Description

  The present invention relates to an occlusal paper holder that holds occlusal paper for inspecting occlusion of a dentition.

  It is very important to confirm and adjust the occlusion in dental treatment. Normally, occlusion paper is used for occlusion confirmation, but it is generally difficult to use occlusion paper alone, so it is common to hold the occlusion paper holder and insert it into the oral cavity.

  However, when dental treatment is performed with general anesthesia or intravenous anesthesia, the tongue is relaxed and enlarged due to the action of anesthetics, which obstructs the occlusion, and it is very difficult to confirm the occlusion using the conventional occlusal paper holder.

Japanese Patent No. 2732179 Design registration No. 119449

  The occlusal paper holders disclosed in Patent Document 1 and Patent Document 2 have a function of attaching and holding the occlusal paper, but have a function of a tongue depressor for pushing the tongue that prevents occlusion into the interior. If the tongue comes out ahead of the dentition due to the action of an anesthetic or the like, the occlusion cannot be confirmed.

  Then, an object of this invention is to suppress the obstruction | occlusion of the occlusion confirmation by a tongue.

  In order to solve the above-described problem, an occlusal paper holder according to the present invention includes an occlusal paper sandwiching portion that holds an occlusal paper sandwiched between an upper arm and a lower arm that are openable and closable, and one of the occlusal paper sandwiching portions. A gripping portion connected to the end portion, a tongue depressor that is provided apart from the bite paper pinching portion and pushes in the tongue, and one end portion of the bite paper pinching portion is an end opposite to the gripping portion And a connecting portion connected to the tongue depressor at the other end.

  According to the present invention, it is possible to suppress obstruction of occlusion confirmation by the tongue.

  Several embodiments of the occlusal paper holder according to the present invention will be described with reference to the drawings. This embodiment is merely an example, and the present invention is not limited to this. The same or similar components are denoted by the same reference numerals, and redundant description is omitted.

[First Embodiment]
FIG. 1 is a top view of the occlusal paper holder according to the first embodiment of the present invention in a use state in which the occlusal paper according to the first embodiment is held. FIG. 2 is a front view of the occlusal paper holder according to the present embodiment. FIG. 3 is a side view of the occlusal paper holder according to the present embodiment.

  The occlusal paper holder according to the present embodiment is used when examining the engagement when the upper and lower tooth rows 91 of a person are closed. That is, the occlusal paper holder is used for occlusion confirmation. The occlusion confirmation is checked using an occlusal paper 90 that changes color due to the pressure between upper and lower teeth. The human tooth row 91 has a substantially semicircular arc shape.

  The occlusal paper holder according to the present embodiment includes an occlusal paper sandwiching portion 20, a gripping portion 10, a tongue depressor 41, and a connecting portion 30. The occlusal paper sandwiching portion 20 has an upper arm 21 and a lower arm 22 that face each other. The occlusal paper sandwiching portion 20 is formed in a substantially arc shape along the human tooth row 91. The upper arm 21 and the lower arm 22 are provided so as to be freely opened and closed.

  The grip 10 is connected to the occlusal paper sandwiching portion 20 at the center of the occlusal paper sandwiching portion 20, that is, at the ends of the right arm and the left arm of the occlusal paper sandwiching portion 20. The grip portion 10 is, for example, two vertically long and thin flat plates 11, and opposite ends of the occlusal paper sandwiching portion 20 are coupled to each other. For example, a spring 12 is provided between the two flat plates of the grip 10 and is biased in a direction in which the two flat plates are separated.

  The tongue depressor 41 is provided so as to be spaced from the left and right occlusal paper sandwiching portions 20 so as to sandwich the tooth row 91. The tongue depressor 41 as a whole is formed in a substantially arc shape along the human tooth row 91 on a plane including the held occlusion paper.

  One end portion of the connecting portion 30 is connected to an end portion on the opposite side to the grip portion 10 of the occlusal paper sandwiching portion 20. The other end of the connecting portion 30 is connected to the tongue depressor 41. The connection part 30 is located in the back | inner side of the both ends of the dentition 91, ie, the back tooth (backmost molar) which exists in the back. Here, the back side means the back when the mouth is the front of the oral cavity.

