V-shaped cavity filling is a common dental restoration technique, which is suitable for the caries of anterior teeth or premolars near the occlusal surface of the central pole. When filling and preparing V-shaped holes, some important requirements need to be met to ensure the quality and durability of filling and repairing.

1, filling material selection:

Choosing suitable filling materials is very important for the success of filling and restoration. Common filler materials are composite resin and glass ion filler. Composite resin has good aesthetics and plasticity, which is suitable for the restoration of anterior teeth, while glass ion filling material has better restoration effect on premolars because of its better wear resistance and corrosion resistance.

2, to caries tissue:

Before filling and preparing the V-shaped hole, the rotten tissue must be thoroughly removed. The soft tissue of dental caries may lead to insufficient adhesion of filling materials, thus affecting the stability of restorations. Use high-speed surgical drill or laser to remove dental caries tissue and ensure complete removal.

3, increase the stability of the groove:

In order to increase the adhesion and stability of the filling material, it is necessary to form a stepped groove at the bottom of the V-shaped hole. By using a drill or laser with a specific shape, it can provide better fixed support for the filling material and reduce the risk of the filling material falling off.

4, control the shape and size of the hole:

When filling and preparing the hole, it is necessary to control the shape and size of the hole to ensure that it matches the size of the hole. The choice of filling material and repair time will be influenced by the size and shape of the hole. The hole is usually trapezoidal in shape, with the bottom facing the cheek and the top facing the tongue.

5, edge processing:

For V-shaped holes with edge defects, edge treatment is needed. This means removing the defective marginal tissue and restoring the marginal tissue to a smooth shape to ensure the sealing of the filling material and the stability of the teeth. Edge treatment can be done by scraping or using a special drill.

6. Layered filling of filler:

In order to ensure the sealing of filling and the stability of teeth, it is usually necessary to fill filling materials in layers. Each layer should be carefully compacted and leveled by the dentist to avoid gaps and cracks in the filling material.

7. Shaping and polishing after repair:

After filling and repairing, the repaired parts need to be shaped and polished. This is helpful to match the filling material with the natural tooth surface and improve the aesthetics and comfort of the prosthesis.

Matters needing attention in filling V-shaped holes

1. Thoroughly remove corrupt organizations: Before filling the V-shaped holes, the corrupt organizations must be thoroughly removed. This is the basis to ensure that the filling material has good dust chain force and stability. Use high-speed surgical drill or laser to remove dental caries tissue to ensure complete removal.

2. Control the shape and size of the hole: V-shaped holes are usually trapezoidal, with the bottom facing the cheek and the top facing the tongue. When preparing the hole for filling, the shape and size of the hole must be accurately controlled to adapt to the filling of the filling material. The size and shape of this hole will affect the selection of filling materials and the repair time.
