Instructions to use Wagotrix Sectional Matrix System

  1. Placement of Pre-Wedge. After rubber dam placement and preparation, select appropriate size wedge and place interproximally on either buccal or lingual surface. Pre-wedging allows for pre-separation and makes matrix application easier.(Figure 1)

  2. Placement of Matrix. Select matrix based on the approximate occlusogingival height. Place prongs of Pin-Holder through corresponding holes in the matrix with the gold side visible to easily disengage the instrument once the matrix is in place. Slightly withdraw pre-wedge before inserting matrix and then reinsert wedge once matrix is placed.
    If you prefer to place matrix before wedge, place a finger at the occlusal aspect of the matrix to hold it in place & prevent it from dislodging, or use Pin-Holder to secure matrix, proceed with wedge placement. (Figure 2).

  3. Placement of Wagotrix™ Ring. Use the ring forceps to grasp and slightly expand the ring. Carefully place the ring as low as possible with the tines of the ring close to the gingival margin and straddling the wedge(s). (Figure 4)

    Mesial & Distal Ring Placement: The ring may be placed mesially and/or distally for better access such as the case with MOD restoration. (Figure 8)

  4. Perform Restoration: Proceed to fll entire cavity preparation with Wagofl™ Zirconium Composite, or desired composite material.
  5. Wagotrix™ Removal: Remove ring using Ring Forceps, remove wedge(s) using Pin-Holder, separate matrix from composite using a thin bladed instrument by pushing the instrument into the embrasure. Fold matrix wings backwards and cure composite again from buccal and lingual surfaces. Remove matrix with Pin-Holder; grip one of the matrix holes with the Pin-Holder and gently wiggle the matrix out. (Figure 10).

    If needed, you may use another Pin-Holder on the “opposite” side of the matrix and move the matrix back and forth, or upward, until loose.
  6. Contour & Polish Final Restoration.
