clinical case
This Patient attended wanting the spaces closed between her upper anterior teeth closed, as well as repairing the fractured incisal edges.
The following steps show the direct composite restoration using the Unica Proximal anterior matrix.

To maintain the ideal 80% height : width ratio of upper central incisors when closing spaces we need to lengthen (Magne 2003).

The cervical labio-palatal arch helps to secure the matrix between the papilla and the tooth sub-gingivally, in order to improve matrix stability after placement. A wedge can be used to secure the matrix but I find its not necessary when using these matrices.
The idea of using 2 back to back matrices when closing a space or even when placing 2 composite veneers, is simply to maintain the space for the adjacent tooth when restoring. It also acts like a wedge, which would normally compensate for the thickness of the matrix (30 microns). Therefore, the second matrix is acting as a wedge itself for separation.

conclusion
It is important to get the proximal area correct, not only for aesthetics, but for stability (prevent teeth drifting) and to protect the papilla from food trapping.
The use of the Unica allows the reproduction of the labial, palatal and proximal contours due to its pre-contoured shaped. Unlike posterior sectional matrices, they have longer cervical extensions for easy restoration of the cervical part of the proximal contour.
The Unica proximal cervical labio-palatal arch design also has the purpose of securing the matrix between the papilla and the tooth sub-gingivally. This makes the matrix very stable even without the use of a wedge.

Class II cavity direct composite restoration on a young permanent premolar – myClip 2.0 – Dr Marina Papachroni
For young patients rebuilding the anatomy in class II cavity restorations is a major issue but not making too many occlusal adjustments after finishing the layering procedures is one of the same importance aspects. The following images show the step-by-step treatment we performed for treating decay on the upper first premolar of a 15-year-old teenager. ...

Class II cavity direct restoration on young permanent molar with myQuickmat Forte – Dr Marina Papachroni
Class II (interproximal) decay involves the proximal surface of a posterior tooth and it is a common occurrence in many dental patients. One challenge for the clinician is to accurately recreate a physical contact to the adjacent tooth and, at the same time, to restore proper interproximal anatomic form. This case involves a teenager 16 years old with an interproximal lesion in his left lower molar (#36)....

The patient came for a consultation complaining of discomfort at tooth 36 when chewing. Molar 36 presented a very old composite restoration with initial disto-occlusal infiltration. We decided to carry out an OD restoration that also involved the buccal surface in order to replace the filling with a new aesthetic restoration. In this clinical case, we illustrate the procedure for the step-by-step restoration of tooth 36 using the Polydentia QuickmatFIT Molar sectional matrix in combination with the myQuickmat Forte sectional matrix ring....
