Abstract

Disclosed are a prosthesis crown of gums and a prosthesis crown kit of gums, with which a surgical method is provided so that, even using one-piece one-time operation, a pretty appearance can be achieved with no gap formed between the prosthesis crown and the gums. The prosthesis crown of gums 1 is inserted with an abutment 13 of an one-piece type implant 10 into an insertion hole 4, and thus the shape of a gums hole G1 can be constantly maintained by burying a part of outer peripheral surface into the gums hole G1 without making a recession of gingival papilla and/or interdental papilla, so as to be supported by outer peripheral surface of a cap body 2. Thus, a prosthesis crown can be formed after being molded, and the prosthesis crown is buried under the gums hole G1 around the abutment 13 so that there is no gap formed between the gums G. Therefore, even using one-piece one-time operation, the surgical method can achieve a pretty appearance with no gap formed between the prosthesis crown and the gums. In addition, for continuously increasing pretty appearance, in comparison with the prior two-piece type implant, the surgical operation using the simple one-piece type implant is easy and convenient so as to greatly reduce the burden of a patient in physical body, consciousness and expense.

Description

Tooth-shaped crown and dentate shaped crown group

The invention relates to a tooth-shaped crown and a tooth-shaped crown group.

In recent years, dental implants have been known to have a single-piece implant integrally formed with a head portion (hereinafter referred to as an abutment) in which a false crown is assembled, and a screw portion embedded in a toothed groove bone (for example, reference non- Patent Document 1). In fact, an example of a surgical method using the one-piece implant, as shown in Fig. 15A, has a toothed groove bone (for example, a tibia) B in the tooth G of the tooth extraction site or the missing tooth space. The buried hole B1 is formed. Next, as shown in FIG. 15B, after the screw portion 11 of the one-piece implant 10 is implanted into the embedding hole B1, the ligament G is sewn in a state in which the abutment 13 is exposed to the flesh G, whereby The single piece implant 10 is implanted into the toothed groove B. Thereafter, during a quiet interval, the single-piece implant implanted into the toothed bone B is combined with the toothed groove B. After the quiet period, the periphery of the abutment 13 of the single-piece implant is taken, and the abutment 13 of the single-piece implant and the tooth-shaped false crown of the periphery thereof are prepared, as shown in FIG. 15C. The abutment 13 of the one-piece implant and the tooth-shaped false crown 208 of the periphery thereof are assembled to the abutment 13.

Moreover, the surgical methods using other dental implants include the use of an abutment assembled with a false crown, and the snail of the tooth groove B implanted in the extraction site. The silk is a two-piece implant of different individuals. First, only the screw portion is implanted into the tooth groove B and the tooth G is sutured. After the quiet period, the tooth G is cut again to expose the tip of the screw and assembled. The abutment to the tip of the screw is called a two-piece two-step operation.

In contrast, in the above-described surgical method using the one-piece implant 10, for example, the cut tooth G can be used, so that the abutment 13 is exposed from the tooth G to implant the single-piece implant 10 to the tooth groove. Bone B, after that, the incision of the G. G. is called the one-piece one-step surgical method. Compared with the surgical method called the two-piece two-step method, the number of cuts of the G is reduced, which can shorten the healing period. . Moreover, the one-piece implant 10 can cut the tooth G only once, so that the mental burden of the operator and the patient can be reduced, and the structure is simple and the number of parts is compared with the two-piece implant. Less, so, can reduce costs.

(1) Outline of the tooth-shaped crown of the present invention, and the composition of the tooth-shaped crown of the present invention

In Fig. 1A and Fig. 1B, 1 shows the tooth-shaped crown of the present invention, and the configuration of the tooth-shaped crown 1 can be assembled in a single-piece implant 10, a single-piece implant. The body 10 is formed in a tooth hole between the two teeth T1 and T2 (formed in an implant insertion hole such as a tooth extraction hole or an edentulous hole or a missing tooth, hereinafter referred to as a "tooth hole") G1. Further, in the tooth hole G1 between the two teeth T1, T2, an embedding hole (not shown) is formed in the tooth groove bone B by the drill bit, and the single-piece type implant 10 is implanted in the embedding hole. The screw portion 11 is thereby configured such that the abutment 13 at the tip end of the screw portion 11 can be exposed. Therefore, the abutment 13 is constituted by the column portion 12a and the inclined tip end portion 12b, and the column portion 12a is formed in a columnar shape (cylindrical or polygonal columnar shape having the same diameter as that of the screw portion 11, so that the diameter of the screw portion 11 is slightly In other columnar shapes such as cylindrical or the like, the inclined tip end portion 12b is integrally formed at the tip end of the column portion 12a, and the closer to the tip end, the cross section becomes a non-circular shape, as shown in Fig. 1B, for the portion of the column portion 12a. And the inclined tip portion 12b, the tooth-shaped crown 1 can be assembled.

