FenderMate kits consist of pre-curved plastic wedges with a built-in matrix. Offers a fast, safe, and predictable means of establishing a composite restoration.
Product Features:
- For small to medium Class II composite fillings.
- Designed to be inserted either buccally or lingually.
- During insertion, the wing presses the matrix firmly against the preparation, giving a tight seal at the cervical margin.
- The wing of the FenderMate separates the teeth thus compensating for the thickness of the matrix and retains the space created by the FenderWedge.
- Wedges also eliminate the need for a retention ring.
- Protects adjacent teeth from accidental damage and separates teeth for easier access.
- Inserts easily and stays in place during prep.
FenderMate Technique:
- Insert as a wedge with a sligthly downward and curved movement, like a "curved suture needle."
- Convex matrix shape with flexible wing exerts pressure for maintained separation and cervical marginal adaption. The correct position of the wing is under the level of preparation.
- Finally the pre-contoured contact point adjusts to the space and forms a correct contact.
FenderMate Kit Includes (pkg. of 72): 18 left regular (dark green), 18 left narrow (light green), 18 right regular (dark blue), & 18 right narrow (light blue).
All sizes sold individually (#44-14).
