Dr. Anne-Katrin Lührs, University of Hannover/Germany, demonstrates the preparation of a front tooth for the restoration with a veneer on an anatomical model. Step by step she explains her preparation procedure which is the basis for an aesthetically and functionally satisfying result of a veneer restoration.

To begin with, depth orientation grooves are placed at about 1–1.5 mm depth. Dr. Lührs starts in the incisal area, followed by the reduction of the incisal edge according to the orientation grooves. Next, depth orientation grooves are placed in the cervical region, which are extended to the entire labial surface following the natural tooth contour.

Now the complete labial surface is adjusted to the depth of the orientation grooves, and a wrap-around preparation conducted. In the palatal area a chamfer is prepared. Finally, sharp edges and corners are removed and surfaces and transitions are smoothened. For the impression, Dr. Lührs recommends the insertion of little matrix bands in the interdental areas.
