3D Stereolithography Print (SLA) in Clinical Orthodontic and Dental Applications

The aim of our study was 3D objectification of stereolithography prepared printed models. Patients during clinical treatment were scanned by an optical scanner. Data from scanner were transferred to the STL files and then stereolithographic models were prepared. Method of optical triangulation, photogrammetric methods and mathematical model analysis were used for measurements. The surface profile was also evaluated. After three years, the quality of STL models was smooth and homogeneous and it was directly connected with the type and structure of filaments. Clinical applications demonstrated also treatment options for patients with nausea, rare diseases, or with small space between upper and lower jaw.
