The patient, a 25 years old male came to our attention presenting a dentoalveolar trauma with fracture of incisor 21 and partial chipping of incisal edge on 11. Since no pulp exposure was observed, we decided to proceed to the immediate dentinal sealing followed by the direct composite reconstruction of the tooth anatomy.
The following images show the step-by-step restorative procedure using the Unica anterior matrix.
1: Pre-operatory view evidencing a dentoalveolar trauma with a complex crown fracture without pulpal exposure on incisor 21 and partial chipping of the incisal edge on 11.
2: Isolation of the operatory field using a rubber dam before proceeding with the elimination of enamel without sustenance and preparation of the vestibular bevel.
3: Installation of Unica anterior; in the present case the contoured shape of Unica allowed a stable placement, even in absence of contact points. For this reason, we decided not to hold Unica in place by wedges nor by the light-curing flowable myCustom Resin (Polydentia).
4: Immediate dentinal sealing in dentine with Scotchbond Universal (3M).
5: Selective enamel etching with orthophosphoric acid.
6: Adhesive procedure: application of a universal adhesive system (Scotchbond Universal 3M).
7: Reconstruction of the proximal profiles with Filtek Z350 Body A2. Another advantage of the contoured shape of the Unica anterior is the possibility to visualize the final contour of the tooth before proceeding with the restoration.
8: Reconstruction of coronary fragment with Filtek Z350 Body A2 with the help of Compobrush (SmileLine).
9: Reconstruction of coronary fragment with Filtek Z350 Body A2 with the help of Compobrush (SmileLine); Before proceeding with the final shaping and polishing, the composite was light cured and the matrix removed.
10: The clinical situation after contouring the emergence profile and proximal walls. This image shows the tooth texture sketched on the composite surface.
11: The final anatomy of incisor 21 before polishing.
12: Final polishing with Soflex diamond spiral 3M.
13: Immediate post-operative situation.
Unica anterior is an indispensable tool for the reconstruction of anterior teeth that have suffered dentoalveolar trauma, because its design and thickness it allows to safely return the contour, emergency profile and contact relation of the anterior teeth, reducing the clinical time in retouching later. Unica anterior also protecting the neighbouring teeth during the procedure. Unica anterior facilitates my daily clinical work.
