DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for easily opening an upper lip or a lower lip to view a surgical field when treating an anterior tooth, performing a surgical operation, or taking an impression. The present invention relates to a dental lip indenter used for the purpose of protecting skin.

[0002]

2. Description of the Related Art When performing treatment or surgery on anterior teeth or the like, if the upper lip or the lower lip is obstructed, conventionally, the lips have been pushed open with fingers of a doctor or an assistant. For that reason,
It is difficult to look directly at the surgical field, and water or the like gushing from the handpiece of the tooth cutting tool scatters on the patient's face or the like. For example, when cutting the anterior teeth of the upper jaw, there is a danger that water spouted from the instrument may enter the patient's nostrils, eyes, etc., so that the face is appropriately covered with a surgical cloth, a towel, etc., but that is still insufficient.

[0003]

As described above, the lips interfere with the treatment of the front teeth and the like, and it is often the case that the doctor pushes the lips open with his / her fingers. There may be adverse effects. For example, in the prosthetic treatment of a tooth, it is necessary to obtain an accurate impression, but there is a case where a good impression cannot be obtained due to hindrance to a lip.

[0004] When cutting the anterior teeth of the upper jaw, it is dangerous because water spouted from the instrument contains teeth and metal cutting powder and may enter the nostrils and eyes. In such a case, it is prevented by covering the patient's face with a surgical cloth or a towel or the like, but this is incomplete and gives the patient discomfort. Therefore, the cover portion of the lip indenter protruding outside the oral cavity serves as a fountain defense wall, so that it is prevented from scattering on the face.

An object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to secure a surgical field and prevent damage such as water spouting from a handpiece of a cutting instrument.

[0006]

The dental lip indenter of the present invention has such a strength that it can be inserted into the inside of the lip of the oral vestibule to push open the lip, and it can be applied to the alveolar part of the patient as appropriate. It is made of a plate material that can be bent along and comprises an insertion portion formed in a size that can be inserted into the inside of the lip, and a grip portion for finger holding a cover portion protruding outside the oral cavity continuous with it, In addition, the corners on the left and right sides of the upper edge of the insertion portion are constricted to form a boundary with the cover portion.

[0007] By providing a concave groove or a convex ridge along the periphery of the insertion portion, the jetted water falls along the mouth into the oral cavity. The shape of the unevenness is arbitrary.

The lip indenter is made of polyethylene, polypropylene, polyamide, acrylic resin, polystyrene, or polyurethane shape memory resin, and aluminum,
It can be formed of any other metal such as stainless steel, silver alloy, shape memory alloy, or any other material that can be disinfected with paper, wood, or the like. The shape is free in size, shape, etc. as long as it meets the above-mentioned purpose.

[0009]

The dental lip indenter of the present invention inserts both ends of the insertion portion into the vestibule inside the lip along the alveolar portion.
At this time, the edge of the lip indenter is made to follow the alveolar gingiva. Since the lips cover the insertion portion, in the case of the upper jaw, when the lip indenter is turned upside down, the lips are lifted to the nose side, and the front teeth can be clearly seen as a whole. Similarly, in the case of the lower jaw, the visual field is widened by pressing the lower lip downward with the lip indenter. Therefore, it is possible to prevent the cutting operation by the cutting tool of the anterior teeth portion and the trouble of the lips at the time of obtaining the impression for the oral surgery operation or the prosthetic treatment.

[0010] There is a mechanism for jetting water to cool frictional heat during tooth cutting from a handpiece of a tooth cutting instrument. Teeth and metal cuttings are mixed in the fountain. Therefore, in the upper anterior teeth, there is a risk that the splatters may scatter on the face and enter the nostrils and eyes. The lip indenter then acts as a barrier between the oral surgical field and the face. In addition, water that has collided with the lip indenter flows down into the oral cavity along a groove or the like. Therefore, labor for covering the face with a surgical cloth or wiping water with a towel or the like can be omitted. As a result, dental treatments and the like can be performed more smoothly and accurately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a dental lip indenter according to the present invention will be described with reference to FIGS. FIG. 1 shows a lip indenter made of a linear flat plate, which is divided into upper and lower parts, and an insertion part 2 is provided on one side which can be inserted into the oral vestibule inside the lip, and the periphery of the lip depressor is formed by bending the alveolar part gingiva. A curved edge 3 is provided in a generally conforming shape.
Due to the individual differences, the plate is bent and adapted to the alveolar part of each patient for later use. Insert support portions 4a, 4 of a width that can be inserted between the gum and the cheek at both ends thereof
b is made. Constrictions 3a and 3b are provided between the upper cover 5 and the corners of the mouth. Since the cover 5 has a role of a barrier between the mouth and the face, it is larger than the insertion portion, and is formed in a size and shape capable of preventing the spray water from the handpiece from scattering on the face. Also, at both ends of the cover, grip portions 6a for holding the main body with fingers,
6b is provided.

