contrasted view of multiple diastemata

Single shade for diastema closure

The restoration of anterior teeth is one of the biggest challenges for a dentist, because of the difficulties in color matching, and in recreating natural internal structure of the tooth. Small median diastemata and small spaces are the most difficult ones to restore, so special, dedicated tools, such as the Unica matrix (Polydentia powered by Styleitaliano) are needed to make the process easy.

Isolation with rubber dam is very important in order to provide a clean, clear and dry environment.

simultaneous unica matrices for emergence profile and diastema closure

Fig.7

Two Unica matrices were used to give an anatomical contour and emergence profile, which is the main challenge when closing diastemata.

The restoration was completed by applying a single, universal, composite shade.

The Unica matrix was also used to get a good emergence profile while close the space between the central and lateral. Liquid dam is useful to secure the matrix and to prevent its deformation.

Conclusions

When dealing with aesthetic restorations, an optimal reconstruction of the tooth profile is paramount. In case of diastema closure, various tools and procedures can help the clinician to correctly restore the emergence profile; among these, the new Unica anterior matrix stands out because of its simplicity and versatility, allowing to quickly and easily restore both cervical and interproximal profiles at the same time, strongly reducing the chair-side time, and bringing aesthetic restorations within everyone’s reach.
