An instrument for the clinical application of fillings for dental cavities comprises a matrix retainer and a proximal central matrix provided with a detachable element for ensuring that the tooth considered is in contact with the adjacent tooth after filling of the cavity. The detachable contact element is provided with an anchoring member and inserted in a cutout formed in the matrix. After setting of the filling material within the dental cavity, the detachable element remains incorporated in the material by means of the anchoring member.
