1 and 2, the dental multi-function impression tray of the present invention may be any one of a mandibular tray 1000 mounted on the lower jaw and a maxillary tray 1000 ′ mounted on the upper jaw.

The dental multifunctional impression tray, which is one of the maxillary tray 1000 and the mandibular tray 1000', may include outer frames 100 and 100', and inner frames 200 and 200'. Each frame can be made of synthetic resin, metal, or a combination thereof.

The outer frame 100 may have a shape corresponding to the arrangement of teeth. It is preferable that the outer frame 100 has a'U' shape. The inside of the outer frame 100 may be hollow to form an impression material filling space (S). The outer frame 100 may have an open upper side so that the teeth are inserted into the filling space S. The outer frame 100 may have a shape in which the side surfaces of the left and right ends are open, but is not limited thereto. A tooth may be inserted into the filling space (S).

The outer frame 100 may have a plurality of through holes penetrating the side of the outer frame 100 on its side. This through hole stably accommodates the soft-filled impression material, and allows the impression material to go out when teeth are inserted, so that the impression material pressure is lowered.

The

outer frames

100 and 100 ′ may have

open holes

110 and 110 ′.

The open hole 110 may be formed through the bottom surface of the outer frame 100, which is one side symmetrical with the open upper side of the outer frame 100.

The inner frame 200 may be seated on the bottom surface of the outer frame 100.

The inner frame 200 may be detachably attached to the open hole 110 of the outer frame 100. The inner frame 200 may be attached to and detached from the open hole 110 to open and close the open hole 110. The operator may install the inner frame 200 in the open hole 110 and fill the impression material, thereby accommodating the impression material in the filling space S, and prevent leakage of the received impression material.

The inner frame 200 may include a through hole 200H and a hole cover 210.

The through hole 200H may be formed through the inner frame 200.

The hole cover 210 may cover the through hole 200H. The hole cover 210 may be formed to have a diameter smaller than that of the through hole 200H. The hole cover 210 may be detachably attached to the inner frame 200 (or the through hole 200H) in order to form the through hole 200H in the inner frame 200.

The hole cover 210 and the through hole 200H may be attached and detached in various ways.

For example, the hole cover 210 and the through hole 200H may be attached and detached by the connection rod 210-1 provided in the inner frame 200.

The connection rod 210-1 may have a bar shape connecting the edge of the hole cover 210 and the inner surface of the through hole 200H. It is preferable that the connection rod 210-1 includes two or more connection bars connecting the pair of hole covers 210 and the through hole 200H.

The thickness of the hole cover 210 and the connection rod 210-1 may be equal to or smaller than the thickness of the hole cover 210. It may be more preferable that the thickness of the connection rod 210-1 is smaller than the thickness of the hole cover 210, because it is more advantageous in removing the hole cover 210 to be described later.

It is preferable that the through hole 200H and the hole cover 210 are arranged such that their concentricity is close to the center of the tooth. It is preferable that the pair of the through hole 200H and the hole cover 210 is provided in a plurality of pairs.

The operator may remove any one hole cover 210 of the plurality of hole covers 210 to open the through hole 200H. For example, the operator may remove the hole cover 210 from the through hole 200H by an operation of easily breaking the connection rod 210-1.

Referring to FIG. 5, as another example of attaching and detaching the hole cover 210 and the through hole 200H, the hole cover 210 may be rotationally coupled to the inner frame 200.

To this end, a pair of fastening protrusions 211 may protrude on both sides of the hole cover 210. The fastening protrusion 211 may be screwed and/or force-fitted with a portion in which the through hole 200H of the inner frame 200 is disposed.

The inner frame 200 may include a contact protrusion 203 formed along the inner surface of the through hole 200H. The contact protrusion 203 may be formed so that the diameter of the through hole 200H gradually decreases in the circumferential direction of one side of the through hole 200H.

When the hole cover 210 rotates to one side, the fastening protrusion 211 of the hole cover 210 may be closely supported by the contact protrusion 203. The hole cover 210 may be fixed to and attached to the inner frame 200 by coupling the fastening protrusion 211 and the close contacting protrusion 203 such as force fitting or screwing.

The inner frame 200 may have a locking protrusion 204 formed at the end of the contact protrusion 203. The locking projection 204 may prevent the hole cover 210 from rotating any more.

When the hole cover 210 rotates in the opposite direction, the hole cover 210 may be separated from the inner frame 200.

When taking an impression, impression coping can be used. Impression coping refers to a bar, screw, or a combination thereof indicating the position of an implant when taking an impression in order to accurately reproduce the exact position of the implant in a model other than the oral cavity. One end of the coping is often penetrated outside the impression tray, in order for the operator to easily identify the location of the person being treated with the eye. For this, the operator artificially creates an implant hole in the tray where the coping protrudes using a tool.

In this embodiment, the opened through hole 200H may allow one end of the impression coping to penetrate the inner frame 200.

By removing the connecting rod 210-1 or separating the fastening protrusion 211 and the contact protrusion 203, a through hole 200H through which the impression coping can pass can be easily provided. In the conventional case where the bottom surface of the tray is removed with a nipple, etc., through holes are formed wider than necessary parts, whereas in the case of this embodiment, the pre-processed through holes 200H provide an appropriate through area to penetrate unnecessarily. It is possible to prevent further formation of the part. An appropriate penetration area prevents the impression material from being excessively discharged to the outside of the tray, so that an accurate impression can be obtained.