The tooth-shaped crown 1 of the present invention is assembled in the tooth groove bone B shortly after being implanted in the one-piece implant 10, and is configured to be partially buried in the single-piece implant 10 The tooth hole G1 under the tooth flanks shortly after the tooth groove B, in this state, passes through the quiet period, thereby making it possible to match the teeth around the tooth hole G1 to the tooth-shaped crown The outer peripheral surface of 1. In this case, the dentate shaped crown 1 is formed of a hard member such as a resin or a zirconia or ceramic having good biocompatibility, thereby being assembled even into a one-piece type implant. The bite after 10 is not damaged by the applied external force, and the shape around the tooth hole G1 can be maintained. Actually, this tooth-shaped crown 1 has a cylindrical crown body 2 in which the insertion hole 4 is formed, and can be inserted into the abutment 13 of the one-piece implant 10 to the insertion hole 4.

The crown body 2 is selected with a root portion 2c so as to be insertable into the tooth hole G1 between the teeth T1, T2, and at the same time, when the root portion 2c is inserted into the tooth hole G1, the diameter of the tip end face 2a is selected so that the tip end portion The outer peripheral surface of 2b is in contact with the teeth T1, T2 so that it is difficult to form a gap between the teeth T1 and T2. Further, in the crown body 2, the opening 4a on the side of the insertion hole 4 is formed in the tip end surface 2a, and the opening 4b on the other side of the insertion hole 4 is formed on the root surface 2d facing the tip end surface 2a, and the abutment 13 can be self-contained The opening 4b of the root surface 2d is inserted into the opening 4a of the tip end surface 2a.

Further, the crown body 2 is selected such that its height is lower than the height of the teeth T1 and T2, and when assembled in the one-piece type implant 10, it is formed in a state in which the teeth T1 and T2 are not protruded from the tip end. In the field of 2a, a dental patch material such as a polymer resin material can be constructed. Thereby, the crown body 2 is formed with a dental patch material on the tip end surface 2a, and has a shape integrated with the dental patch material, whereby a denture can be formed between the teeth T1 and T2. Further, the dental patch material is formed on the tip end surface 2a of the crown body 2 or its periphery by, for example, a pen, and the like, and then the denture is formed by hardening. In the case of the present embodiment, the outer peripheral surface of the root portion 2c of the crown main body 2 has a smooth shape without irregularities. Therefore, when the dental patch material is constructed, the appearance is similar to that of the other teeth T1 and T2. tooth.

In fact, in the case of this embodiment, the crown body 2 is made up of a circle The cylindrical tip end portion 2b and the conical seat-shaped root portion 2c are formed, the tip end portion 2b is fitted with the teeth T1, the width between T2 is selected to be the diameter of the tip end surface 2a, and the root portion 2c is selected such that the root surface 2d has a diameter larger than the tip end surface. The diameter of 2a is also small, and has an inclined surface from the tip end portion 2b toward the root surface 2d, and an insertion hole 4 is bored in the axial center of the tip end portion 2b and the root portion 2c. The crown body 2 is gradually reduced in diameter from the tip end portion 2b toward the root surface 2d of the root portion 2c, and is assembled between the teeth T1 and T2, between the teeth T1 and the root portion 2c, or the tooth T2. Between the root portion 2c and the root portion 2c, an ideal triangular tooth nipple can be formed.

The insertion hole 4 is fitted with the contour shape of the abutment 13 used for the patient, and is formed with an internal space. When the single-piece type implant 10 is inserted, the inner wall abuts against the abutment 13, and the positioning of the abutment 13 can be positioned. The height position of the crown 1 . Actually, inside the insertion hole 4, the insertion inner wall portion 4d having a shape corresponding to the outline shape of the cylindrical portion 12a in the abutment is formed on the side of the root surface 2d, and at the same time, the shape corresponds to the contour shape of the inclined tip portion 12b in the abutment 13. The positioning portion 4c is formed on the tip end surface 2a side. The insertion hole 4 is selected by the ratio of the insertion of the inner wall portion 4d and the positioning portion 4c, and the degree of insertion of the crown body 2 with respect to the abutment 13 is selected so that the degree of embedding the crown body 2 into the tooth hole G1 can be adjusted. .

