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.
