30 I I case report _ restoration of endodontically treated teeth the objective of re-establishing the coronal portion of the tooth. _Case report A young male patient came into the integrated dentistry clinic at Universidade Severino Sombra needing restorative treatment of tooth #21. In the clinical and radiographic examination, significant coronal destruction and satisfactory endodontic treatment were noted (Figs. 1–3). Restoration with an anatomical pin was proposed to the patient, in order to recover the function and aesthetics of the tooth and provide for future reha- bilitation of the tooth with a full ceramic crown. First, the decayed tissue was removed from the remaining tooth structure and the fibreglass pin was selected(Exacto#3,Angelus),aswellastheaccessory pins (Reforpin, Angelus; Fig. 4). The radicular conduit was isolated with mineral oil and the compound resin was applied (Fill Magic NT Premium, Vigodent/ COLTENE) over the remaining tooth (Figs. 5 & 6) with the aid of a #1/2 Suprafill spatula (SS White). After filling of the conduit with resin, the Exacto pin andthepre-silanisedaccessorypins(Silano,Angelus) were inserted with the application of an adhesive (Fusion-Duralink, Angelus; Figs. 7–9). Next, the initialphotoactivationwasconductedonthepinand resin for 20 seconds. Finally,thecoronalreconstructionwasperformed with the previously used compound resin in incre- mental portions and photoactivation was conducted (Figs. 10 & 11). A marking was made on the most incisal portion of the pins to guide the subsequent cropping of the pins (Fig. 12). The anatomical pin was then removed and the final photoactivation was performed for 40 seconds (Fig. 13). Soon after, the pin was adapted to the remaining coronal structure (Fig. 14). cosmeticdentistry 2_2015 Fig. 16 Fig. 17 Fig. 14 Fig. 15 Fig. 18 Fig. 19 Fig. 20