In addition to the above configuration, the crown body 2 is formed with a rectangular parallelepiped projection 3 extending outward from the tip end surface 2a. The protrusion 3 is selected after assembling the dentate shaped crown 1 to the one-piece implant, and the height thereof is not protruded from the height of the adjacent teeth T1, T2, so that even after assembling the dentate shaped crown 1 In the state after the one-piece implant 10, when engaged, it does not collide with the opposing teeth. The protrusion 3 can be held by a finger or a forceps, whereby the insertion hole 4 of the tooth-shaped crown 1 can be easily inserted into the bridge in the limited space in the oral cavity. Taiwan 13.

Here, as shown in FIG. 1B, even if the tooth T1 adjacent to one side of the tooth-shaped crown 1 is regarded as a natural tooth, the tooth T2 on the other side adjacent to the tooth-shaped crown 1 is regarded as In the case of a false crown, the width W1 between the single-piece implant 10 and the tooth (natural tooth) T1 in the tooth and the width between the single-piece implant 10 and the tooth (false crown) T2 in the tooth are considered. W2, again, considers the apex of the toothed groove B between the one-piece implant 10 and the tooth T1 (the top of the tooth groove), the height H1 to the apex of the tooth, and the self-single type implant 10 The apex of the tooth groove B (the top of the tooth groove) between the tooth T2 and the height H2 of the apex of the tooth can be selected to be the width W1 of the tooth-shaped crown 1 assembled in the one-piece implant 10. And the degree of insertion of the tooth-shaped crown 1 for the abutment 13.

Thereby, the tooth-shaped crown 1 is formed into a denture in a state of being assembled to the one-piece type implant 10, and is removed from the one-piece implant 10 after a quiet period, whereby the tooth hole G1 The surrounding tooth line becomes a scallop form (the shell-like shape of the scallops), or the ideal shape of the tooth line that is blended with the surrounding, which can be a very beautiful tooth line.

Further, such a tooth-shaped crown 1 can be produced by, for example, injection molding, baking, cutting, or the like. 2A, 2B, and 2C are actually a tooth-shaped crown 1 made of a hard member such as zirconia or ceramic having good resin or bio-affinity, which has a crown body 2 The tip end surface 2a is integrally formed with a thin-walled cube-shaped projection 3. In this case, the tooth-shaped crown 1 is formed in the opening portion 4a of the insertion hole 4 on the tip end surface 2a side, and the positioning portion 4c in the insertion hole 4 is fitted to the contour shape of the abutment 13 to form a quadrangle (2B). FIG. 4 shows the opening 4b of the insertion hole 4 on the root surface 2d side, and the insertion hole 4 The insertion inner wall portion 4d is formed in a circular shape (second FIG. 2C), and the opening portion 4a of the insertion hole 4 on the tip end surface 2a side and the positioning portion 4c abut against the inclined tip end portion 12b of the abutment 13 (Fig. 1A). It can be positioned by the abutment 13.

Further, as shown in Fig. 2C, the corner portion between the outer peripheral surface of the base portion 2c and the root surface 2d of the crown body 2 is smoothly curved, and when the abutment 13 is inserted into the insertion hole 4, the abutment 13 is not damaged. The surrounding toothed ground can be buried in the tooth hole G1.

(2) An example of a surgical procedure performed by a single-piece method using a tooth-shaped crown

Next, the surgical procedure performed by the one-piece one-shot method using the tooth-shaped crown 1 will be described below. Here, the third figure shows that the operator enlarges the upper inner lip of the upper lip Upl of the patient with the finger Fin, and extracts the other incisor between the middle incisor T1a on one side and the side incision T2b on the other side (not shown). The state in which the single-piece implant 10 is implanted into the dental hole G1 (corresponding to the above-mentioned tooth hole G1, and all of them are regarded as the tooth extraction hole G1, which will be described below). Further, in Fig. 3, T2a is the side incisor of the upper jaw, T3a, T3b is the canine of the upper jaw, T4a, T4b is the first small molar of the upper jaw, and T5b is the second small molar of the upper jaw.

Moreover, although it is suitable for implanting the single-piece implant 10 immediately after the tooth extraction, it is also suitable for implanting a single-piece implant after a quiet period after tooth extraction. When the tooth is extracted, it is buried in the law. In the case of both of the above, the tooth-shaped crown 1 of the present invention is used shortly after the implantation of the one-piece implant. In this case, in the dental extraction hole G1 formed by the extraction, the single-piece implant 10 is implanted, and the abutment 13 is exposed from the dental extraction hole G1, and a hollow region can be formed around the abutment 13.

