Planning
General Information
Radiographic Evaluation
Dental x-rays
Dental x-rays are sufficient for the initial
assessment of bone supply with single
tooth gaps or small interdental gaps. The
periodontic situation of the remaining
dentition must be closely examined,
because the implant site may be colonized
by pathogenic organisms from
infected pockets.
Orthopantomograph
An OPG is a critical instrument for gathering
basic information. Additional data
required by the specific situation may be
obtained through dental x-rays, remote
x-ray side views, or computer-tomographic
scans (CT).
Remote x-ray side View
Use for large sagittal differences and
planned bone removal in the chin
region.
Computer-Tomographic Scan
The CT is an instrument to be used for
extensive radiological diagnostics. It
enables a 3-D evaluation of the site
from its anatomical structures and the
planning of augmentations. Indications
must be strictly adhered to because of
the level of radiation exposure involved.

Laboratory
Cast Analysis
It is essential to mount a diagnostic cast
in an adjustable articulator to assess jaw
relations. Specifically, a check should be
made whether a change of the
occlusal position is worthwhile or
required. If at all possible, it should be
done before the actual implant-supported
prosthetic treatment gets under way.
In any case, a change in occlusal height
must be preceded by treatment with a
long-term provisional.
Diagnostic Casts
The diagnostic casts must clearly show
not only the occlusal surfaces but also
the vestibular fold and retromolar areas
(see arrows).
Diagnostic casts for implant planning are
made of super-hard dental stone, just as
in perioprosthetics, and mounted on an
adjustable articulator with an arbitrary
face bow and centrics registration. The
centric registration must be freely
adjustable to enable the casts to be
mounted in correct axial alignment and
position.
The impression should reproduce the
soft tissue situation and any hard or soft
tissue deficits as far as the vestibular
fold, since it is here we detect the first
indications to incline the implant or the
necessity for bone augmentation. Just as
in perioprosthetics, the retromolar areas
must be reproduced to allow specification
of the dental arch and assessment
of the vertical space available (see
arrows).
Planning and implementation of periodontal
implant-supported rehabilitation
will be considerably simplified if templates
are used.
