Abstract
Stereolithography (SLA) is used for treatment planning in reconstruction of severe defects after tumor resection, trauma, malformations of the skull, and for planning of dental implantology
after mandibular reconstruction. In 16 patients, 1-mm CT scans and spiral CT scans of the reconstructed mandible were performed with image processing and stereolithography modeling of the mandible. Usual surgical drilling templates were manufactured for insertion o f endosseous BONE-LOCK dental implants. After osseous integration, the supraconstruction was designed and prosthetic treatment completed with excellent functional and esthetic results. The accuracy of stereolitho graphy models was very high, with a deviation of ± 0 .5 mm. The method was found very reliable in severe implantological cases after bone reconstruction of the mandible.
