REIS, André Figueiredo; KUMAGAI, Rose Yakushijin    ALVES, Paula Maria Mendes. The use of a bulk-fill composite and a new sectional matrix system for optimization for Class II restorations. Rev. Assoc. Paul. Cir. Dent. []. 2016, 70, 3, pp. 250-254. ISSN 0004-5276.

New technologies associated with new materials have been introduced to facilitate the daily clinical procedures, reducing the number of steps, thus reducing the chance of mistakes and chair time for clinical procedures. Male patient, 38 years old, had a deficient OD class II restoration in the lower left first molar. Clinical examination, x-ray and color selection were performed. Using rubber dam isolation, the old restoration and caries were removed. For the new restoration a sectional matrix system and a low-stress flowable bulk-fill composite were used, followed by a conventional nanohybrid composite as recommended. It can be seen that the bulk-fill technique is quite simple compared to the traditional incremental technique and combined with the system of sectional matrix system further optimize the restorative procedures.
