Embodiment 1

[0034] Such as Figure 1-3 As shown, this embodiment provides an integrally formed wedge, including a forming piece 1, a wedge 2 and a handle 21; Fixedly connected, the forming piece 1 and the wedge 2 are integrally formed, and both the forming piece 1 and the wedge 2 are made of transparent plastic.

[0035] When in use, the medical staff holds the handle 21, aligns the tip of the wedge 2 at the bottom of the gap between the teeth to be repaired, aligns the front edge of the molding piece 1 with the vertical gap of the teeth, and slowly pushes the integrated molding wedge until the molding piece 1 reaches Suitable shaping position, and form a reliable combination with the gap between the teeth; use the same method to place the integral molding wedge on the other side of the tooth to be repaired.

[0036] Further, a limiting block 22 is also included. The limiting block 22 is arranged between the end of the wedge 2 and the handle 21 . The cross-sectional area of ​​the limitin...

Embodiment 2

[0044] This embodiment provides an integrally formed wedge, the difference from Embodiment 1 is as follows:

[0045] Such as Figure 4 As shown, the forming piece 1 is flat, the wedge 2 is straight, the forming piece 1 passes through the center line of the wedge 2, and is suitable for the restoration of incisors.

[0046]Further, the front end of the wedge 2 is a tip, the wedge 2 first widens and then narrows from the front end to the middle, the width of the wedge 2 increases first and then decreases from the middle to the end, and the parts of the wedge 2 with different widths transition smoothly.

[0047] When in use, the medical staff holds the handle 21, aligns the tip of the wedge 2 at the bottom of the gap between the teeth to be repaired, and aligns the front edge of the molding piece 1 with the vertical gap of the teeth, and slowly pushes the integrated wedge until it reaches the width of the middle of the wedge 2. The smallest position, so that the one-piece wedge i...

Abstract

The invention discloses an integrally formed wedge, and belongs to the technical field of dental medicine. The wedge comprises a forming piece, a wedge body and a handle. The lower edge of the formingpiece is fixedly connected with the upper surface of the wedge body, the front end of the wedge body is a tip end, and the tail end of the wedge body is fixedly connected with the handle. The formingpiece is integrally formed with the wedge body, and the forming piece and the wedge body are made of a transparent plastic material. The wedge and the forming piece can smoothly enter the interdentalspace and reach the optimal closed position, and provide a good seal for a matrix filled in a tooth to ensure the therapeutic effect of the tooth decay. A medical worker does not need to put the appropriate type of the wedge body and the model of the forming piece, and greatly reduces the operation difficulty and the workload of the medical worker. The integrally formed wedge adopts the transparent plastic material with high strength, good toughness and low cost, is easy to shape, can be closely adhered to the tooth body to complete precise positioning and is good in light transmittance. A photocuring machine can be adopted for curing after the matrix is filled.

Description

technical field [0001] The invention relates to the technical field of dentistry, in particular to an integrally formed wedge. Background technique [0002] In daily life, when tooth tissue defects are caused by dental caries, trauma, etc., it needs to be repaired to restore its shape and function. Before filling the teeth, the doctor will conduct a comprehensive oral examination of the patient, and formulate the best filling restoration plan according to the degree of dental lesions of the patient. Before filling the tooth, it is necessary to make a cavity for the carious tooth body, remove the diseased tissue, and establish a good retention force and resistance shape, so as to avoid the filling body from breaking, falling off and not dense, causing secondary caries, affecting the gums and healthy teeth body tissue. [0003] After the cavity is prepared, the restoration of the tooth begins. During operation, the forming sheet is first placed between the two teeth, and th...
