case report

A young girl with two ceramic veneers in the laterals came to our attention to improve her aesthetics. We proposed to substitute the veneers with new composite ones. The creation of composite veneers not only satisfied the patient’s desire to know the final anatomy before the completion of the treatment but provided an easier solution to modify than using ceramic veneers. The following case study shows the step-by-step procedure of the composite veneer built up using Polydentia’s Unica anterior matrix.


1: Pre-operative view showing two ceramic veneers on laterals 12 and 22.


2: Isolation of the operatory field.


3: Old ceramic veneers have been removed first. Adjacent teeth have been protected using a metal matrix before proceeding to sandblasting the surfaces with aluminum oxide and water. Sandblasting allow us to eliminate some remains of the previous restoration and pave the way for the adhesive procedure.


4: Adhesive procedure: a universal system adhesive with a selective etching approach has been used to increase the bonding forces in the enamel.


5: Insertion of Unica anterior matrix.


6: Unica anterior matrix placed on the tooth. The contoured proximal walls of the matrix provide the anatomy and the emergency profile required for the restorations in the anterior region.

7: Fixing Unica anterior matrix using wooden wedges.


8: Composite was placed and smoothed with paintbrushes and spatulas.


9: After removing the matrix an optimal contour is obtained, only finishing and polishing procedure are required.


10: Composite has been covered with oxalate gel and polymerized for 20 seconds.


11: Finishing and polishing procedures are carried out with discs and burst.


12: The restoration after finishing and polishing.


When dealing with direct restorative procedures of the anterior teeth, one important aspect is the management of the cervical areas. Often, retraction with gingival retraction cords or a rubber dam will not allow to obtain a proper gingival profile.
The unique design of the Unica anterior powered by Style Italiano makes this matrix an essential and very efficient tool since it enables us to work both in the interproximal and cervical areas at the same time.
