Description

  The present invention relates to a wax occlusal embankment softening device. The wax occlusal embankment softening device according to the present invention can be used when softening a wax occlusion embankment in the course of producing a denture denture (so-called partial denture and total denture).

  An occlusal floor is used in the process of making a denture (a so-called partial denture and a total denture). The occlusal floor is a device used for recording the positional relationship between the upper and lower jaws of a patient with a denture, determining the occlusal position, and arranging artificial teeth (dentures). Each occlusal floor is a synthetic resin base floor. And an occlusal embankment made of wax.

  The foundation floor is a thin plate made of a cured resin molded from a plaster model of both upper and lower jaws taken from a denture patient with a mold as a mold. Specifically, the upper and lower jaw plaster models obtained by taking impressions from the mouth of denture patients with dentures are coated with uncured soft resin in a thin plate shape, and the jaw shape centered on the alveolar crest The upper surface has a horseshoe-shaped protrusion by an alveolar crest. On the other hand, the occlusal bank is formed by placing wax on the horseshoe-shaped protrusion on the upper surface of the foundation floor, and the upper surface is generally flat.

  The determination and adjustment of the occlusal position performed using the occlusal floors of the pair of upper and lower jaws prepared in this manner are usually performed by a dentist with respect to a patient in the dental clinic. For example, in the case of an edentulous patient, the upper surface of the upper occlusal levee was softened and corrected for the mandibular resting position, assuming a high diameter of the central occlusal position, and then the upper and lower jaws of the upper and lower occlusal floor It is possible to determine the occlusal height by attaching it to each part and engaging it.

In the determination adjustment of the occlusal position, it is necessary to soften the upper surface of the wax occlusion bank in the adjustment process of the vertical intermaxillary distance (meshing).
In the conventional vertical intermaxillary distance (meshing) adjustment process, for example, a metal spatula is heated with a burner, and the tip of the heated spatula is pressed against the wax occlusion dam to soften the wax occlusion dam Is used. However, in this method, since the heat capacity of the metal spatula is small, it is necessary to repeat the heating with the burner and the pressing to the wax several times alternately, and the work efficiency is poor. . In addition, if a spatula heated above the vaporization temperature of the wax with a burner is brought into contact with the wax, smoke and odor are generated, which not only pollutes the indoor air, but also causes discomfort and anxiety to the patient. It was a drawback.

  Moreover, as a wax occlusal embankment softening apparatus, an apparatus intended to soften a wide area of the upper surface of the wax occlusion bank at once and uniformly is known (Patent Document 1). FIG. 5 is a schematic perspective view of a conventional wax occlusal embankment softening device 90 described in Patent Document 1. As shown in FIG.

  As shown in FIG. 5 (a), in the softening device 90, a plurality of thin plate-like bodies 91 made of a heat conductive material are erected (standing) in parallel on the lower surface of a thick plate substrate 92 made of a heat conductive material. Furthermore, a decorative board 94 to which a handle 95 is attached is joined to the substrate 92 with a heat insulating material 93 interposed therebetween. A surface heater is provided inside the heat insulating material 93 so as to be in surface contact with the upper surface of the substrate 92, and the plate-like thin layer body 91 can be heated via the substrate 92. On the other hand, as shown in FIG. 5B, the occlusal floor 9 composed of the base floor 97 and the wax occlusion dam 98 is placed on the base plate 96 with the base floor 97 facing down, and the wax occlusion The plate-like thin layer 91 of the softening device 90 is brought into contact with the upper surface 98A of the embankment 98 by pushing it down in the direction of the arrow P with the handle 95, and further pushed down to a desired depth, thereby shortening the wax upper surface 98A of the occlusal embankment 98. Can be softened in time.

  This type of conventional softening device is intended to soften a wide area of the upper surface of the wax occlusal dam at once and uniformly, so that the tip portion contacting the upper surface of the wax occlusal levee forms an area. Moreover, the shape of each thin plate-like layered body is a rectangle. Therefore, this softening device is suitable for applications where it is necessary to soften a wide range of the upper surface of the wax occlusion bank by one operation, for example, the height adjustment process of the wax occlusion bank, It could not be adapted to applications that require partial softening of the area, such as applications that require height adjustment of a portion of the upper surface of the wax bite.

