The Helmut Zepf matrix retainer, referenced under code 19.062.00, is a manual instrument designed by Helmut Zepf Medizintechnik GmbH. It is a metallic matrix retainer made of medical-grade stainless steel, intended for restorative dentistry.

This instrument is indicated for all dental restoration procedures requiring the use of a matrix for formwork. Its primary role is to stabilize the metallic matrix around the dental crown, particularly during the treatment of proximal cavities (Class II). It allows the practitioner to adjust the tension of the band to ensure optimal sealing at the gingival level and restore the natural anatomy of the tooth, thus facilitating the creation of a functional contact point with adjacent teeth.
