DENTAL DAM PROTECTIVE DEVICE

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a dental dam protection device which restrains and protects the oral mucosa and the tongue during dental treatment.

2. Description of Related Art

During a treatment of a decayed tooth, a dentist treats the decayed tooth using a roller while holding a dental mirror in one hand, spreading a lateral portion of the tongue with the dental mirror, and now roulette with the other hand. An assistant sucks saliva and water with a suction tip while stretching the oral mucosa away from the dentist.

As described above, the roulette is used in the treatment of the decayed tooth, the oral mucosa and the tongue being removed. There is therefore a risk that the wheel may touch the tongue or the oral mucosa, for example when the patient suddenly moves his tongue to touch the psychologically affected site or if the assistant moves the suction tip.

To solve this problem, the creator of this invention has proposed a dental dam protection device which retains the oral mucosa and the tongue as a dam to protect the oral mucosa and the tongue (see patent literature 1).

This dental dam protector includes, for example, a pair of left and right dam protector bodies including curved plate-shaped portions, an elastic arc-shaped bridge portion connecting the bodies of the a dam protection device, and an inverted L-shaped abutment extending over a tooth-side edge portion of one of the bodies of the dam protection device. To treat a tooth with the dental dam protective device, the bodies of the dental dam protective device are arranged to sandwich the tooth to be treated and the dental dam protective device is positioned by hooking the abutment inverted L shape on the tooth. Once the dental dam protector is attached to the tooth, one of the dam protector bodies spreads the dental mucosa and the other dam protector body spreads the tongue. As a result, the wheel can no longer touch the oral mucosa or the tongue.

[Patent literature(s)]

Patent Literature 1: JPH03-000717U

For example, to treat a tooth on the lower jaw using the dental dam protection device of Patent Literature 1, the inverted L-shaped abutment is usually hooked on the medial side (the side of the tongue). of the tooth. Thus, to treat a tooth on the left and a tooth on the right, it is necessary to prepare not only a dental dam protective device with the abutment on the right body of the dental dam protective device and a dental dam protective device with abutment on the left body of the dental dam protective device, but also protective devices for molars, premolars, canines, adults and children. The manufacturing costs are therefore high for the molds, since several types of dental dam protective devices are required.

Further, although the dental dam protector of Patent Literature 1 is designed so that the position for fixing the inverted L-shaped abutment can be selected, it is cumbersome to change the abutment for each treatment. , because the thrust bearing is a very small component.

Given the above circumstances, an object of the present invention is to provide a dental dam protective device that can be easily and quickly attached to a tooth without increasing manufacturing costs.

One aspect of the present invention is a dental dam guard comprising a pair of left and right dam guard bodies arranged to sandwich a tooth, an arcuate bridge portion elastic connecting the bodies of the rubber dam protection device to each other and a pair of left and right abutments hooked on an occlusal surface of the tooth, in which one of the bodies of the rubber dam protection device bears against the oral mucosa, while the other body of the rubber dam protection device presses against the tongue. An interlocking edge portion is formed at a tooth side edge portion of each of the bodies of the rubber dam protector to interlock with a side surface of the tooth, one of the abutments extends at one of the bodies of the dike protection device and the other abutment extends at the level of the other body of the dike protection device.

When the dental dam protector of the present invention is attached to a tooth, one of the dam protector bodies retracts the oral mucosa while the other dam protector body retracts the tongue. As a result, treatment equipment, such as a roller, cannot touch the oral mucosa or the tongue.

Further, according to the dental dam protector of the present invention, the dental dam protector can be attached to either a left tooth or a right tooth, since each of the left and right bodies of the protector with dam is equipped with a stop. In other words, according to the present invention, the number of kinds of dental dam protectors can be reduced by half, because it is not necessary to prepare different dental dam protectors for the left teeth. and the right teeth. As a result, manufacturing costs for molds and the like can be reduced.

It should be noted that it is not necessary to hook the left and right abutments to the occlusal surface of a tooth at the same time. At least one of the stops can be hooked to the occlusal surface of the tooth.

Preferably, the interlocking edge portion includes a pair of leading and trailing bearing edge portions, which bear against the side surface of the tooth, and an opposing edge portion which faces the side surface of the tooth. the tooth with a gap between the pair of front and rear bearing edge portions.

If the interlocking edge portions of the bodies of the rubber dam protector are shaped to come into linear contact with a side surface of a tooth, it is difficult to adjust the orientation of the protector to dental dam attached to the tooth. On the other hand, if the pair of front and rear bearing edge portions of each body of the rubber dam protection device bears against a side surface of a tooth such that gaps are formed between these edge portions bearing surface and the lateral surface of the tooth, it is easy to rotate the dental dam protector around the tooth. The orientation of the dental dam protector can thus be adjusted even after the dental treatment dam protector has been attached to a tooth.