Shortly after the implantation of the single-piece implant 10, the tooth-shaped crown 1 is prepared, as shown in Fig. 4A, by the forceps 200 sandwiching the crown body 2 formed on the tooth-shaped crown 1 After the crown portion 1 is held by the protruding portion 3, as shown in Fig. 4B, the opening portion 4b (Fig. 1A) from the root surface 2d side of the crown body 2 is inserted into the abutment 13 into the insertion hole 4, such as As shown in Fig. 4C, the tooth-shaped crown 1 is inserted along the abutment 13 into the extraction hole G1.

At this time, the operator foresees the size of the extraction hole G1, or the state of the tooth around the tooth extraction G1, the shape of the scallop which is finally formed (the shape of the shell-shaped tooth of the scallop), or the ideal tooth line that is blended with the surroundings. In the form of the tooth-shaped crown 1 of different sizes, it is suitable to select the optimal size of the tooth-shaped crown 1 and assemble the selected tooth-shaped crown 1 to the abutment 13 in the tooth hole G1. .

Thereby, as shown in FIG. 4C, the tooth-shaped crown 1 is inserted into the extraction hole G1, whereby the hollow region in the extraction hole G1 is continuously ensured, and the tooth extraction is supported along the outer circumferential surface of the crown body 2 The dentate around the hole G1 maintains the dentate line in an optimal state, for example, a spur-like ideal interdental nipple. Next, as shown in FIG. 5A, the distal end surface 2a (FIG. 1A) of the tooth-shaped crown 1 fitted into the abutment G1 is fitted to the abutment 13 and the outer peripheral surface around the tip end surface 2a. The dental patch material 202 such as a polymeric resin material is constructed by the pen 201.

Further, the dental patch material 202 is hardened, and as shown in FIG. 5B, the dental prosthesis FT in which the crown body 2 of the tooth-shaped crown 1 is integrated with the dental patch material 202 is formed at the tooth extraction site. Furthermore, when constructing the dental patch material 202 to the dentate shaped crown 1 to form the denture FT, the adjacent teeth (in Therefore, the distance between the middle cutting tooth T1a on one side and the side cutting tooth T2b) on the other side does not coincide with the width of the crown body 2, and it is assumed that the width of the crown body 2 is small even when compared with the distance between adjacent teeth. Forming a gap, by supplementing the constructed dental patch material 202, it is also possible to form a denture FT that is juxtaposed with adjacent teeth without gaps.

In this way, the tooth-shaped crown 1 assembled shortly after the single-piece implant 10 is implanted, the single-piece implant 10 is combined with the tooth groove B until the teeth around the tooth G1 are extracted. The state of the meat is improved to maintain the state of being assembled on the one-piece implant 10. Next, after the one-piece implant 10 is combined with the quiet period of the toothed bone B, the tooth-shaped crown 1 is removed from the one-piece implant 10, and the dental prosthesis FT is removed.

FIGS. 6A, 6B, and 7 show the state of the teeth shortly after the tooth-shaped crown 1 is removed from the one-piece implant 10 after the quiet period. As shown in Fig. 6A, Fig. 6B, and Fig. 7, the dentine G around the extraction hole G1 of the tooth-shaped crown 1 is assembled, and the dentate line GL is in the form of a scallop (the shell-shaped scallop of the scallop) In the line form), the periphery of the extraction hole G1 can be the same as the tooth G around the other teeth T1a and T2b. Further, a relatively deep extraction hole G1 can be left around the abutment 13.

Next, the periphery of the abutment 13 or the bridge 13 is taken out from the periphery of the tooth which is exposed from the dental hole G1, and the model 205 shown in Fig. 8 is formed. Further, after the ejector of the extraction hole G1 is taken, the denture FT formed by the tooth-shaped crown 1 is assembled in advance on the abutment 13 until the crown is made. Further, the model 205 shown in Fig. 8 is formed by the abutment reproducing unit 207 which faithfully reproduces the periphery of the abutment 13 in the extraction hole G1 of the patient, or faithfully reproduces the teeth around the extraction hole. The meat-shaped tooth reproduction unit 206 can produce a false crown 208 suitable for the shape of the abutment 13 and the extraction hole G1.

Fig. 9 shows a false crown 208 which is produced by the abutment reproducing unit 207 and the flesh reproducing unit 206 of the model 205. As shown in Fig. 9, the false crown 208 is formed with the tooth portion 208a having the same shape as that of the natural tooth, and the buried portion 208b buried in the extraction hole G1 can be formed. Further, in the dummy crown 208, an assembly hole 209 in which the abutment 13 is inserted into the end portion of the buried portion 208b may be formed.

