Description

The present invention relates to a metal bed used for a denture, a denture using the same, and a method for rebasing a metal bed in a denture.
More specifically, the present invention relates to a structure in which a connecting means or a connecting portion with a resin floor is not provided on the back side of an artificial tooth.
Further, the present invention relates to a denture provided with a metal floor that enables easy rebasing for reusing an artificial tooth.

  For example, when all teeth are lost, a complete denture composed of an artificial tooth and a denture base is used as the denture. The denture base that constitutes this complete denture consists of a resin floor made entirely of resin, and a part that touches the ceiling (palate) is formed of a metal floor, and the other parts are Some are made up of resin floors.

  Dentures made entirely of a resin base have the advantage that they can be manufactured relatively easily, but because the parts that touch the palate have to have the required thickness, they feel uncomfortable when worn. There is a drawback that is likely to occur.

On the other hand, a denture having a metal floor is expensive because the manufacturing process is complicated, and has a disadvantage that the weight of the denture itself increases.
However, since the part in contact with the palate can be formed thinly, all have a better feeling than the resin floor, and the heat feeling is also excellent, so that the taste is not impaired, and further, it has the advantage that it does not affect the pronunciation function. .
In general, it is said that the one with a metal floor has more advantages and is superior to one that is entirely a resin bed.

Dentures that are all resin bases are usually manufactured through the following steps.
A wax denture with artificial teeth attached (the gingival part supporting the artificial teeth is made of wax) is placed in one container of a flask (a metal container for injecting liquid gypsum and resin). It is buried and fixed in gypsum that has not solidified.
One container of the flask is attached with the other corresponding container, and gypsum is poured into the flask.
After the gypsum has hardened, heat is applied to the flask with hot water, and the wax supporting the artificial teeth is poured out of the flask (lost wax method).
The resin is injected into the void in the flask formed by the wax.

Moreover, the denture 9 provided with the metal floor 90 is also manufactured through substantially the same process (see FIGS. 17, 18, and 19).
A wax denture having no portion in contact with the palate and a metal floor 90 in contact with the palate are temporarily integrated by providing wax.
The metal floor 90 is provided with a net-like coupling portion 900 (also referred to as a skeleton) protruding around a portion in contact with the palate (see FIG. 16). Since the resin is not chemically bonded to the metal, the bonding portion 900 is for physically bonding the resin and the metal by covering the resin with the resin. The metal floor 90 is integrated with the wax denture by covering the joint portion 900 with wax.

An integrated wax denture and a metal bed 90 are buried and fixed in a plaster that has not yet solidified, provided in one container of the flask.
The other container is attached to one container of the flask, gypsum is poured into the flask, and after setting, heat is applied with hot water and the wax is poured out.
The resin is injected into the void portion in the flask formed of wax, and the resin is allowed to enter the network of the joint portion to physically bond the metal bed 90 and the resin.

  The dentures manufactured in this way stick to the loose part of the teeth and the mucous membrane of the palate so that they do not move or disengage via saliva.

However, since the condition in the oral cavity changes with age, the portion of the denture that comes into contact with the palate gradually becomes unsuitable, and becomes easier to come off.
Dentures that do not fit must be re-based (which refers to the process of matching the denture base to the new mucosa shape while leaving the artificial teeth intact) or have to be remade.

  Dentures that have a denture base entirely made of resin are made of resin at the part that contacts the palate, and since the resins are chemically bonded to each other, by adding a new resin to the mucosa side of the dentures that do not fit, Rebasing is relatively easy.

However, those provided with the metal floor 90 cannot be rebased by the above-described method because the metal and the resin are not chemically bonded.
A method of removing the metal floor 90 that has become unsuitable and integrating the newly formed metal floor and the remaining resin floor 91 so as to match the shape of the palate is also conceivable. In fact, this method is also difficult because the portion that overlaps with the back side (base portion) of the artificial tooth 92 of the floor 91 is physically coupled and cannot be removed (see FIGS. 17 and 18).
In other words, the denture 9 provided with the metal floor 90 is difficult to rebase itself, and if it does not fit, it is almost always remade.

(Work)
ADVANTAGE OF THE INVENTION According to this invention, the denture which prevented the coupling | bonding means or coupling | bond part with a resin bed from being provided in the back side of an artificial tooth can be manufactured. The denture is not provided with a metal floor coupling means or coupling portion on the back side of the artificial tooth, so nothing is left on the side of the resin bed even if it is removed. Therefore, the denture can be easily rebased. That is, according to the present invention, it is possible to manufacture a denture that can be easily rebased even though it has a metal floor.

  The coupling means or the coupling portion is provided at the edge, and is configured to include a space portion that holds a part of the resin bed in the interior. By inserting the part, the metal floor and the resin floor can be joined together.