Further, because a wheel can be inserted into the gap created between the interlocking edge portion of the rubber dam body and a side surface of a tooth, a dentist can treat an area of the tooth close to the gumline when the dental dam protector is attached.

The dental treatment dam protection device according to the present invention makes it possible to create a space for the treatment of a tooth without a dentist or an assistant having to retract the oral mucosa or the tongue. This facilitates treatment and helps prevent a roller from touching the tongue or oral mucosa, which helps to alleviate anxiety for both the dentist and the patient.

DETAILED DESCRIPTION OF EMBODIMENTS

As shown on the and 2, a dental dam protector 10 according to one embodiment of the present invention comprises a pair of left and right protector bodies 1, 1, arranged to sandwich a tooth A, a portion of arcuate elastic bridge 6 which connects the bodies of the rubber dam protection device 1, 1 to each other, and a pair of left and right abutments 7, 7, which can be hooked on the occlusal surface of the tooth A, and is designed so that one body of the rubber dam protection device 1 presses against the oral mucosa B and the other body of the rubber dam protection device 1 presses against the tongue C.

Each body of the rubber dam protection device 1 includes a compression portion 2 having a curved plate shape, an interlocking edge portion 3 which interlocks with a side surface of a tooth A, an insertion hole 4 passing through the body of the dike protection device 1, and a projecting piece 5 provided on a rear side of the dike protection device body. The left and right dike protector bodies 1, 1 are arranged side by side with a gap between them.

The compression portion 2 is curved so that its rear side can curve outward, the outer edge portion of the compression portion 2 forming an arc.

The interlocking edge portion 3 is formed at the tooth A side edge portion of the body of the rubber dam protector 1. When the rubber dam protector 10 is attached to a tooth A, the portions 2 are arranged close to tooth A, so that the interlocking edge portions 3 are respectively arranged between the tooth A and the compression portions 2. Although the compression portion 2 and the edge portion of socket 3 are formed in one piece in the present embodiment, they can be separated from each other.

The interlocking edge portion 3 comprises a pair of front and rear bearing edge portions 3a, 3a, which bear against a side surface of the tooth A and an opposing edge portion 3b which is located between the pair front and rear bearing edge portions 3a, 3a and which faces the side surface of tooth A with a gap between them. The interlocking edge portion 3a has a triangular shape so as to be able to enter the gap between the teeth. The opposite edge portion 3b has the shape of an arc of a circle. The left and right interlocking edge portions 3, 3 have symmetrical shapes, facing each other. When the dental dam protector 10 is not attached to the tooth A, a tooth holding space D formed between the left and right interlocking edge portions 3, 3 is slightly narrower than the smaller of tooth A.

The insertion holes 4 are formed around the interlocking edge portions 3. The left and right insertion holes 4, 4 are arranged at positions so as to face each other with respect to a tooth A therebetween. . The tips e, e of the enlarging forceps E shown in the are inserted into the insertion holes 4, 4.

The protrusions 5 serve as protection and prevent the tip of the tongue from entering the treatment area from the gingiva side and they are formed at the edge portions of the tooth side A of the bodies of the protection device at dam 1, they are located anterior to tooth A (the lower side on the ). The projecting piece 5 has a rounded shape so as not to irritate the gums. The projecting part 5 can be made, for example, of a flexible part of the body of the dike protection device 1 on the rear side.

The arcuate elastic bridge portion 6 connects the left and right dyke protector bodies 1, 1 to each other on the inner side (the throat side). The circular arc elastic bridge portion 6 has a shape of Ω and is arranged so as to overlap a tooth A (the gum) on the internal side (the side of the throat) of the tooth A when the protection device is in place. dental dam 10 is attached to tooth A.

The stops 7 are erected at the level of the bodies of the dike protection device 1. As shown in the , the stopper 7 includes an outer screw portion 7a and a hook portion 7b extending from one end of the outer screw portion 7a in a lateral direction. The outer screw portion 7a is screwed into an inner screw hole (not shown) formed in the body of the dike protection device 1. The stopper 7 is thus adjusted in height (the position of the hook portion 7b) thanks to a rotation around the axis of the external screw portion 7a. Thus, when the hook portion 7b is brought to face a tooth A while the abutment 7 is adjusted in height if necessary, the hook portion 7b presses against the occlusal surface of the tooth A.

In the present embodiment, a stopper 7 is provided at each of the bodies of the left and right dike protection device 1, 1. In other words, a stopper 7 is erected at a body of the device dike protection device 1 and the other abutment 7 is erected at the level of the other body of the dike protection device 1.

