Individual CAD/CAM fabricated glass-bioceramic implants in reconstructive surgery of the bony orbital floor.
BACKGROUND
The aim of the study was to present a set of preliminary cases from an ongoing program of reconstructive procedures using a new technique in the treatment of severe enophthalmos and diplopia after the primary treatment of orbital floor fractures had rendered insufficient results.


METHODS
Glass-bioceramic implants were shaped from computed tomography coordinates with computer-assisted design and computer-assisted manufacturing. In this prefabrication process, the implants were milled individually out of a solid block of Bioverit II (3di Gmbh, Jena, Germany). The adequacy of this reconstruction for treating malfunction and aesthetic deficits was evaluated.


RESULTS
Eight patients with orbital floor fractures underwent successful surgery. The results were encouraging, with all patients showing a good functional and aesthetic outcome.


CONCLUSIONS
Computer-assisted design/computer-assisted manufacturing implants made of Bioverit II can be used for a very accurate and successful secondary reconstruction of the orbital floor. However, it addresses only a few aspects of the treatment of orbital floor fractures and should be considered as an equal alternative to other reconstruction methods.
