mouth in particular are governed by the golden ratio
linking the principles of symmetry and asymmetry.
The golden ratio, which has often been called the
divine proportion, is a mathematical constant that
can be derived from, and be used in, dental aesthetics.
For example, this constant phi (oI = 1,6180339887...)
can manifest itself in the relationship between the
length and the width of the tooth. Although the
golden ratio is an oft-cited topic in dental aesthetics,
the attendees in Belek were once again fascinated by
this irrational mathematical ratio that is considered
particularly harmonious and beautiful – whether in
architecture or in present-day dentistry.
Nerve injury and bone augmentation
From aesthetics, the focus returned to the depth of
the maxillary sinus – which is the realm of Prof Joa -
chim E. Zöller. In his second presentation he illustrated
the importance of a correct diagnosis before any
implantological procedure in order to prevent nerve
injury and enumerated the therapeutic guidelines to
be applied. A typical nerve injury he cited was the
damage sometimes caused by a casual injection.
Experience has shown that the inferior alveolar nerve
hardly ever ruptures – not even in the event of a
mandibular fracture. On the other hand, the nerve is
highly susceptible to damage by pointed or sharp
instruments, being more sensitive to pressure than to
tension. His advice was to “keep the tweezers away”.
Zöller also discussed augmentation and the associated
risks. He made clear that the use of autologous
bone material was the most valuable procedure from
a biological point of view. Bone replacement material
should be reserved for sinus lift procedures or collateral
augmentation of defects.