  What is formed so that the space portion is provided between the upper edge portion and the lower edge portion is that the resin enters the space portion, so that the resin floor is sandwiched between the portions, so that the metal The floor does not come off in the vertical direction of the resin floor.

  If the edge shape of the upper or lower edge constituting the holding means is formed so as to enter or exit inward or outward, or substantially inward or outward, the resin floor is recessed in the inwardly recessed part. It is provided so that it may enter into a slender part, and the part which bulges outward is provided so that it may enter into a resin floor. This prevents the metal floor from sliding off in the lateral direction because these portions of the resin floor themselves become resistive.

(A) According to the present invention, it is possible to manufacture a denture in which the means for joining with the resin bed or the joint portion is not provided on the back side of the artificial tooth. The denture is not provided with a metal floor coupling means or coupling portion on the back side of the artificial tooth, so nothing is left on the side of the resin bed even if it is removed. Therefore, the denture can be easily rebased. That is, according to the present invention, it is possible to manufacture a denture that can be easily rebased even though it has a metal floor.

(B) The connecting means or the connecting portion is provided at the edge, and the space is formed by holding a part of the resin bed inside and holding the resin. By putting a part of the floor, the metal floor and the resin floor can be joined together.

(C) What is formed so that a space part is provided between an upper edge part and a lower edge part is in the state which pinched | interposed the resin floor in this part because resin enters in a space part. Therefore, the metal floor does not come off in the vertical direction of the resin floor.

(D) If the edge shape of the upper edge or lower edge constituting the holding means is formed so as to enter or exit inward or outward, or substantially inward or outward, a resin is not provided in the inwardly recessed part. The floor is provided so as to enter the recessed part, and the part bulging outward is provided so as to enter the resin floor. This prevents the metal floor from sliding off in the lateral direction because these portions of the resin floor themselves become resistive.

Embodiments of the present invention will be described in more detail with reference to the drawings.

4 is a cross-sectional view of the denture shown in FIG.
FIG. 5 is a cross-sectional view of the denture shown in FIG.
In the present embodiment, a maxillary complete denture will be described as an example of a denture.

  The code | symbol G has shown the denture. The denture G includes an artificial tooth 1 and a denture base 2. The denture base 2 is configured by providing a resin floor 21 around a metal floor 20 that is in contact with the palate (see FIG. 1).

The metal floor 20 will be described in detail (see FIG. 2).
The metal floor 20 is formed in a thin plate shape having a rounded edge portion located on the front tooth side and having a curved surface curved upward so as to match the shape of the patient's palate.
A resin coupling portion 200 that is a coupling means or a coupling portion is formed at the edge of the metal floor 20. In the resin coupling part 200, a thin plate constituting an edge part is separated into an upper edge part 205 and a lower edge part 206, and a space part 201 is provided therebetween. Thereby, when integrating with the resin floor 21, a part of resin which comprises the resin floor 21 can enter the space part 201. FIG. In the present embodiment, the space 201 is formed by forming the upper edge 205 and the lower edge 206 in a substantially “>” (or “<”) cross section (see FIG. 4). However, the cross-sectional shape is not limited. For example, the cross-sectional shape may be a substantially “U” shape, the cross-sectional shape may be a “V” shape, the cross-sectional shape may be a “U” shape, or a similar shape.

As shown in the bottom view and the BB end view, the lower edge portion 206 constituting the resin coupling portion 200 is provided with a plurality of concave portions 202 so that the edge shape enters and exits inward and outward so as to have a so-called waveform shape. It is formed (see FIGS. 2, 3, and 5).
Further, the upper edge 205 and the lower edge 206 constituting the resin coupling part 200 are formed so that the base side is narrowed inward (see FIG. 3).

  The denture G is formed by integrating the resin floor 21 having the artificial teeth 1 and the metal floor 20 by solidifying the resin constituting the resin floor 21 into the space 201 of the resin coupling portion 200 so as to be fitted. Has been. In this state, the resin coupling portion 200 is located inside the artificial tooth 1 provided outside the metal floor 20. At this time, the upper surface of the resin floor 21 is substantially flush with the upper surface of the upper edge 205 constituting the resin joint portion 200 of the metal floor 20, and the lower surface of the resin floor 21 is the lower surface constituting the resin joint portion 200. It is substantially flush with the lower surface of the edge 206.

