Single shade in anterior veneers
For the veneering of anterior teeth which is mainly a big challenge for the dentists we have 2 choices – direct and indirect approach. Every dentist knows his ability and can choose one of these techniques. But it is important to do it with a minimally invasive procedure. If we want to use a direct approach we need to know very well the anatomy and the color. Today we have a new material on the market (Brilliant Ever glow, Coltene) which will help every dentist to create a very nice restoration using only one shade.
In this article we will discuss how quick and in a predictable way how to have a nice direct veneer with an easily polishable composite material.
Fig 1: Before restoration
Fig 2: We started to check color with VITA shade guide. The color of the teeth was whiter than B1 in the classical Vita Shade Guide
Fig 3: To make sure that we choose the right color we always can use the button try technique. We put 1.5 mm thicness of composite on the tooth and check the color with a Polarizer filter (Smilelite)
Fig 4: Its mandatory to use rubberdam for all adhesive procedures.
Fig 5: With the coarse discs we created a very small bevel and rounded all sharp edges
Fig 6: In this case we dont need to prepare the tooth. We wanted just to clear the surface of the enamel and remove aprismatic enamel for better adhesion
Fig 7: After sandblasting with 27 micron aliminium oxide sand. (Aquacut or Rondoflex)
Fig 8: First we have to isolate adjacent teeth with teflon tape than selective etching Fig Fig: Technique is used on the enamel for 30 seconds.
Fig 9: The self etching One Coat Universal Adhesive (Coltene) was applied over the enamel. The adhesive excess was removed using aspiration and a blow of air. When the adhesive is not moving anymore under the pressure of the air, then we know that the thickness is close to the optimal. Light curing will be minimum 10-20 seconds
FIg 10: We started by appying the first layer of the new submicron hybrid composite (Brilliant Everglow)
Fig 11: All tooth was restored with one BL shade and For the smoothing of the surface we use always brushes – Compo Brush (Smile Line)
Fig 12: The final stage of our layering must always be air isolated with glycerine. Curing for 1 minute.
Fig 13: We need 3 main phases to obtain a good polishing: contouring, finishing and polishing. With coarse discs we start the contouring phase of our restoration.
Fig 14: For the finishing of the Cervical Part we used rubber abrasive cups.
Fig 15; For the finishing of the ambrasures we used rubber abrasive points.
Fig 16: To create the illusion of perykimata we always use diamond Perio bur from StyleItaliano Finishing Kit (Komet) at a very low speed without water irrigation.
FIg 17: Polishing is finished with a silicone abrasive wheel. (Diatech Polishers by Coltene)