The multifunctional dental impression tray may further include traction rods 300 and 300'.

The traction rod 300 may be mounted on the outside of the outer frame 100. When the outer frame 100 is inserted into the oral cavity, the traction rod 300 is preferably disposed in the center of the outer frame 100 with respect to the left and right ends so that the traction rod 300 remains exposed to the outside of the oral cavity. Do.

One side of the traction rod 300 may be provided with a gripping portion 310 capable of being gripped by the operator. The operator may insert the outer frame 100 into the oral cavity while holding the gripping portion 310 so that the teeth are inserted into the filling space S.

1 and 3, the outer frame 100 may include a mounting groove 111, and the inner frame 200 may include a coupling protrusion 201.

The mounting groove 111 may be formed to be recessed so that one side is opened at the edge of the open hole 110. It is preferable that an open side of the mounting groove 111 is opened in a downward direction of the outer frame 100. A plurality of mounting grooves 111 may be formed at regular intervals along the edge of the open hole 110

The coupling protrusion 201 may be formed to protrude from the edge of the inner frame 200. The coupling protrusion 201 may be fitted into the mounting groove 111. As the coupling protrusion 201 is fitted into the mounting groove 111, the inner frame 200 and the outer frame 100 may be strongly coupled. Since the inner frame 200 is supported by the open hole 110, the inner frame 200 can be prevented from being easily separated from the outer frame 100.

The outer frame 100 may further include a guide rod 120 disposed on an inner surface.

The guide rod 120 may guide the coupling position of the coupling protrusion 201 when the inner frame 200 is inserted into the open upper side of the outer frame 100. The coupling protrusion 201 may be guided to the mounting groove 111 while being in contact with the guide rod 120.

The guide rod 120 may be formed to form a pair of guide walls at left and right ends of the mounting groove 111. The coupling protrusion 201 may be guided to the insertion position of the inner frame 200 as it flows into between a pair of guide walls spaced apart from the guide rod 120.

A position guide protrusion 112 for guiding the insertion position of the inner frame 200 may be formed to protrude on the inner side of the open hole 110. A location guide groove 290 into which the location guide protrusion 112 is inserted may be formed at the edge of the inner frame 200.

The position guide protrusion 112 and the position seating groove 290 may be prevented from shifting when the inner frame 200 is inserted into the open hole 110.

1 to 2, the outer frame 100 may be disposed in the open hole 110 and may have a support rod 130 crossing the open hole 110.

When the inner frame 200 is inserted into the open hole 110, one side of the inner frame 200 may be seated on one side of the support rod 130. The support rod 130 may support the seated inner frame 200.

As described above, the opening direction of the mounting groove 111 may be opened in a direction opposite to the insertion direction A of the inner frame 200. When the coupling protrusion 201 is inserted into the mounting groove 111, the support rod 130 may exert a force pushing the inner frame 200 in the opposite direction to the insertion. Since the opening direction of the mounting groove 111 is opened in a direction opposite to the force acting by the support rod 130, the coupling protrusion 201 may be in close contact with the mounting groove 111. Accordingly, the inner frame 200 may be firmly fixed to the open hole 110.

It is preferable that the support rod 130 is formed of a material having elasticity. The support rod 130 may be integrally formed with the outer frame 100.

Referring to FIG. 4, the traction rod 300 may be installed on the outer frame 100 so as to be rotatable in the vertical direction. The traction rod 300 may be coupled to the outer frame 100 by hinge coupling supported on a separate rotation shaft.

The traction rod 300 may further include a traction support rod 320.

The traction support rod 320 is formed at one end of the traction rod 300 and may rotate integrally with the traction rod 300. When the traction support rod 320 is disposed at the end in one direction, the traction support rod 320 may support the inner frame 200.

The traction support rod 320 may press or release one side of the inner frame 200 according to its rotation direction. With this pressurization or release, the traction support rod 320 may assist in attaching and detaching the inner frame 200. The direction in which the traction support rod 320 presses one side of the inner frame 200 is opposite to the opening direction of the mounting groove 111. Therefore, when the traction rod 300 rotates so that the traction support rod 320 presses the inner frame 200, the coupling protrusion 201 is more closely contacted with the mounting groove 111, making the inner frame 200 more robust. It is fixed properly.

The inner frame 200 may further include a seating groove 202 in which the traction support rod 320 is seated. The mounting groove 202 may have a protruding protruding protruding protrusion 202-1 coupled to the end of the traction support rod 320.

At the end of the traction support rod 320, a locking protrusion 311 seated on the locking protrusion 202-1 may protrude. The locking protrusion 311 and the locking protrusion 202-1 may prevent the traction rod 300 from rotating in the opposite direction when the traction support rod 320 supports the inner frame 200.

And, the outer frame 100 ′, the inner frame 200 ′, and the traction rod 300 ′ of the present invention are detailed descriptions of the corresponding outer frame 100, the inner frame 200 and the traction rod 300, respectively Conforms to