A U-shaped groove (FIG. 2) extending from 4a to 4b is formed substantially at the center of the insertion portion 2 along the lower edge 3 so that the fountain hits the lip indenter and flows down along the groove. Runs down into the mouth from both sides. Water accumulated in the oral cavity is removed by dental vacuum. The shape of the groove may be any of U and V shapes. Also, it may be a jetty.

With the lip indenter 1 configured as described above, for example, when opening the upper lip, the gripper 6 is held and the surface of the concave groove 7 is set to the surface, that is, the lower jaw side, and the upper alveolar part gingiva and cheek are connected. If the insertion support portions 4a and 4b are inserted between the insertion rim and the curved edge 3, the lip indenter overlaps below the upper lip. In this state, when the lip indenter is pushed up to the nose side, the maxillary anterior teeth are widely opened as shown in FIG. Fig. 4-Dental treatment
As shown in FIG. 2, since the face is almost upward, the lip depressor is slightly perpendicular to the operation surface.

Since the insertion supporting portions 4a and 4b are supported inside the cheeks, the assistant holds the grip 6 of the cover to keep the upper lip pushed open, so that the front teeth of the upper jaw can be maintained. The whole can be sufficiently exposed. In this state, it is possible to smoothly and accurately perform treatment of anterior teeth, surgical operation, or acquisition of an impression in tooth prosthesis without disturbing the upper lip.

Further, as described above, when the handpiece of the cutter 8 is used, the spouted water is blocked by the cover 5 and is prevented from splashing on the face such as the nostrils and eyes, thereby protecting from danger and discomfort. be able to. The water that has hit the lip indenter 1 flows down the groove 7 into the oral cavity. The accumulated water is drained with a suction device.

The size and shape of the insertion portion and the cover are as follows.
The shape of the alveolar gingiva is arbitrary and varies depending on the individual, so that the lip indenter 1 is adapted to bend by slightly bending the central portion of the lip indenter 1 in order to align the curved edge 3 of the insertion portion. I can do it. The shape of the concave groove is U-shaped, V-shaped or the like. In addition, it is possible to provide them not only on one side but also on both sides. It is also convenient to provide the gripping parts not only on one side but also on both sides. FIG. 2 is a side view. FIG. 3 is a plan view, and 1-1 is a horizontal plan view. 1-2 is a figure slightly curved from the center.

The groove 7 provided in the lip indenter 1 can be replaced with a convex 7a. The purpose for guiding the flow of the water 9 does not change.

[0018]

As described above, in the dental lip indenter of the present invention, the insertion support portions provided on both sides of the insertion portion are inserted between the gingiva and the cheek, and the curved edge of the insertion portion is formed on the surface of the gingiva. The upper lip or lower lip is moved to open, and the upper lip or lower lip is pushed open to expose the front teeth. Maintaining the condition helps to perform the treatment and treatment of the part accurately and accurately.

As described above, when cutting teeth, water spouts out of the handpiece and often scatters on the face, but the lip indenter serves as a protective wall, and water splatters on the face, making the patient uncomfortable. And prevent danger of entering the nostrils and eyes. Also, with a slight distance from the curved edge, a concave groove or a ridge is provided along the curved edge, and water that has hit the lip indenter,
It flows down smoothly into the oral cavity. In addition, it is easy to provide concave grooves and convex stripes on both sides of the lip indenter.

The insertion edge of the dental lip indenter according to the second aspect has a slightly curved line along the alveolar part gingiva, but there is an individual difference in the gingival part. Since it is necessary to bend around the center of the lip indenter in order to adapt, it can be bent as appropriate.