Further, when the softening device is brought into contact with the wax occlusal bank, the contact portion is hidden from the user's field of view, so that it is difficult for the user to check the contact state. Therefore, it is extremely difficult to grasp the end point of the softening of the wax occlusal levee, and there is a drawback that a part of the wax may be dropped due to being melted due to excessive heating.
Furthermore, since the softening device itself is large-scale, it is not suitable for being attached to each dental examination table, and it is also complicated to move it near the dental examination table. Therefore, when performing determination adjustment of the occlusal position, the occlusal floor frequently reciprocates between the patient on the dental examination table and the softening device, and the adjustment process itself is complicated.

Registered Utility Model No. 2596582

  Accordingly, an object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to partially soften a specific range of the upper surface of the wax occlusion bank, and to soften the entire upper surface of the wax occlusion bank in a short time. It is possible to directly observe the softening operation part of the wax occlusal embankment, and it is clean (without polluting the surroundings), small and safe without the complicated softening operation. Is to provide.

The problem is according to the invention,
(1) a base made of a thermally conductive material;
(2) Provided on at least one surface of the base, has a fan-shaped tip, a plurality of fin portions made of a heat conductive material, and (3) connected to the base via a connecting portion. This can be solved by a wax occlusal embankment softening device characterized by including a handle portion.

According to a preferred aspect of the apparatus of the present invention, heating means is provided inside the base.
According to another preferred aspect of the device of the present invention, the apparatus further includes a groove forming blade portion made of a conductive material on at least one surface of the base.
According to still another preferred aspect of the apparatus of the present invention, at least one surface of the base is a smoothing operation surface made of a conductive material.
According to still another preferred aspect of the device of the present invention, a plurality of fin portions whose maximum width and height of the fan-shaped tip portion are narrower than the width of the upper surface of the wax bite bank are parallel to each other, and the length of the base It arrange | positions on the base surface in 1 row in the direction.

  According to the softening device of the present invention, a desired specific range of the upper surface of the wax occlusal levee can be partially softened. For example, adjustment of the vertical intermaxillary distance and adjustment of the partial width of the occlusal levee Suitable for operation. In addition, the operation for softening the entire upper surface of the wax occlusal levee is relatively easy. Furthermore, since the part which is performing the softening process can be observed directly, there is no fear of overheating and melting, and an appropriate softening operation can be performed.

  Moreover, since the heat capacity of a base is large compared with the conventional method using a metal spatula, this invention does not require troublesome operation which repeats the same operation. In addition, if a heating means capable of temperature control is provided inside the base, the temperature can be controlled, and it is not necessary to use a gas burner. Further, by using the arc-shaped portion at the tip of the fan-shaped fin portion and the acute angle portions at both ends, the softening device is compared with a conventionally known softening device (for example, the softening device shown in FIG. 5 described in Patent Document 1). Thus, the fin portion can be pushed down from the upper surface of the wax occlusion bank to a predetermined depth with a smaller force. Furthermore, the device is small, and the attached tray can be used to quickly perform operations on the side of the patient on the dental examination table without contaminating the surroundings.

Hereinafter, typical embodiments of the apparatus of the present invention will be described mainly with reference to the accompanying drawings.
FIG. 1 is a perspective view of the softening device 10 of the present invention observed from the carrying surface side of the fin portion 2. FIG. 2 is a perspective view of the softening device 10 of the present invention shown in FIG. 1 observed from the carrying surface side of the flat surface 6 for smoothing operation.

  As shown in FIG. 1, the softening device 10 of the present invention includes a base 1, a plurality of fin portions 2 provided on at least one surface 1 </ b> A of the base 1, and a base 4 via a connecting portion 4. It includes at least a handle portion 3 connected to the base 1.

  The base 1 and the fin portion 2 are made of a heat conductive material, for example, copper and aluminum. The base 1 preferably includes heating means (not shown) inside. The said heating means can heat the temperature of the fin part 2 provided on the surface of the base 1 to the temperature which can soften a wax occlusion bank via the base 1 (for example, below wax melting temperature). In addition, the heating means is not particularly limited as long as it is a heating means capable of controlling the heating temperature, and examples thereof include an electric heater. Moreover, the base 1 can use a flame (direct fire) as a heating means, without providing a heating means in the inside. The size of the base 1 is limited as long as it can carry a row group of a plurality of fin portions 2 and a blade forming blade portion 5 to be described later and can provide a flat surface 6 for smoothing operation. For example, the length (that is, the length indicated by the symbol C in FIG. 2) is preferably 30 to 50 mm.

