J. Hoffmann et al., ORBITAL RECONSTRUCTION WITH INDIVIDUALLY COPY-MILLED CERAMIC IMPLANTS, Plastic and reconstructive surgery, 101(3), 1998, pp. 604-612
Diagnostic advances such as computed tomography and new surgical techn
iques hare dramatically improved both the functional and aesthetic out
come of orbital reconstructions. Taking a further approach, we designe
d ceramic implants (Bioverit) on the basis of stereolithographic model
s. After copy milling a resin template with a commercially available d
ental unit (Celay), the prefabricated implants were inserted for recon
struction of the lamina papyracea (n = 1), zygomatic complex (n = 2),
infraorbital floor (n = 5), and rim (n = 3). Intraoperatively, only sl
ight modifications of the implants had to be performed. The results we
re encouraging, as all cases showed a good aesthetic and functional po
stoperative outcome. Preoperative evaluation of the osseous defect and
prefabrication of the required implant reduced operating time and pat
ient morbidity significantly.
