Shade selection
The tooth shade is determined with the help of a shade guide according to the
A-D or PE shade system of Ivoclar Vivadent.
Anterior tooth selection
If possible, the anterior teeth should be selected directly with the patient according to
anatomical and mimic characteristics. The anterior teeth are categorized into triangular, oval
and square shapes. However, it should be noted that each mould has its own distinctive character.
* Triangular tooth moulds
This group is characterized by teeth having a crown which tapers towards the cervical
ridge. The vertical curvature is moderate.
* Oval tooth moulds
The teeth of this category have a pronounced curvature. The labial curvature is particularly marked.
* Square tooth moulds
With this angular shape, the central incisor is dominant. The vertical labial curvature is moderate.
Chairside
The facial meter allows fast and targeted selection of the appropriate anterior tooth size.
The sample teeth of the SR Vivodent S PE and SR Vivodent S DCL shade guide feature
the same layering structure and material as the marketed original teeth. Shade deviations
will be consequently reduced to a minimum. The shade selection with the patient should
be carried out under defined light conditions (5,500 K colour temperature) or during
daylight (preferably light from the north).
Step 1: Measure the interalar width of the nose with the facial meter and select the
appropriate tooth size S/M/L.
Step 2: Select between triangular, oval and square tooth shapes within this size range.
The papillameter is the ideal device for the definition of the length of the upper lip and the
lip closure line. Especially for the length of the anterior teeth, the lip closure line provides one
of the most important pieces of information.
Labside
The following reference points are determined with the help of a model analysis:
a) Position of the canines
Identify the first large pair of palatine rugae; the midpoint of the labial surface of the
upper canines is aligned at a distance of approx. 9 mm.
b) Contact point of the central incisors
The labial surface of the central incisors is aligned at a distance of approx. 7 mm from the
centre of the papilla incisiva.
The length of the arch measured across these three points can be used as a reference to
select a set of anterior teeth with an appropriate width from the tooth mould chart.
