Definitions
- the present invention relates to a retainer wire for use in a dentition retention device, which is composed of a transparent synthetic resin labial line and a metal wire. More specifically, it is a retainer wire that can connect the labial line and the metal wire and can be separated, and maintains the desired toothpaste 1J by pinching the corrected tooth between the base and the holding means.
- the present invention relates to a retainer wire used in a dentition retention device.
- the retainer wire 50 disclosed in US Pat. No. 6,332,774 has an arcuate shape that abuts against a portion corresponding to the front tooth in the dentition.
- the lip side line 51 made of a transparent synthetic resin exhibiting the above, and a metal wire 52 fixed to the lip side line 51 and a force.
- the metal wire 52 includes a norep 52a and a support 52b.
- the fixing of the metal wire 52 to the labial line 51 is achieved in a state where the end of the metal wire 52 is submerged in the lip side line 51. It has the advantage of a significant improvement (approximately 9. Okg). Further, when producing the retainer, there is an advantage that the process of physically joining the two parts of the plastic part (labial line 51) of the front tooth part and the metal wire 52 of the loop 52a and the support part 52b becomes unnecessary. is there. Further, the conventional retainer wire shown in FIG. 5 has an advantage that the labial line 51 is made of a transparent synthetic resin, so that it is not noticeable even if the retainer wire is attached.
- An object of the present invention is to provide a retainer wire for use in a dentition holding device that can solve the problem of force and the conventional holding device and can easily replace only the labial line. Disclosure of
- the retainer wire according to the first aspect of the present invention includes a labial line formed in an arc shape so as to be in contact with the dentition on the anterior tooth side,
- the labial line is made of a synthetic resin having transparency and predetermined mechanical strength, and the metal wire is screwed to the screw part fixed to both ends of the labial line and the screw part. Connected via another screw
- a force S can be used in which the screw portion is a male screw and the other screw portion is a female screw engraved in a socket.
- the inner side of the socket has a substantially cylindrical shape, and a hook for locking the metal wire is provided at one end, and is locked to the hook at one end of the metal wire. It is preferable that a bulge is provided.
- a dentition retention device is a retainer wire having both ends fixed to a base portion and looped around so as to surround a plurality of teeth including orthodontic treated teeth.
- a dentition retention device comprising:
- the labial line is made of a synthetic resin having transparency and predetermined mechanical strength, and the metal wire is screwed to the screw part fixed to both ends of the labial line and the screw part. Connected via another screw
- a dentition retention device A dentition retention device.
- FIG. 1 is a perspective view showing a state in which a retainer wire according to an embodiment of the present invention is attached to a dentition of a dental model.
- FIG. 2 (a) is a perspective view showing a labial line of the retainer wire of FIG. 1, (b) is a perspective view showing a metal wire of the retainer wire of FIG. 1, and (c) is a perspective view of FIG. It is a partially broken perspective view which shows the socket for connecting the lip side line of a retainer wire, and metal wires.
- FIG. 3 is an exploded perspective view of the retainer wire of FIG.
- FIG. 4 is a perspective view showing a dentition holding device of the present invention showing a state in which the retainer wire of FIG. 1 is attached to a base portion.
- FIG. 5 is a perspective view showing a state in which a conventional retainer wire is attached to a dentition of a dental model.
- FIG. 6 is a perspective view showing a labial line of the retainer wire in FIG. 5.
- the retainer wire 1 includes an arcuate labial line 11 that abuts against a portion corresponding to the front tooth in the dentition, and a metal that extends from both ends of the labial line. It consists of 12 wires made of steel. [0014]
- the labial line 11 is made of a synthetic resin having transparency and a predetermined mechanical strength.
- the metal wire 12 includes a screw portion S1 fixed to both ends of the labial line 11, and the screw portion S.
- the fixing of the screw part S 1 to the labial line 11 is achieved in a state where a part of the screw part S 1 is submerged in the labial line 11.
- screw portion S1 is a male screw
- another screw portion S2 Is a female screw engraved in the socket 13.
- the screw portion S1 can be a female screw engraved in a socket embedded at both ends of the labial line 11, and another screw portion S2 can be a male screw that is screwed with the female screw.
- Forms are also included in the present invention.
- the socket has a substantially cylindrical shape, and a flange 13f for locking the metal wire 12 is provided at the end. Further, as shown in FIG. 2 (b), one end of the metal wire 12 is provided with a bulging portion 12a that is locked to the flange 13f.
- the retainer wire 1 of the present invention configured as described above is also provided with a high pull-out strength at the joining portion (9. similar to the retainer wire disclosed in the aforementioned US Pat. No. 6,332,774). Okg) is obtained, and the variation in bonding strength due to the bonding technique of the manufacturer is eliminated, and uniform pullout strength is obtained.
- the retainer wire of the present invention also undergoes thermal shrinkage due to heat shrinkage of the plastic. Therefore, when creating the retainer wire, as shown in FIG. When set and heated above a specified temperature (regardless of wet or dry heat), the plastic part of the retainer wire 1 (labial line 11) undergoes heat shrinkage, making it easy on the surface of the dentition model Will be along.
- thermoplastic resin retainer wire made of a thermoplastic resin according to the present invention is placed lightly along the tooth model, and a temperature higher than the shrinkage temperature of each resin is set. By applying it, it becomes possible to heat-shrink the synthetic resin, and to easily create a retainer wire with a plastic part along the clearance on the tooth mold on the model.
- the applied temperature may be either dry heat or wet heat.
- the retainer wire 1 of the present invention causes heat shrinkage by heating at a relatively low temperature and follows the tooth shape, so that the work time is greatly shortened and the retainer fits the tooth shape more. Wire can be easily manufactured.
- the material of the metal wire 12 is selected from those having corrosion resistance and capable of easily forming a plastic cache.
- stainless steel nickel cobalt alloy, nickel chromium alloy
- a titanium alloy or the like is preferably used.
- the free end of the metal wire 12 of the retainer wire 1 of the first embodiment 1 is fixed to the base portion 21, and as a result, the retainer wire 1 is looped around a plurality of teeth, including teeth that have undergone orthodontic treatment.
- the metal wire is passed through the socket in which the screw portion fixed to both ends of the labial line and the other screw portion screwed with the screw portion are engraved. Since it is connected to the labial line, it can be adjusted so that the labial line follows the dentition by adjusting the socket (joint) screw, so it is necessary to form a loop like a conventional retainer wire There is no. Therefore, according to the present invention, there is an advantage that the labor for assembling the loop becomes unnecessary, the technique for assembling the loop becomes unnecessary, and the technique for finely adjusting the loop becomes unnecessary.
- the labial line and the metal wire are fixed to the labial line and another screw that is engaged with the screw part. Bend into a metal wire (be The labial line will naturally follow the dentition even if it is applied. For this reason, if the side of the labial line to the anterior dentition is loose, just adjust by turning the socket so that the contact surface of the labial line with the dentition is aligned with the dentition. Can do.