With reference to FIG. 6 thru | or FIG. 13, an example of the manufacturing method of the metal floor 20 is demonstrated.
FIG. 6 is a perspective explanatory view showing a state in which a wax material for forming the upper edge portion of the resin holding portion is provided at a required position of the plaster mold,
FIG. 7 is a longitudinal sectional view of the plaster mold shown in FIG.
FIG. 8 is a perspective explanatory view showing a state in which a masking material is provided on the wax material shown in FIG.
FIG. 9 is a longitudinal sectional view of the plaster mold shown in FIG.
FIG. 10 is a longitudinal sectional explanatory view showing a state in which wax dentures and the like are temporarily fixed to a plaster mold, and the plaster is raised on the wax material shown in FIG.
FIG. 11 is a perspective explanatory view showing a state in which a wax material for forming a lower edge portion of the resin holding portion and a portion in contact with the palate is provided,
FIG. 12 is a longitudinal sectional view of the plaster mold shown in FIG.
FIG. 13 is a longitudinal sectional explanatory view showing a state in which a gypsum mold that is paired with the gypsum mold shown in FIG. 12 is provided.

  First, the impression of the patient's upper jaw is collected using an impression material to form a plaster mold. In addition, the curved curved surface part of the gypsum type | mold shown by the code | symbol 601 in FIG. 6 is the part which modeled the shape of the patient's palate. Moreover, the code | symbol 5 shown in FIG. 6 thru | or FIG. 13 has shown the runner for pouring the molten metal.

  A sheet-like wax material 40 for forming the upper edge portion 205 of the resin coupling portion 200 is provided on the inner portion of the bank portion 600 of the formed plaster mold 60 (see FIGS. 6 and 7). The brazing material 40 is provided on the bank portion 600 so as to have a substantially “U” shape in plan view.

  A masking material 41 having a required width is provided on the inner edge side of the wax material 40 (see FIGS. 8 and 9).

  On the bank portion 600 of the plaster mold 60, the wax denture 3 provided with the artificial tooth 1 (shown later, but at the time of rebasing, the portion remaining after removing the metal floor of the denture G) is temporarily fixed. Gypsum 42 for forming the space 201 of the resin coupling portion 200 is placed on the wax material 40 (see FIG. 10). The gypsum 42 is smoothly continuous with the surface of the part of the temporarily fixed wax denture 3 that is shaped like the gum 30 and is substantially flush. At this time, the gypsum 42 should not be deposited on the masking material 41.

  After the plaster 42 has hardened, the masking material 41 is removed, and an outline 43 that determines the edge position of the lower edge 206 of the resin joint 200 is written on the surface of the plaster 42 with a pen or the like. The outline 43 is not particularly limited as long as it is a position that does not interfere with rebasing at a portion corresponding to the inside of the bank portion 600. In the present embodiment, the bottom portion of the concave portion 202 is set to be substantially at the same position as the outer edge of the wax material 40.

  On the plaster 42 and on the curved surface portion 601 surrounded by the plaster 42, a sheet-like brazing material 44 for forming a lower edge portion 206 of the resin coupling portion 200 and a portion in contact with the palate is provided (FIG. 11, FIG. 11). (See FIG. 12). The brazing material 44 is cut out from the outer shape line 43 with a cutter or the like. In addition, although the wax material 44 used what has transparency so that the outline 43 can be seen through, this is not limited.

  Finally, a gypsum mold 60 provided with a wax material 44 is placed in a container 65, and gypsum for forming a gypsum mold 61 as a pair is injected into the container 65 (see FIG. 13). Specifically, the gypsum mold 61 is formed so as to wrap the gypsum mold 60. After the gypsum has hardened, the gypsum molds 60 and 61 are immersed in hot water or the like to apply heat to melt the wax materials 40 and 44 and flow out from the runner 5 or a discharge hole (not shown). Thereby, a mold for casting the metal floor 20 is formed.

  Then, liquid metal melted from the runner 5 is poured into the gypsum molds 60 and 61. Thereby, the metal floor 20 is manufactured.

  Note that the metal floor 20 is not limited to be manufactured using the mold manufactured by the above-described method, and can be manufactured using a mold manufactured by another method. In addition, the metal floor is not particularly limited to manufacture by casting, and can also be manufactured by, for example, pressing or the like other than casting.

Next, with reference to FIG. 14 thru | or FIG. 16, an example of the manufacturing method of the denture G using the metal floor 20 is demonstrated.
FIG. 14 is a bottom view showing a state in which wax is provided between a metal floor and a wax denture, and the metal floor and the wax denture are temporarily integrated;
FIG. 15 is a cross-sectional explanatory view showing a state in which the metal floor and wax denture shown in FIG. 14 are integrated in a flask.
FIG. 16 is a cross-sectional explanatory view showing a state in which a resin is injected into a void portion in a flask formed of wax.
Note that the reference numerals in parentheses shown in FIG. 14 and FIG. 15 will be described in the rebase method of the metal floor in the denture G described later.

  First, a wax 70 is provided between the metal floor 20 and the wax denture 3 so as to fill the space 201 of the resin joint portion 200, and the metal floor 20 and the wax denture 3 are temporarily integrated (see FIG. 14). The upper surface of the wax 70 is substantially flush with the upper surface of the gum 30 of the wax denture 3 and the upper surface of the upper edge 205 constituting the resin joint portion 200 of the metal floor 20, and the lower surface is the gum of the wax denture 3. 30 and the lower surface of the lower edge portion 206 constituting the resin coupling portion 200 are substantially flush with each other. This integration is usually done manually but is not limited.