  The base 1 is usually a rectangular parallelepiped or cube having six faces, and one of the surfaces 1A is a fin portion carrying surface. The fin portion 2 erected on the fin portion carrying surface 1A of the base 1 needs to fulfill the function of softening the wax by directly contacting the wax occlusion bank. As for the fin part 2 provided in the softening apparatus 10 of this invention, the shape of the front-end | tip part which contacts a wax occlusion bank is a fan shape. The operation of softening the wax occlusion bank will be described in detail later, but it is possible to soften the wax occlusion bank by a fan-shaped arc-shaped portion, or by using acute angle portions at both ends of the fan shape.

  In general, the shape of the fin portion is not particularly limited. For example, as shown in FIG. 3, the shape including the fan-shaped tip portion 21 and the rectangular neck portion 22 (FIG. 3A), The shape composed of the fan-shaped tip 21 and the trapezoidal neck portions 23 and 24 [FIG. 3B or FIG. 3C], or the shape composed of only the fan-shaped tip 21 [FIG. 3D] Can be mentioned. The trapezoid neck 23 shown in FIG. 3B is a trapezoid neck having a trapezoid upper side shorter than the trapezoid lower side, while the trapezoid neck 24 shown in FIG. 3C has a trapezoid upper side longer than the trapezoid lower side. It is a trapezoid neck. The fan-shaped leading edge 21a is not only a smooth curve as shown in FIGS. 3A to 3C, but the leading edge 21b is 1 as shown in FIG. Or it can also be a shape provided with a plurality of fine cuts (grooves).

In the softening device of the present invention, it is also possible to soften the surface of the wax occlusion bank by the fan-shaped arc-shaped portion 21a of the fin portion. Further, by using the arc-shaped portion, the side wall region 8 on the front teeth portion palate side of the upper jaw or the lower jaw, which is difficult to be softened by the conventional spatula or the softening device shown in FIG. 5 of Patent Document 1 (see FIG. 4). Can be easily softened.
In addition, since the tip of the fin portion has a fan-shaped shape, when softening the wax occlusal embankment using the softening device of the present invention, a conventional softening device in which the tip of the fin portion has a rectangular shape (for example, a patent) Compared with the softening device shown in FIG. 5 described in Document 1, it can be softened from the upper surface of the wax bite to a predetermined depth with a smaller force. Furthermore, by softening the wax occlusion ridges at the sharp corners 21c and 21d at both ends of the fan-shaped fin portion, there is an advantage that softening in a narrow range is possible and a sufficient surgical field can be secured.

  In the softening device of the present invention, the width of the fan-shaped tip portion in the fin portion (that is, the length indicated by the symbol X in FIGS. 3A to 3D) is set to the width of the upper surface of the wax bite levee (that is, the figure). 4 is preferably set narrower than the length indicated by the symbol W in FIG. Therefore, in the softening device of the present invention, even if the wax melts on the upper surface of the wax occlusion bank, the molten wax can be prevented from flowing out to the side surface of the wax occlusion bank. It is possible to partially soften without reducing or losing the amount. In addition, the specific value of the width of the fan-shaped tip portion (that is, X in FIGS. 3A to 3D) is not particularly limited as long as a desired region can be softened. , Preferably 8 to 16 mm.

  The fin portion preferably has the neck portion (for example, a rectangular neck portion or a trapezoid neck portion) so that it is easy to observe the softening state of the wax occlusion bank. The width of the neck is not particularly limited as long as it is narrower than the width of the fan-shaped tip, and is preferably 4 to 8 mm. Here, the width of the neck portion means that when there is no change in the width (for example, the rectangular neck portion shown in FIG. 3A), the width [for example, the symbol R in the rectangular neck portion shown in FIG. When the width changes (for example, the trapezoidal neck shown in FIG. 3B or 3C), the maximum width [for example, FIG. 3B or FIG. Means the length indicated by the symbol R in the trapezoidal neck shown in (c)].

