Features: - Tor Vm sectional contoured matrices are intended to separate the approximate surfaces of neighboring teeth during the restoration of type II. - All matrices are volumetric, concave, and formed from special corrosion-resistant steel. - Thin matrices are convenient to use for the restoration of small defects, and thick ones are for the restoration of large carious cavities with destruction in the subgingival region. - Thick matrices keep the form well, which in some cases does not allow the use of wedges when restoring the gingival margin. - Hard matrices are easier to introduce; however, their adaptation to the formation of a contact point is difficult. - Uses: For separation of teeth surfaces during dental composite resin filling.
