[Our experience with the preparation of fixed segmented bridges with nonrigid extracoronally placed connectors. Case series].

AIMS
For the replacement of dental deficiencies when the difference in axis between the future abutment teeth is considerable and preparation of a fixed bridge-prosthesis is planned without the sacrifice of too much extra dental tissue, one possibility is to prepare fixed separated dentures with nonrigid connectors.


METHODS
From 1999 to 2007, we prepared such dentures, initially using intracoronal retainers in accordance with the literature, after that we positioned the retainers extracoronally whenever this was possible.


RESULTS
In 35 cases we prepared multi-unit fixed prostheses with a total of 43 retainers. These segmented prostheses could be fixed rigidly after cementation. All of them remain in place without any complaint.


CONCLUSION
Fixed dentures prepared with extracoronal retainers proved safe and esthetic and extra dental tissue is not sacrificed.