  When the fin portion is composed of a fan-shaped tip and a neck, the height of the fan-shaped tip (that is, the length indicated by the symbol S in FIGS. 3A to 3C) is the fan-shaped tip. In order to soften the wax occlusal embankment upper surface using the acute angle portions at both ends of the part, it is preferable to set the width of the wax occlusal embankment upper surface (that is, the length indicated by the symbol W in FIG. 4), The height of the neck portion (that is, the length indicated by the symbol T in FIGS. 3A to 3C) is preferably 1 to 9 mm. Further, the height of the fin portion including the height S of the fan-shaped tip and the height T of the neck [that is, the distance from the base surface to the fan-shaped tip; FIGS. 3 (a) to 3 (c) )] Is preferably 8 to 16 mm, for example. On the other hand, when the fin portion is composed only of the fan-shaped tip portion, the height of the fan-shaped tip portion (that is, the length indicated by the symbol Y in FIG. 3D) is the acute angle portion at both ends of the fan-shaped tip portion. In order to use and soften the upper surface of the wax occlusion bank, the width is set to be narrower than the width of the upper surface of the wax occlusion bank (that is, the length indicated by the symbol W in FIG. 4), and is preferably 4 to 16 mm.

  The thickness of the fin portion is not particularly limited as long as the fin portion can be pushed down from the upper surface of the wax occlusion bank to a predetermined depth to soften the wax, and various conditions such as the material of the fin portion and the necessity It can be determined as appropriate according to the strength of the fin portion to be applied. Preferably it is 0.1-1.5 mm, More preferably, it is 0.2-0.8 mm.

  The length of one row of the plurality of fin portions (that is, the length of the fin portion standing area), for example, a plurality of fin portions standing on the fin portion carrying surface 1A of the base 1 in the embodiment shown in FIG. The length from the first fin portion 2a to the last fin portion 2b (the length indicated by the symbol F in FIG. 1) is not particularly limited, and is preferably 15 to 45 mm, more preferably 20 to 40 mm, for example. It is. If the length of the fin portion standing area is less than 15 mm, the area that can be softened by a single contact becomes narrow, so the softening operation becomes complicated, and if it exceeds 45 mm, the softening operation of the curved section of the wax occlusion bank is performed. Since it becomes complicated, it is not preferable.

  The mutual spacing of the fin portions (for example, the length indicated by the symbol f in FIG. 1) that stands parallel to each other on the fin portion carrying surface of the base is determined by bringing the parallel fin portions into contact with the wax occlusion dam. When the wax is melted, when the softening device of the present invention is released from the melted wax occlusion bank, the interval is set such that the molten wax is sucked between adjacent fin portions by the surface tension and is not removed from the wax occlusion bank. It is preferable. Specifically, the interval between adjacent fin portions (distance between surfaces of adjacent fin portions) is preferably 1.5 to 4.5 mm, more preferably 2 to 4 mm.

  The number of fin portions provided on the fin portion carrying surface of the base is not particularly limited. For example, the length for providing the fin portion (that is, the fin portion standing region length; F in FIG. 1), It is determined by the relationship with the interval between the fin portions. Specifically, the number is preferably 4 to 15.

  Each of the plurality of fin portions provided on the fin portion carrying surface of the base can use only fin portions having the same shape, or two or more types of fin portions (however, each The fins are assumed to have the same height), but the wax occlusal embankment can be uniformly softened so that only fins having the same shape are used. preferable.

  In addition, for example, as shown in FIG. 1, an aspect in which a plurality of fin portions are arranged on the fin portion carrying surface of the base is erected in a direction perpendicular to the length direction of the fin portion carrying surface 1 </ b> A of the base 1. The fins thus formed are preferably arranged in parallel to each other and in a line in the length direction of the fin portion carrying surface 1A of the base 1. The intervals between the fin portions can be all constant, or two or more different intervals can be combined, but the wax occlusal embankment can be uniformly softened. , It is preferable that they are all at regular intervals.

  As shown in FIGS. 1 and 2, the handle portion 3 in the softening device 10 of the present invention is a portion that is held by a person who performs the softening operation of the wax occlusal dyke, and has a shape suitable for the operation. preferable. As will be described later, the specific softening operation is performed by using one of the sharp corners 21c and 21d at the ends of the fan-shaped tips of the fins 2 arranged on the fin support surface 1A of the base 1 on the upper surface of the wax occlusion bank. This is a manual operation that presses against a predetermined region 72 and the like, and further pushes down to a predetermined depth from the wax occlusal surface to soften it. Alternatively, it is a manual operation for softening the wax by pressing the arc-shaped portion 21 at the fan-shaped tip of the fin portion 2 against a predetermined region on the upper surface of the wax occlusion bank and further pressing down from the upper surface of the wax occlusion bank to a predetermined depth. . Accordingly, examples of the shape of the handle portion 3 include a columnar shape (for example, a prismatic shape or a cylindrical shape) that can handle the entire softening device 10 with one hand as shown in FIGS. 1 and 2. .

