What Is A Dental Sectional Matrix System?

A dental sectional matrix is a specialized system that allows the dentist to restore the contact point on class II cavities.

The system consists of two elements: the sectional matrix and the ring.

● The sectional matrix:

The sectional matrix is a small and thin piece of a metal alloy. It is slightly curved to simulate the tooth's natural interproximal shape. The matrix is placed between the tooth that needs to be restored and its adjacent tooth.

● Singsing:

The ring is a medium-sized structure that secures and seals the lingual/palatal and buccal embraces of the sectional matrix.

The ring is made of metal. This turns it into a resistant tool that can be safely placed around the tooth without breaking. However, both ends of the ring are made from silicone to provide a comfortable and steady grip.

The ring can be reused and can also be sterilized on the autoclave. This prevents cross-contamination between patients.

Using a matrix system is easy. The dentist has to place the dental sectional matrix between both teeth and adjust and secure it using the ring. Nonetheless, the concave part of the matrix must face the tooth that will be restored.

However, there are a few aspects to consider while placing the system.

Also, the dentist must place a wooden wedge between the teeth after placing the matrix. This allows the matrix to adhere better to the gingival portion of the tooth. Therefore, creating a natural-looking restoration.

The dentist must also place the matrix without applying too much force. Otherwise, it might deform and affect the quality of the restoration.

Benefits Of Using A Dental Sectional Matrix

Using a dental sectional matrix system provides several benefits.

The matrix allows the dentist to create a more detailed and accurate anatomical contact point in any class II restoration. Additionally, it allows an appropriate smooth interphase between tooth structure and the dental composite in difficult areas.

Moreover, they are simple and easy to place. The sectional matrix system can be used even with a rubber dam placed to isolate the teeth. Besides, the system can be placed on the same tooth held by the isolation clamp. Nonetheless, the clamp must be flapless.