When the false crown 208 is fabricated, the prosthesis FT assembled on the abutment 13 is again removed, and as shown in Fig. 10A, the false crown 208 is assembled to the abutment 13. At this time, the assembly hole 209 of the abutment 13 to the false crown 208 is inserted, whereby the buried portion 208b of the false crown 208 can be buried into the extraction hole G1, and as shown in FIG. 10B, along the buried portion 208b and the tooth portion. At the boundary of 208a, the dentate line GL is positioned. In this way, the dentine line GL is in the form of a scallop, or an ideal dentate line shape which is harmonized with the shape of the surrounding tooth, and a beautifully shaped dentate line GL can be formed.

Moreover, although the one-piece type implant 10 made of titanium is used this time, even if it is a thin biochemical type G, the bridge 13 does not pass, and the tooth G like a natural tooth can be formed. This is because the tooth-shaped crown 1 can be buried in the tooth hole G1 (the tooth hole G1) around the abutment 13, and sufficient tooth is left around the abutment 13, and the denture is arranged in the tooth hole G1 around the abutment 13 Crown 208, therefore, by the white color of the surface of the false crown 208, the dark color (titanium color) of the abutment 13 can be prevented from passing through the tooth G.

(3) Function and effect

In the above configuration, in the tooth-shaped crown 1 of the present invention, the abutment 13 of the false crown 208 is assembled, and the screw portion 11 embedded in the tooth groove B is attached. The one-piece type implant 10 which is integrally formed is provided such that a cylindrical crown body 2 formed with an insertion hole 4 into which the abutment 13 can be inserted is provided. Further, in the tooth-shaped crown 1, the abutment 13 of the one-piece type implant 10 implanted in the tooth groove bone B is inserted into the insertion hole 4, and the partial surface of the outer peripheral surface of the crown body 2 is buried. In the meat hole G1, the state of the tooth hole G1 is continuously maintained so that the outer peripheral surface of the crown body 2 is supported without retracting the tooth nipple and/or the interdental nipple (that is, the tooth).

In the dentate shaped crown 1, the one-piece implant 10 is maintained in an assembled state for the abutment 13 until after a quiet period of engagement with the toothed bone B, whereby a crown body can be formed along the crown The outer peripheral surface of 2, the shape of the dentate G. Thereafter, the scalloped crown 1 is detached from the abutment 13 to form a false crown 208 which is formed in the tooth hole G1 formed around the abutment 13 and which is fitted around the tooth hole G1. The denture crown 208 thus produced can form a buried portion 208b that is buried in the perforation hole G1 around the abutment 13. In this way, in the tooth-shaped crown 1, the portion is buried in the tooth hole G1, and a gap is formed between the tooth and the tooth G, so that the false crown 208 which can be assembled on the abutment 13 can be formed. Can improve the aesthetics. Further, in the tooth-shaped crown 1 of the present invention, even if the surgical method by the one-piece method is used, no gap is formed between the crown 208 and the tooth G, and the appearance can be improved.

Further, in this tooth-shaped crown 1, after the one-piece implant 10 is implanted, shortly after the planting, the abutment 13 is inserted into the insertion hole 4 to bury the crown body 2 to the tooth hole G1. In this case, the denture FT can be formed, so that it is not necessary to suture the surrounding tooth G in a large amount shortly after the single-piece implant is implanted, or, in this case, the tooth G is not sewn at all. The crown body 2 can be used to form the denture FT, thereby reducing the burden on the operator or the patient.

Further, in the tooth-shaped crown 1 of the present invention, after being inserted into the abutment 13, the positioning portion 4c for positioning the crown body 2 with respect to the abutment 13 is formed in the insertion hole 4, so that the positioning portion 4c is The degree of burying of the crown body 2 in the tooth hole G1 is adjusted. Thereby, in the tooth-shaped crown 1, the height of the teeth T1, T2 corresponding to the adjacent tooth extraction portion or the missing tooth portion, or the state of the tooth hole G1 of the abutment 13 and the teeth around the tooth hole G1 are exposed. The state of the meat nipple and/or the state of the interdental nipple can be positioned to the optimal position of the outer peripheral surface of the crown body 2 so as to be in the form of a scallop or a shape of the dentate line which is harmonized with the shape of the surrounding tooth.

Further, in the tooth-shaped crown 1, when the abutment 13 is inserted into the insertion hole 4, the protrusion 3 for holding the crown body 2 by the operator can be provided even in the restricted mouth. It is easy to insert the insertion hole 4 into the abutment 13 exposed in the tooth hole G1.
