Accuracy, time efficiency and operator preference in edentulous arch scanning: a preliminary report (original) (raw)

Aim The present in vitro study evaluated the accuracy of intraoral scanners (IOS) in a completely edentulous arches and analyzed the influence of operator experience on accuracy, also time efficiency and operator’s difficulty perception related to IOS procedures. Materials and methods Twenty participants were enrolled for the digital scanning procedure of a maxillary edentulous metal model using an intraoral scanner, Aadva iOS100 (GC Corp., Tokyo, Japan). Participants were divided in two groups according to their experience in intraoral scanning procedures: Inexpert (InE group) without any experience in dental scanning (n=10) and Experts (E group) composed of operators with at least 3 year of scanning experience with IOS (n=5). Five IOS procedures were repeated for each operator and exported as a correspondent Stereolithography (STL) file. The same model was scanned with a laboratory scanner (LSS) (D1000 3 Shape Copenaghen Denmark), obtaining an STL file of the model which has been ...