What integrated the metal bed 20 and the wax denture 3 is buried and fixed in the plaster 800 which has not yet solidified provided in one container 80 of the flask.
One container 80 of the flask is attached to the other container 81, and gypsum 810 is poured into the flask (see FIG. 15).

  After the gypsum 810 has hardened, the flask is immersed in hot water or the like to apply heat, and the wax constituting the wax denture 3 is integrated with the metal floor 20 and the wax denture 3, and the resin joint portion The wax 70 filled in the space 201 of the 200 is poured out from the flask through a runner (not shown) or a discharge hole (not shown). In this state, the artificial tooth 1 and the metal floor 20 remain in the flask.

  Resin is poured from the runner into the gap 66 in the flask formed by the wax that has flowed out, and the resin enters the space around the artificial tooth 1 and the space 201 of the metal floor 20 to form the resin bed 21. In this way, the artificial tooth 1 and the metal floor 20 are integrated by the resin floor 21, and the denture G is manufactured.

The metal floor 20 constituting the denture G does not include the overhanging mesh-like connecting portion provided in the conventional metal floor.
However, the metal floor 20 has the resin in the space 201 of the resin coupling portion 200 formed at the edge, so to speak, the resin floor 21 is sandwiched between these portions, so the vertical direction in FIG. Never go off.

  Further, the metal floor 20 has a concave portion 202 formed at the lower edge portion 206 constituting the resin coupling portion 200, and a convex portion 210 is formed on the back tooth side so that the resin floor 21 corresponds to the concave portion 202. (See FIG. 5), the base side of the resin coupling part 200 is formed to be inwardly squeezed inward, and the resin floor 21 is filled in this part so that the engaging part 211 is formed. (See FIG. 3), the convex portion 210 and the hooking portion 211 themselves become resistance, and do not slide off in the lateral direction in FIG.

The denture is only attached to the loose part of the tooth or the mucous membrane of the palate via saliva, so it is desirable that it is as light as possible to prevent it from falling off.
The denture G can be lighter than the conventional one because the metal floor 20 does not have the overhanging connecting portion that the conventional metal floor has.

  As described in the section of the prior art, the rebase of the denture G having the metal floor 20 removes the metal floor that has become unsuitable, and the newly formed metal floor 20 and the remaining resin floor 21 are integrated to match the shape of the palate. It can be implemented if possible.

  Since the denture G uses the metal floor 20 in which the joint portion is not overhanging, even if the metal floor 20 is removed, the remainder can be prevented from remaining on the resin floor 21. Therefore, as shown below, if the resin floor 21 provided with the artificial teeth 1 and the metal floor 20 are separated and the metal floor 20a formed so as to be newly fitted and the resin floor 21 are integrated, rebasing is possible. (See FIG. 14).

A method for rebasing the metal floor in the denture G will be described with reference to FIGS. 14 and 15 described above.
First, the metal floor 20 that has become unsuitable is removed. The metal floor 20 is removed by cutting the resin floor 21 with a cutter or the like along the edge of the resin joint portion 200.

  Between the new metal floor 25 and the resin floor 21 from which the metal floor 20 has been removed, a wax 71 serving as a solid bonding means is provided so as to be filled in the space 201 of the resin joint 200, The resin floor 21 is temporarily integrated.

  The metal bed 25 and the resin bed 21 are integrated into one container 80 of the flask, which is buried and fixed in a gypsum 800 that has not yet solidified, and the other container 81 is covered and attached. Inject gypsum 810 into

  After the plaster 810 has hardened, the flask is immersed in hot water or the like to apply heat, and the new metal floor 25 and the resin floor 21 are integrated, and the space 201 of the resin joint 200 is also filled. The wax 71 that has been removed is poured from the flask through a runner (not shown) or a discharge hole (not shown).

  Resin is injected into the gap 67 in the flask formed by the wax 71 that has flowed out, and the resin enters the space 201 of the resin joint 200 of the metal bed 25 to form the resin bed 21. Since the injected resin is chemically bonded to the remaining resin floor 21, the resin floor 21 and the metal floor 20 a are thereby integrated, and the denture G is rebased.

  Thus, according to the denture G, although it has a metal floor, it can be easily rebased. Therefore, the patient's worry that “the denture base is all superior in performance to that of the resin bed but cannot be used due to difficulty in rebasing” can be eliminated.

  The terms and expressions used in this specification are merely explanatory and are not limiting at all, and exclude terms and expressions equivalent to the features described in this specification and parts thereof. There is no intention to do. It goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
