Basic information on the SURGICAL PROCEDURE - Straumann

3. treatment PLanninG
careful treatment planning is of the utmost importance in implant-borne restorations.
a comprehensive pre-implant diagnosis, evaluation and plan are required in all
cases. these provide <strong>information</strong> for the implantation itself as well as for designing
the superstructure. close communication between the patient, dentist and dental
technician forms the basis of careful case planning.
Procedure with crown and bridge restorations
to establish the topographical situation, the axial orientation and the choice of implants,
in difficult situations we recommend making a wax-up/set-up on the previously
prepared study cast and then defining the type of superstructure. the implant abutments
should in principle always be loaded axially. ideally, the long axis of the implant
is aligned with the cusps of the opposing tooth. extreme cusp formation should be
avoided as this can lead to unphysiological loading.
the ideal reconstructive position and esthetic result can be established using the
wax-up/set-up and can later be used as the basis for a custom-made X-ray or drill
template and for a temporary restoration*.
The implant is the apical extension of the prosthetic-driven restoration and
therefore needs a prosthesis-orientated implant position.
