The experience of using the developed matrix systems for individual restoration of class II cavities according to Black
To propose a unified system for ensuring isolation of the working field and high - quality restoration of the contact point in dentistry. Materials and methods. The existing types of matrix systems offered today in the global dental market are studied. The design of a clamp for a cofferdam has been developed, which allows it to be used to fix the matrix. It provides high - quality restoration of the contact point. Used a3D printer Formlabs Form 2, Autodesk Maya, Fusion 360 - programs for creating three - dimensional graphics; burnout material for 3D printing of injection molds Formlabs Castable Vax; metal alloys, polyetheretherketone, liquid rubber dam.Conclusion. A unified system of isolation and restoration of a contact point in dentistry has been created. It provides high - quality isolation of the working field, and also solves the difficult task of filling cavities of class II according to Black. The described technique allows you to individually approach each patient. Successfully used in clinical practice.
