Justesse et précision des modèles de travail issus de l'empreinte optique

Abstract : Evolution of CAD/CAM permitted to develop new kind of models. Purpose: Quantify dimensional variations between different types of models: conventional method and digital method, and we compared trueness and precision. Material and method: We used 20 polyacrylic resin reference models and measured with a reference scanner. A conventional impression was made on each model and poured with dental stone. And a digital impression was made and a new model was designed by Rapid Prototyping. Results: Conventional method showed a trueness of 0,009 ± 0,082 mm but these results are not reproductible. Models fabricated by digital technic showed a trueness of 0,016 ± 0,105 mm with a reproductibility of results. Conclusion: Full-arch models obtained by digital method had a better precision. They can’t be used for a prosthetic treatment but can be done in dentofacial orthopedics.
