Figures 45-48After a fit check inmouth, the teethwere placed.Our task was to neutralize additional reddishgreyshade using the complementary colors theory.We were worried when we started this case. Theveneer thickness was only .7mm and the bright redcolor of the tooth core was frightening. However,the effect turned out to be very esthetic. By placingveneer on the abutment, we completely blockedundesired color. It is vital to remember, that if youdon't want to get undesired side effects, you need touse transparent luting material.As a result of this work, two centralincisors were recovered, using the technique ofcomplementary colors. At the same time thelateral incisor needed only slight reposition andmorphology enhancement, and was handled usingcommon method.It should be emphasized that there is nomutual mismatch between these restorations. Beingmade with use of fundamentally different methods,they look absolutely natural and restored theimpressive smile of the patient.About the Author:Nikonenko is a master dental technician atPhoenix Dental Labs in Moscow, Russia.Editor’s Note: This article was first published inLAB, Russia.45. 46.47. 48.QUIZ:Receive .5 point documented scientific credit for passing a quiz about this article.
