involved in the preparation. It is necessary to have the
matching virtual models - a fundamental prerequisite to
obtain definitive prosthetics that have the same shape as

Once the imprint phase is completed, we will rely on the
software for the design of the definitive teeth. To begin
with you need to draw the “Line Base” on the soft tissue
profile, highlighting the area within which the software
will detect and create a prosthetic crown with the correct
emergence profile able to support the papillae and the gin-
gival parabola previously conditioned.
Subsequently, the “Baseline” will have to be drawn for
each prepared tooth, highlighting the end of preparation.
