 The present invention relates to a dental prosthetic restoration, the restorative surface of the proximal teeth (8) of the lost teeth as a fixing means for restoring the restoration of metal or ceramic, etc. in order to restore the function of the missing teeth, Delete the insertion type holding part so that the recessed part can be inserted into the V-shaped, U-shaped, scratch-type or pin hole. In this case, the recessed retaining portion may have a different length, deletion form, deletion region, and deletion range depending on the tooth, and a predetermined angle will be given to obtain more retaining force. And the size and shape of the buried retaining part may vary depending on the need of holding force.

 And even if there is a slight cut (under cut) of the holding portion can be easily attached to the adjacent teeth using the elasticity of the metal.

 Conventional prosthesis as a treatment method for the prosthetic restoration is a crown bridge, the crown bridge has a large amount of hemorrhoidal removal, it may be necessary to perform neurological treatment due to pulp degeneration after prosthetic repair or dimensional exposure during hemorrhoidal deletion. Hypersensitivity reactions occurred after prosthetic restoration, and it was impossible to find the previous occlusion pattern by deleting the adjacent occlusal surface. In addition, implant prosthesis is a method of fixing artificial teeth with screws after planting metal artificial roots, which requires a lot of time and expense, and has a limit in restoring even in cases of severe periodontal disease, osteoporosis, diabetes and blood diseases. There is a relatively weak side.

 In the present invention, there is a projection on the recessed holding portion to which the arch is attached. The present invention relates to a method of manufacturing a duplicate prosthesis by duplicating this model again and attaching a spruce with a waxing up on the duplicated model to perform investment, summoning and casting.

 In order to manufacture the conventional dental prosthesis, the waxing up was performed on this model, and it was detached from the model, buried with a sprue, cast, and then welded to the model. It was difficult.

 The present invention has been made in order to solve the above problems, the technical problem is how to maintain the retaining force by fixing the artificial tooth (5) to the adjacent tooth (8) almost without deleting the adjacent tooth (5). Where and how aesthetic needs are needed is how to solve the problem.

 Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

First of all, the structure includes an embedded retaining portion 1, a protrusion 9 formed on the embedded retaining portion 1, a male body 7 attached to the embedded retaining portion, and a self 61 formed on an artificial tooth 5. do.

The buried holding part 1 is limited to only the adjacent face that has been removed in accordance with retaining power and aesthetic demand (FIG. 6), and extends lingually from the deleted adjacent face (FIG. 4). In the case of extending to the buccal region (Fig. 5) or lingual and extending to the buccal region (Fig. 3). The recessed holding portion 1 may have a shape or size to be deleted depending on the size and position of the adjacent surface of the lost adjacent teeth 8. Deletion is formed to the extent that no abnormality is felt without anesthesia. At this time, the buried holding part (1) formed is 0.5mm ~ 2mm depth. Deletion of the recessed holding part 1 where anterior and aesthetic is required is done on the lingual and proximal surfaces (with or without occlusal surface) and the removal of the recessed holding part 1 of the premolar and molars is adjacent. Confined to the occlusal surface (with or without) occlusal only, or adjacent and lingual (with or without lingual occlusal) or buccal surface (with or without buccal occlusal), or adjacent to lingual, buccal (with or without buccal occlusal) ) Or the inlet 91 is formed at the end of the lingual and buccal region. At this time, the hole shape 23, the scratch shape 21 or the point-like hole 22 and the U-shaped shape 24, pin hole shape may be formed.

 A constant angle is given to the deletion site to increase the holding force of the embedded retention site 1. The holding part of the holding part varies depending on the required holding force (FIG. 8). In another method, the adjacent surface of the holding part may be formed with an inlet 91 having a predetermined angle at the end of the lingual and buccal areas without deletion (Figs. 15 and 16). The end of the adjacent teeth (8) is formed in the inlet port 91 is combined with the end portion of the lingual maintenance site (3), buccal maintenance site (4) to maximize the holding force (Fig. 15, 16). And where a lot of holding power is required, in order to obtain a wide holding area including the deleted face and the deleted adjacent part, the duplicated model is made in this model and then waxed up and waxed up on the duplicated model. Instead of removing one from the replica model, sprues are buried, burned out, cast and cast into this model. At this time, the degree of overprinting the removed surface and adjacent parts and buccal, lingual can be adjusted according to the shape and location of the tooth. Areas that do not require a lot of holding power are removed from waxing up after waxing up on this model, including those areas that have been removed and areas without under cut on the model. The replica model is unnecessary by attaching a sprue, burying it, burning it out, casting it, and then casting it onto the model. And where the holding force is rarely necessary, the prosthesis may be manufactured by obtaining the holding part using only the deleted part. And where the aesthetic face is required, the holding part may be placed only on the lingual side from the deleted adjacent face (FIG. 4) or the holding part only on the adjacent face (FIG. 6).

 Where the esthetic side is not important, the buried maintenance site 1 extends toward the lingual and buccal surfaces (FIG. 3). In addition, the buried maintenance site (1) may cover a portion of the occlusal surface without obstacles to the non-functional cusp and occlusion in order to obtain the maximum maintenance (Fig. 8). The arch body 7 attached to the recessed holding portion 1 is formed of I, L, O, T and other deformed shapes to obtain the maximum coupling force with the self 61 formed in the artificial tooth 5. Can be taken. And the buried body (7) attached to the buried retaining portion (1) and the buried retaining portion (1) to facilitate the insertion of the artificial teeth (5) by tightening the parallel to the missing adjacent abutment teeth and strengthen the bite resistance And lateral pressure. There is almost no tooth removal when recovering the lost tooth in the same way as above, so that the occlusal surface remains the same, so there is no need to worry about dimensional degeneration, dimensional exposure, clam change and hypersensitivity.

 The artificial tooth 5 can be repaired by ceramic, metal, or the like. By using the method as described above, the procedure is simple and can be repaired at low cost by eliminating the disadvantages of tooth removal and implant prostheses, which are disadvantages of conventional crown bridge prostheses.

 Since there is almost no anesthesia and tooth removal, it is free from the fear of dental treatment and can come to the hospital with a light mind. Prosthetic restoration can be performed without risk, even in patients with high blood pressure, angina, and anesthesia. Since there is little tooth removal, it does not affect the pulp so there is no need for hypersensitivity and neurotherapy after tooth restoration. Also, since there is little tooth deletion, the hardest part of our body, the enamel, is also preserved so that we can prevent the tooth from hurting. Since there is almost no occlusal surface deletion, the current occlusal state can be maintained and there is no change in the clathrate. And because the contact point is still maintained, the patient does not feel foreign. There is no soft tissue damage that can occur when teeth are removed. Inadequate tooth removal can melt the cement and prevent tooth deterioration. That can significantly reduce the occurrence of medical accidents. No anesthetic is required and patient treatment time is significantly shortened. Inevitable removal of the prosthesis is very easy. That is the most human-friendly prosthetic restoration method.