  As shown in FIGS. 1 and 2, the handle portion 3 may be provided with a power cord 31 for supplying energy to the heating means provided in the base 1, or the handle portion 3 An energy supply means (for example, a battery or a battery) to the heating means may be provided inside.

  As shown in FIGS. 1 and 2, the connecting portion 4 in the softening device 10 of the present invention is a portion that connects the base 1 and the handle portion 3. Accordingly, the connecting portion 4 needs to be formed of a material that does not excessively heat the handle portion 3 due to the heat of the base 1 heated to the softening temperature or melting temperature of the wax. For example, the heat conductivity is low. A material (more preferably a heat insulating material), for example, a heat resistant resin (eg, silicone, Teflon (registered trademark)), a softening resistant resin (eg, a resin that softens at a temperature higher than the softening temperature of wax), or aluminum It is preferable to form from an alloy.

  As shown in FIG. 1 and FIG. 2, the softening device 10 of the present invention is for smoothing operation of at least one surface 1B of the base 1 made of a conductive material, if desired, in addition to the fin portion carrying surface 1A. For example, the surface can be a flat surface 6 for a smoothing operation whose surface is flat. The flat surface 6 for smoothing operation can be used to smooth the surface of the wax occlusion bank while softening or melting it. Examples of such smoothing operations include, for example, an operation of returning wax that has flowed from the upper surface of the wax occlusion bank to the upper surface of the wax occlusion bank, an operation of smoothing the surface of the wax occlusion bank immediately after the formation of the wax occlusion bank, or a wax occlusion The surface smoothing operation in the height adjustment process of a bank can be mentioned.

  Instead of the flat surface 6 for the smoothing operation shown in FIGS. 1 and 2, the base 1 of the softening device of the present invention is curved in the same shape as the cylindrical side wall surface as shown in FIG. 6 (partial sectional view). It can also have a surface 6A. The curved surface 6A is preferably provided on a surface different from the fin portion carrying surface 1A carrying the fin portion 2 and the groove forming blade portion 5, particularly on the opposite surface as shown in FIG. It can be used for softening the curved portion of the occlusal levee and for smoothing the wax occlusal levee surface.

  As shown in FIG. 1 and FIG. 2, the softening device 10 of the present invention is provided with a base plate, if desired, in addition to or in addition to the flat surface 6 for smoothing operation, in addition to the fin portion carrying surface 1A. A groove-forming blade portion 5 made of a heat conductive material (for example, copper and aluminum) can be further provided on at least one surface 1C of one. The groove-forming blade portion 5 can be used for softening a portion that is insufficient by softening at the fin portion when the wax occlusal surface is softened at the fin portion. It can also be used to form a groove for guiding the softened or melted wax on the upper surface of the wax bite. Specifically, when softening at the fin portion, the blade is applied to a place where the softening is insufficient with only the groove formed between the fin portion and the fin portion. At this time, the occlusal bank predetermined region can be suitably softened by applying the groove forming blade portion 5 to the groove made of the fin portion at a right angle to form a lattice-like groove.

Actually, for example, as shown in FIG. 4A, in the softening process of the wax occlusal dam upper surface 7A, the acute angle portion 21c at one end of the fan-shaped tip of the fin portion 2 is pressed against a predetermined region 72 on the upper surface of the wax occlusal levee. Furthermore, it is pushed down from the wax occlusion surface to a predetermined depth and softened to form parallel grooves by the fin portions. Next, without changing the handle part as it is, the acute angle part 21d on the opposite side of the fan-shaped tip of the fin part 2 is pressed against the area 73 on the opposite side of the upper surface of the wax occlusion dam and softened to form a similar parallel groove. Next, by applying the blade portion 5 at right angles to the parallel grooves formed by the fin portions, lattice-like grooves can be formed, and the predetermined regions 72 and 73 can be sufficiently softened.
Furthermore, as shown in FIG. 4B, in the step of softening the wax occlusion dam upper surface 7A, before bringing the fin portion 2 into contact with the upper surface 7A of the wax occlusion dam 7, A linear groove, that is, a wax guiding groove 71 can be formed by using the groove forming blade portion 5 along the horseshoe shape formed by the upper surface 7A of the wax occlusion bank. The wax guiding groove 71 can be adjusted to a desired width and depth by adjusting the position and time at which the groove forming blade part 5 is brought into contact with the wax biting ridge upper surface 7A. The width and depth of the wax guiding groove 71 is such that the softened or melted wax is guided so that the softened or melted wax does not flow down the wax biting dam 7 from the wax biting ridge upper surface 7A. There is no particular limitation as long as it can be stored inside.

