Dental Tribune Middle East & Africa Edition | 2/2016 endo tribune 3 Fig.22 Fig.26 Fig.24 Fig.23 Fig.25 After the preparation phase of the anatomical pin and coronal portion of the core with compound resin, preparation for adhesive cementa- tion to the remaining tooth began (Fig. 15). Acid etching of the pin was performed for 30 seconds, and then it was washed and dried. The silane was then applied (Silano) for 20 sec- onds,aswellastheadhesive(Fusion- Duralink) with subsequent photoac- tivationfor20seconds(Figs.16–18). After the anatomical pin had been prepared, acid etching was per- formed on the remaining tooth for 20seconds,followedbywashingand drying it lightly to leave the dentine moist (Fig. 19). The dentine primer and the adhesive (Fusion-Duralink system) were applied and then pho- toactivatedfor20seconds(Fig.20). The cementation was done with auto-polymerisable resin cement, waiting a period of five minutes for the cement to chemically set (Figs. 21 & 22). Once the cementation of the anatomical pin was finished, the adhesive was applied to the coronal portion and photoactivated for 20 seconds, and the compound resin was applied in incremental portions forcreationofthecore(Figs.23&24). In order to complete the restorative process, the prosthetic preparation of the core was performed for future seating of a full ceramic crown (Fig. 25). Conclusion The anatomical pin constituted a clinical alternative for coronal and radicular reconstruction of endo- dontically treated teeth with signifi- cant destruction of dentine. In addi- tion to rehabilitating the tooth, this clinical approach promotes a more balanced distribution of mastica- tory forces without com - promis- ing the remaining tooth structure, minimizing the risk of radicular fracture. Moreover, this restorative alternative provides the possibility of an aesthetic result with the use of ametal-freefullcrown.