  The connecting portion 30 includes an upper connecting portion and a lower connecting portion connected to each of the upper arm 21 and the lower arm 22. The tongue depressor 41 includes an upper tongue depressor and a lower tongue depressor connected to the upper coupling portion and the lower coupling portion, respectively.

  The occlusal paper holder of the present embodiment is made of, for example, stainless steel.

  Next, an occlusal confirmation method using the occlusal paper holder of the present embodiment will be described.

  When confirming occlusion, first, the occlusion paper 90 is moved to a predetermined position while holding the grip portion 10 by hand. Thereafter, the upper and lower flat plates 11 of the gripping part 10 are sandwiched by hand, so that the upper arm 21 and the lower arm 22 of the occlusal paper clamping part 20 are closed with the occlusal paper 90 interposed therebetween. In this way, the occlusal paper 90 is held between the upper arm 21 and the lower arm 22 of the occlusal paper sandwiching portion 20.

  Next, the occlusal paper holder is inserted into the oral cavity with the occlusal paper 90 sandwiched between the occlusal paper sandwiching portions 20. The occlusal paper holder is inserted to a position where the connecting portion 30 is on the far side of the innermost portion of the tooth row 91. In a state where the connecting part 30 is pushed inward from the innermost part of the tooth row 91, the patient closes the upper and lower teeth. Thereby, the occlusion state is recorded on the occlusion paper 90. Thereafter, the patient opens the upper and lower teeth, takes out the occlusal paper holder, and reduces the force to pinch the gripping portion, thereby releasing the occlusal paper 90 from the state sandwiched between the upper arm 21 and the lower arm 22.

  The tongue depressor 41 is formed in a substantially arc shape inside the tooth row 91. That is, the tongue depressor 41 includes a side tongue pressure portion that pushes the side of the tongue inward, and a front tongue pressure portion that pushes the tongue toward the pharynx. For this reason, the tongue is pushed into the pharynx side during occlusion confirmation.

  It is very important to confirm and adjust the occlusion in dental treatment. When performing a dental procedure under general anesthesia (including intravenous anesthesia), the tongue may relax and enlarge due to the action of the anesthetic, and the occlusion may be hindered. For example, the tongue may protrude forward from the dentition due to the action of an anesthetic.

  However, when the occlusal paper holder of the present embodiment is used, since the tongue is pushed into the pharynx during occlusion confirmation, it is possible to suppress obstruction of occlusion confirmation by the tongue. As a result, occlusion confirmation can be performed safely even when the patient is anesthetized. In addition, since it is not necessary to use a tongue depressor separately, the occlusion confirmation can be performed easily and reliably. That is, it is not necessary for another person to insert the occlusal paper holder into the oral cavity while one person holds the tongue with a single tongue depressor. Therefore, the time required for occlusion confirmation can also be shortened. The burden on the patient is also reduced.

[Second Embodiment]
FIG. 4 is a perspective view of a second embodiment of the occlusal paper holder according to the present invention.

  In the occlusal paper holder of the present embodiment, the occlusal paper pinching portion 20 is substantially linear. This occlusal paper holder is used when checking the occlusion on either the left or right side of the dentition 91 (see FIG. 1).

  The occlusal paper holder of the present embodiment has an occlusal paper pinching portion 20, a gripping portion 10, a tongue depressor 42, and a connecting portion 30. The occlusal paper sandwiching portion 20 has an upper arm 21 and a lower arm 22 that face each other. It can be opened and closed freely.

  The grip 10 is connected to the occlusal paper sandwiching portion 20 at the end of the occlusal paper sandwiching portion 20. The grip portion 10 is, for example, two vertically long and thin flat plates 11, and opposite ends of the occlusal paper sandwiching portion 20 are coupled to each other. The flat plate 11 on the upper side of the grip 10 is connected to the lower arm 22. The lower flat plate 11 of the grip 10 is connected to the upper arm 21. The two flat plates 11 of the grip portion 10 are biased toward the opening side. That is, the occlusal paper pinching portion 20 is in a closed state when the grip portion 10 is not gripped by hand.

