Omnichroma Flow offers a quick solution in 20 minutes


A 56-year-old patient complains of a chipped upper right central incisor. Tooth # 8 had a chip on the incisal edge and was very sharp (Fig. 1). The patient also did not like the appearance of the chipped tooth. The patient was told that when the front teeth wear down, the remaining enamel is thin, brittle, and unsupported. This way, if the restoration flakes off again, the patient will not be too surprised. It also helps to encourage the patient not to chew hard food, nail biting, or other deleterious habits that can cause the restoration to fail. The material selected for this procedure was OMNICHROMA Flow and complementary OMNICHROMA BLOCKER Flow (Tokuyama Dental). This material will take on the shade of the surrounding enamel and works extremely well for small restorations, such as this clinical case.

It was not necessary to take a shade, because OMNICHROMA Flow automatically matches the color of the tooth. Anesthetic was not used for this procedure, as there was no cavity and the restoration was mostly enamel. The tooth was bevelled with a diamond bur on all edges to help melt the restoration and have better adhesion to the enamel. Both the enamel edges and the restoration surface were acid etched (35% phosphoric acid). The tooth was then thoroughly rinsed with water and air dried. Then a bonding agent (Bond Force, Tokuyama Dental) was applied in two applications over the restoration surface and slightly beyond the margins. The tooth was then light-cured.

To avoid the show-thru of the restoration, OMNICHROMA BLOCKER Flow was placed on the lingual surface in a thin layer (0.5 mm). A sealant matrix was made over the lingual-incisor area to create a lingual shelf to precisely hold OMNICHROMA BLOCKER Flow in place until it could be light-cured (Fig. 2, 3).
