Stereolito grafija (SLA) se rabi kao pomagalo pri rekonstrukciji teških defekata nakon operacije tumora, traume, malformacije lubanje te za planiranje implantoloških zahvata u bolesnika nakon mandibulne rekonstrukcije. U 16 bolesnika provedeno je CT snimanje rekonstruirane donje čeljusti s debljinom sloja od 1 mm ili tehnikom spiralne CT, kompjutorska obrada podataka slojevnih snimaka i konstrukcija stereolito grafsko ga modela mandibule. Zatim je po modelu stvorena individualna šablona za umetanje BONE—LOCK implantata. Nakon oseointegracije konstruirana je suprakonstrukcija i završen protetski tretman s odličnim funkcijskim i estetskim rezultatima. Točnost dimenzija stereolitografskih modela izrazito je visoka, s odstupanjem od ±0,5 mm. Metoda se pokazala veoma pouzdana u teškim implantološkim slučajevima nakon koštane rekonstrukcije donje čeljusti.
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.