  The tongue depressor 42 is provided so as to be spaced from the occlusal paper sandwiching portion 20 so as to sandwich the tooth row 91. The tongue depressor 42 includes only a side tongue pressure portion that pushes the side of the tongue inward. For example, the tongue depressor 42 is formed in a substantially straight spoon shape on a plane including a held occlusion paper (not shown).

  One end portion of the connecting portion 30 is connected to an end portion on the opposite side to the grip portion 10 of the occlusal paper sandwiching portion 20. The other end of the connecting portion 30 is connected to the tongue depressor 42. The connection part 30 is located in the back | inner side rather than the end part of the tooth row 91, ie, the back tooth which exists in the back.

  The connecting portion 30 includes an upper connecting portion and a lower connecting portion connected to each of the upper arm 21 and the lower arm 22. The tongue depressor 42 has a slit extending horizontally on the connecting portion 30 side, and the upper and lower sides of the slit are connected to the upper connecting portion and the lower connecting portion, respectively.

  When the occlusal paper holder of the present embodiment is used, since the tongue is pushed into the dentition during occlusion confirmation, it is possible to suppress obstruction of occlusion confirmation by the tongue. In the present embodiment, both sides of the occlusal paper sandwiching portion 20, that is, the end portion on the gripping portion 10 side and the end portion on the connecting portion 30 side are closed on the side where no pressing force is applied to the gripping portion 10. It will be energized and the holding power of the bite paper will increase. Further, by switching the upper and lower sides, it is possible to confirm the occlusion of either the left or right dentition, and the operability is good for confirming only the desired dentition portion.

[Third Embodiment]
FIG. 5 is a perspective view of a third embodiment of the occlusal paper holder according to the present invention.

  In the occlusal paper holder of the present embodiment, the occlusal paper pinching portion 20 is substantially linear. This occlusal paper holder is used when checking the occlusion on either the left or right side of the dentition 91 (see FIG. 1).

  The occlusal paper holder of the present embodiment has an occlusal paper sandwiching portion 20, a gripping portion 10, a tongue depressor 43, and a connecting portion 30. The occlusal paper sandwiching portion 20 has an upper arm 21 and a lower arm 22 that face each other. It can be opened and closed freely.

  The grip 10 is connected to the occlusal paper sandwiching portion 20 at the end of the occlusal paper sandwiching portion 20. The grip portion 10 is, for example, two vertically long and thin flat plates 11, and opposite ends of the occlusal paper sandwiching portion 20 are coupled to each other. The flat plate 11 on the upper side of the grip 10 is connected to the lower arm 22. The lower flat plate 11 of the grip 10 is connected to the upper arm 21. The two flat plates 11 of the grip portion 10 are biased toward the opening side. That is, the occlusal paper pinching portion 20 is in a closed state when the grip portion 10 is not gripped by hand.

  The tongue depressor 43 is provided so as to be spaced from the occlusal paper sandwiching portion 20 so as to sandwich the tooth row 91. The tongue depressor 43 is formed in a substantially arc shape along the tooth row 91 (see FIG. 1) on a plane including a held occlusion paper (not shown).

  One end portion of the connecting portion 30 is connected to an end portion on the opposite side to the grip portion 10 of the occlusal paper sandwiching portion 20. The other end of the connecting portion 30 is connected to the tongue depressor 43. The connection part 30 is located in the back | inner side rather than the end part of the tooth row 91, ie, the back tooth which exists in the back.

  The connecting part 30 is composed of an upper connecting part connected to the upper arm 21. That is, the connecting portion is connected only to the upper arm 21. The tongue depressor 43 is connected to the upper coupling part.

  When the occlusal paper holder of the present embodiment is used, since the tongue is pushed into the pharynx side at the time of occlusion confirmation, it is possible to suppress obstruction of occlusion confirmation by the tongue. In the present embodiment, since the connection between the occlusal paper sandwiching portion 20 and the connecting portion 30 and the connection between the connecting portion 30 and the tongue depressor 43 are each one place, the manufacturing is easy.

  The occlusal paper holder of the present embodiment can check the occlusion of either the left or right dentition by switching the top and bottom. Further, the connecting part 30 may be configured to include a lower connecting part connected to the lower arm 22.