  Further, the length of the groove forming blade portion 5 (that is, the length indicated by the symbol B in FIG. 2) is not particularly limited as long as a groove can be formed along the horseshoe shape. The width (that is, the length indicated by the symbol A in FIG. 2) is preferably 2 to 8 mm. The length (B in FIG. 2) of the groove forming blade portion 5 is the length of the fin portion standing area of the base 1 (F in FIG. 1; standing on the fin portion carrying surface 1A) as shown in FIG. It is preferable that the length of the plurality of fin portions 2 provided is substantially equal to the length from the leading fin portion 2a to the final fin portion 2b).

When performing the softening operation of the wax occlusal embankment using the wax occlusal embankment softening device 10 according to the present invention of the embodiment shown in FIGS. 1 and 2, for example, first, the base 1 is heated to the temperature of the fin portion. To a wax softening temperature or a wax melting temperature. Subsequently, the softening operator grasps the handle portion 3 and, as shown in FIG. 4A, presses the acute angle portion 21c at one end of the fan-shaped tip portion of the fin portion 2 against a predetermined region 72 on the upper surface of the wax occlusion dam to soften it. And parallel grooves are formed by the fin portions. Next, without changing the handle part as it is, the acute angle part 21d on the opposite side of the fan-shaped tip of the fin part 2 is pressed against the area 73 on the opposite side of the upper surface of the wax occlusion dam to soften it, thereby forming a similar parallel groove. Then, the upper surface 7A of the wax occlusion bank 7 is softened sequentially using the acute angle portions 21c and 21d at both ends of the fan-shaped tip. Next, a grid-like groove can be formed on the wax occlusal surface by applying the parallel groove formed by the fin groove on the wax occlusal surface and the groove forming blade portion 5 at a right angle. By forming the lattice-like grooves in this way, sufficient softening can be obtained over the entire wax occlusal surface even when the softening operation of only the parallel grooves of the fin portion is insufficient.
In addition, when the upper surface 7A of the prepared wax occlusal embankment 7 is not a smooth surface, it can be smoothed using the flat surface of the flat surface 6 for smoothing operation before being softened by the fin portion. . In addition, in the softening process, when it is necessary to form a smooth surface, it can be smoothed using the flat surface of the flat surface 6 for the smoothing operation.

As another method for the softening operation of the wax occlusal surface, the softening operator holds the handle portion 3 and, as shown in FIG. 4B, the groove forming blade portion 5 is provided at the center of the upper surface 7A of the wax occlusal levee 7. A wax guiding groove 71 is formed in order. Next, as shown by a broken line in FIG. 4B, the upper surface 7A of the wax occlusion ridge 7 is softened one after another by pressing the row group 20 of the fin portions 2 from above the formed wax guiding groove 71. Thus, softening of the entire wax occlusal surface can be easily obtained.
Of course, it is also possible to partially soften the wax occlusal surface by using the fin portion and the groove forming blade.

  According to the wax occlusal embankment softening device 10 according to the present invention, it is possible to easily perform a softening process on a part of the upper surface 7A of the wax occlusal embankment 7, for example, a softening process with the row group 20 of the fin portions 2 as a unit. Therefore, it is advantageous for fine adjustment in determination adjustment of the occlusal position.

The softening device of the present invention can be used to soften the wax occlusal levee in the course of manufacturing a plate denture (so-called partial denture and total denture).
The softening device of the present invention is suitable not only for the purpose of softening the entire upper surface of the wax bite bank, but also for the use of partially softening the upper surface of the wax bite bank.
Further, since the softening device of the present invention is small and light, it can be quickly operated by the patient on the dental examination table.
Furthermore, the softening device of the present invention can properly grasp the softening state of the wax occlusal levee which is in contact with the softening device.
