Description

Oral clinical tooth preparation special protective equipment

technical field

The invention relates to a special appliance for oral cavity clinical practice, in particular to a special protective appliance capable of protecting tongue and buccal tissues from damage during dental preparation in oral cavity clinical practice. the

Background technique

In the Department of Stomatology, when dental clinicians perform various tooth preparations in the patient's mouth, the burs that grind the teeth often accidentally damage the patient's tongue and buccal tissue. These increase the chance of infection, which will cause unnecessary damage and misery to the patient. At present, there are three clinical methods to solve this problem. One is to allow the patient to control the movement of the tongue body to prevent the tongue from being damaged by the bur touching the incisor; the other is to use an assistant to block the patient's tongue or cheek to prevent it The third is that the operator uses a mouth mirror to protect the tongue or cheek. The first method cannot be guaranteed to be effective due to the large difference in individual control ability of patients, and the effect is also uncertain. The second method can only be realized when an assistant uses the instrument, and it is often caused by the narrow local space of the oral cavity. The operation is inconvenient for the operator, and the third method is also inconvenient for the operator to operate. At present, there is no special protective device for preventing tongue and buccal tissues from being damaged except the above methods. the

Contents of the invention

Aiming at the problems existing in the current clinical tooth preparation in oral cavity, the present invention provides a special tooth preparation method for oral clinical tooth preparation that does not rely on assistants or operators, and does not rely on the patient's self-control of tongue movement to prevent damage to tongue and buccal tissues. Protective equipment. the

The technical scheme adopted in the present invention is:

A special protective device for oral clinical tooth preparation, characterized in that it is composed of a rubber retaining foot 1, a metal ring 2, a tongue guard 3 and a buccal guard 4, wherein: the tongue guard 3 and the buccal guard 4 are respectively placed At the straight positions on the upper and lower sides of the metal ring 2, the two metal feet 6 on the metal ring 2 are inserted into the rubber retention feet 1, and the tongue guard 3 and the cheek guard 4 are both arc-shaped and one side of the arc It is an arc-shaped concave surface, and the other side is an arc-shaped convex surface. The arc-shaped convex surface of the tongue guard 3 and the arc-shaped concave surface of the cheek guard 4 are respectively provided with slots 5 fitted with the metal ring 2. The tongue guard 3 And the cheek guard 4 is connected with the metal ring 2 through the slot 5 respectively.

Beneficial effects of the present invention : the present invention provides a protective device for the dentist to prevent the damage of the tongue and buccal tissues without relying on the assistant or the doctor himself, and without relying on the patient's self-control of the tongue movement, which is convenient for the dentist to carry out During tooth preparation, it prevents damage to the patient's tongue and buccal tissues, enhances the safety of clinical operations, and improves work efficiency.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings. the

A special protective device for oral clinical tooth preparation, as shown in Figure 1, Figure 2 and Figure 3, consists of a rubber retaining foot 1, a metal ring 2, a tongue guard 3 and a cheek guard 4, the tongue guard 3 and the cheek guard 4 The cheek guards 4 are respectively placed at the straight positions on the upper and lower sides of the metal ring 2. The two metal feet 6 on the metal ring 2 are inserted into the rubber retaining feet 1. The metal ring 2 is a symmetrical long oval shape. The surface is oblate, as shown in Figure 4. The shape of the rubber retention foot 1 matches the shape of the adjacent surface between the two teeth in the oral cavity. Both the tongue guard 3 and the cheek guard 4 are arc-shaped, and one side of the arc is concave and the other is arc-shaped. Convex surface; on the arc-shaped convex surface of the tongue guard 3 and the arc-shaped concave surface of the cheek guard 4, slots 5 fitted with the metal ring 2 are respectively provided, and the tongue guard 3 and the cheek guard 4 respectively pass through the slots 5 Connect with metal ring 2. the

When using the present invention to prepare the tooth body, when the tongue and cheeks need to be protected at the same time, the tongue guard 3 and the cheek guard 4 are placed on both sides of the metal ring 2 corresponding to the tongue and cheek tissues to be protected; When only the tongue needs to be protected, place the tongue guard 3 on the side of the metal ring 2 corresponding to the tongue to be protected; when only the cheeks need to be protected, place the cheek guard 4 on the side of the metal ring 2 corresponding to the cheek to be protected Afterwards, use large surgical hemostats to extend into the ring of the metal ring 2, and expand the ring to a certain extent along the horizontal direction of the ring, so that the present invention is placed on the required dentition position, the shape of the rubber retaining foot 1 It matches the shape of the adjacent surfaces between two teeth in the oral cavity, and can play a good role in retaining the present invention; after the tongue guard 3 and the buccal guard 4 are placed, the concave surface of the tongue guard 3 faces the patient's tongue side, and the buccal guard The convex surface of guard 4 is toward the buccal side of patient; The position that tongue guard 3 and buccal guard 4 are placed on metal ring 2 can be adjusted along the length direction of guard ring 2 as required; When the affected tooth is prepared, the tongue guard 3 and the buccal guard 4 can prevent the patient's tongue and buccal tissue from contacting the preparation bur, thereby protecting the patient's tongue and buccal tissue from being damaged by the bur. the
