, and the work model is trimmed to meet the requirement (S30). At this time, the work model refers to the portion of the impression body where the hard stone is hardened, and the work model has the same shape as the actual patient's teeth.

Next, a pin hole is formed on the lower surface (the surface opposite to the tooth-formed surface) of the work model using a drilling mechanism, and a dowel pin is attached to the pin hole using an adhesive (S40). The attached pin is formed on the underside of the tooth where the actual crown is made.

Next, the operation model is placed in the mold, the hard stone is poured to make the base, and the base is hardened and then the base is trimmed (S50).

Next, the teeth to be crowned are sawed to separate from the work model, the separated teeth are trimmed, and margins are trimmed to form a certain margin (S60). At this time, one tooth may be separated or a plurality of teeth may be arranged as needed. The teeth separated into one or plural teeth are formed into crown through the steps described below, and the manufactured crown is transferred to the dental clinic and attached to the patient's teeth.

Next, since there is a risk of breakage of the separated tooth profile, a hardener is applied to the separated tooth profile, and a spacer is applied (S70) to provide a space for accommodating the cement.

Next, the occlusal state of the other occlusion (corresponding to the lower occlusion of the tooth, for example) and the corresponding occlusion (corresponding to the upper occlusion of the tooth, for example) S80).

Next, the separating agent is applied, the wax is waxed up to the separated tooth shape, the wax is filled, and the overflowing portion is re-sculpted so that the occlusion and the occlusion are adjusted to match the occlusion and the margin Step S90). At this time, since the wax-up step is sensitive to temperature, the wax-up operation is preferably performed in a warm place. The wax that is piled up in the separated tooth form is melted down in the summoning work later, and the gold (gold) enters into the melted space and forms the crown.

Next, the main cutting line is sprued so that gold is injected, and a support is attached to the peripheral surface of the waxed up tooth so as to secure a space for the diagnostic sensor having the RFID to be buried in the crown (S100). At this time, it is preferable to use a material that does not dissolve at high temperatures, that is, an asbestos-based material. More specifically, a waxed up tooth having a main line and a support is inserted into the casting ring, and a gypsum is injected into the casting ring, the waxed up teeth and the support are supported in the casting ring by the gypsum (S110). When the heat is applied at a high temperature by a summoning operation to be described later, the wax-like tooth-shaped wax is melted down and gold is injected into the space of the wax melted along the main line to form a crown. At this time, the supporting table is not melted by the summoning operation, and a space for inserting the diagnostic sensor having the RFID is formed in the circumferential direction of the side of the crown by the support. The casting ring is substantially cylindrical, and the upper surface is an open space, in which gypsum is injected, and gold is injected into the rear surface of the casting ring by connecting the main line. The lead line provides the path through which gold is injected, which can be of various shapes and can provide multiple paths through which gold is injected. The shapes of the injection lines may be various shapes and shapes within the scope of the technical idea of the present invention.

3, a supporting base attached to one of the circumferential surfaces of the wax-up toothed-up tooth forms a space for inserting a diagnostic sensor having an RFID, and the supporting base 100 has a wax- A circumferential surface attachment portion 110 attached to the circumferential surface, and a support portion 120 configured to support the circumferential surface attachment portion. The circumferential surface attachment portion 110 is attached and fixed to the circumferential surface of the wax-up tooth, and an insertion hole into which the diagnostic sensor having the RFID is inserted is formed by the thickness of the circumferential surface attachment portion 110. In other words, when the gypsum is poured in the casting ring and summoned, the wax melts down and gold is injected into the melted wax space to form a crown. At this time, an insertion hole into which the diagnostic sensor having RFID is inserted can be formed in the crown as much as the thickness (width) and length of the circumferential surface attachment portion 110. However, it is preferable that the shape and size of the circumferential surface attachment portion 110 correspond to the circumferential surface shape and size of the waxed tooth profile. In other words, the waxed teeth may have various shapes and sizes depending on the individual, and it is preferable that the circumferential surface attachment portions 110 are formed to match the various wax-up teeth. Generally, It is preferable that the cross-section of the surface to be attached to the waxed tooth profile is formed to be a curve rather than a straight line.

The supporting portion 120 supports the circumferential surface attachment portion 110 to be fixed to the waxed tooth form, and the circumferential surface attachment portion 110 is firmly supported together with the gypsum because the gypsum is injected into the casting ring. Accordingly, the support portion 120 may be formed in various shapes that can support the circumferential surface attachment portion 110 in addition to the shape shown in FIG. 3, without departing from the technical idea of the present invention.

Next, a burn-out operation is performed in order to remove moisture in the wax and investment material (or plaster) used in the waxed-up tooth-type (or lead-type) production (S120). (Casting step) so that the wax melts down by applying high temperature heat to the casting ring and gold is injected along the main entrance line between the spaces to form the casting body (casting step) An insertion hole into which a diagnostic sensor having an RFID is inserted is formed by a size and a width of the insertion hole (S130).

Next, the casting body is washed, and the casting body is polished by a polishing operation (S140).

Next, a diagnostic sensor having an RFID is inserted into the insertion hole and closed using a transparent resin so that a diagnostic sensor having RFID is attached to one surface of the circumference of the crown (S150).

(Burying method of diagnostic sensor with RFID - second Example )

In the first embodiment, an insertion space for inserting a diagnostic sensor having an RFID is formed by using the support 100. The second embodiment is similar to the first embodiment except that the support 100 is not used in manufacturing the zirconia prosthesis, During the crown making process, the insert hole is formed by drilling at a predetermined stage.

The configuration and functions of the above-described components have been described separately from each other for convenience of description, and any of the components and functions may be integrated with other components or may be further subdivided as needed.

Although the present invention has been described with reference to the embodiment thereof, the present invention is not limited thereto, and various modifications and applications are possible. In other words, those skilled in the art can easily understand that many variations are possible without departing from the gist of the present invention. In the following description, well-known functions or constructions relating to the present invention as well as specific combinations of the components of the present invention with respect to the present invention will be described in detail with reference to the accompanying drawings. something to do.
