Impressions obtained before procedure, after cavity preparation, at baseline, three and five years will be directly scanned using 3D laser scanning device (GC Aadva Lab scan). After direct impression scanning, a gypsum cast (GC Fujirock EP OptiXscan) will be also made (baseline, three and five years). These models will be scanned for wear analysis with the GC Aadva software in order to compare two different evaluation methods.
