Matrices are widely used by dentists around the world to restore missing tooth walls. Their use allows you to make a high-quality filling during the treatment of a carious cavity. Matrix systems not only facilitate the work of the doctor and allow you to give the patient's tooth an ideal shape, but also protect the periodontium surrounding it from injury.
Application of matrix systems
The tool allows you to restore the contact point quickly and easily. And this is very important for the distribution of the load during chewing. The main thing is the correct location of the tool and its correct fixation with wedges.
You can buy this tool in completely different shapes, types and sizes. Its application consists in the consistent observance of the following steps:
- the dentist inserts the instrument into the interdental space of the operated and adjacent teeth;
- temperature and pressure control is carried out with the help of special tubes introduced into the installation;
- after elimination of the matrix and wedges, the light polarization of the cavity is carried out;
- by supplying a filling substance through the tube, a full-fledged crown is formed;
- using articulating paper the doctor gives the crown an ideal shape.