For example, the dental treatment dam protector 10 is fabricated as follows. The left and right bodies of the dike protection device 1, 1 and the arcuate elastic bridge portion 6 are stamped as a single plate-shaped metal member so that the interlocking edge portions 3, 3 face outward. Next, the left and right bodies of the dike protection device 1, 1 are tilted so that the interlocking edge portions 3, 3 face each other, thereby giving the resilient bridge portion circular arc 6 a C shape.

In the following, it is described how the dental treatment dam protection device 10 is to be used.

First, the tips e, e of the enlargement forceps E are inserted into the insertion holes 4, 4 of the bodies of the rubber dam protection device 1, 1 (see ). The forceps E are then actuated in order to widen the holding space of the tooth D and the interlocking edge portions 3, 3 are positioned at the level of a tooth A which requires treatment. The forceps E are then actuated in order to gradually reduce the holding space of the tooth D and the tips e, e of the forceps E are removed from the insertion holes 4, 4. As a result, the tooth A is held between the interlocking edge portions 3, 3 because the restoring force exerted by the elastic bridge portion in an arc of a circle 6.

At least one of the pairs of abutments 7 is rotated so that the external screw portion 7a rises or descends relative to the screw hole, causing the hook portion 7b of the abutment 7 to catch on the occlusal surface of tooth A. This prevents the dental treatment dam protector 10 from moving to the gingival side. It should be noted that it is not necessary to hook both left and right abutments 7, 7 to the occlusal surface of tooth A at the same time. At least one of the abutments 7 can be hooked to the occlusal surface of tooth A. Whether to use the left or right abutment 7 depends on the shape and condition of the tooth A. In many cases, the abutment 7 on the tongue side is hooked to the occlusal surface of tooth A when the dental treatment dam protector 10 is attached to an upper tooth A.

Once the dental treatment dam protector 10 is attached to tooth A, the dental dam protector is rotated around tooth A to adjust the orientation of the dental dam protector 10. In the device dental treatment dam protective device 10 of the present embodiment, the front and rear bearing edge portions 3a, 3a of each body of the protective device 1 abut between a side surface of the tooth A and gaps are formed between these bearing edge portions 3a, 3a and the side surface of the tooth A. It is thus easy to adjust the orientation of the dental dam protective device 10 even when the dental treatment dam protective device 10 is attached to tooth A.

When the dental treatment dam protector 10 is attached to the tooth A, the compression portions 2, 2 come into superficial contact with the buccal mucosa B and the tongue C, pushing the buccal mucosa B and the tongue C away from each other. the proximity of tooth A. The compression portions 2, 2 are less likely to cause patient discomfort, since the compression portions 2, 2 have curved surfaces.

When tooth A is being treated with the dental treatment dam protector 10 attached to tooth A, an assistant can concentrate on aspirating the patient's saliva and water (e.g. water allowing to cool a part heated by the friction caused by a wheel or other) and the like using a suction nozzle. Saliva, water and the like thus accumulate less in the mouth, thereby reducing patient discomfort caused by saliva and the like and the patient swallows saliva and the like less frequently. By reducing the frequency of movement of the tongue C and throat, the risk that the wheel may touch part of the inside of the mouth can thus be reduced.

Further, when the dental treatment dam protector 10 is attached to a tooth A, the patient's oral mucosa B and tongue C are constantly kept apart. The dentist can thus concentrate on the treatment of the tooth A without having to worry about the oral mucosa AB and the tongue C. In addition, since a gap is formed between the interlocking edge portions 3 of each body of the rubber dam protector 1 and a side surface of a tooth A, the dentist can treat the tooth A by inserting a roller close to the gingiva even if the dental dam protector 10 is attached to the tooth A .

After the treatment of tooth A is completed, the expansion forceps E are actuated in the same manner as for the attachment of the dental treatment dam protection device 10, in order to expand and withdraw the dam protection device of dental treatment 10 of tooth A, thus ending the treatment.

As described above, when the dental dam protector 10 is attached to a tooth A, one of the bodies of the dam protector 1 spreads the oral mucosa B while the other body of the dam protector 1 spreads the tongue C. This prevents a wheel from touching the oral mucosa B or the tongue C.

Further, depending on the dental dam protector 10, the dental dam protector 10 can be attached to either a left tooth A or a right tooth A, since each of the left and right bodies of the protector 1, 1 is provided with the stopper 7. In other words, the number of types of dental dam protective devices 10 can be reduced by half because one dental dam protective device 10 can be used both for a tooth on the left A and for a tooth on the right A. This makes it possible to reduce the costs of manufacturing molds and the like.

Note that the present invention is not limited to the above embodiment. For example, the arcuate elastic bridge portion 6 can be attached as a separate element and the compression portions 2 can have a semicircular or circular shape.
