Abstract :Objective: Over the last decades, techniques and materials have evolved with the improvement in digital technology. Computer-aided impressions have been transforming the dental implant field with these developments. The aim of this in vivo study was to compare the accuracy and time efficiency between two intraoral scanning systems in single tooth implant treatment. Material and Method: 10 patients with single tooth bone level implant insert ignore into journalissuearticles values(Straumann, Basel, Switzerland); received one conventional impression with polyvinyl siloxane and three scans with 2 different intra-oral scanners insert ignore into journalissuearticles values(CEREC AC Omnicam and Straumann CARES IOS);. The time required for the impressions was measured at this stage. The casts obtained from conventional impressions were scanned as the master model to evaluate accuracy. Digital impression files were analyzed using software insert ignore into journalissuearticles values(Geomagic Control);. Independent Samples Test was performed for trueness and precision. One-way ANOVA was executed for time efficiency. Least significant difference test for post hoc comparison was conducted insert ignore into journalissuearticles values(p<0.05);. Results: The differences between the two systems regarding trueness and precision were not statistically significant insert ignore into journalissuearticles values(P>0.05);, but a statistically significant difference was found in the time efficiency insert ignore into journalissuearticles values(P<0.05);. CEREC AC showed the lowest mean values in time measures. Conclusions: There was no difference regarding accuracy in the comparison between CEREC AC Omnicam and CARES. CEREC AC Omnicam was found to be superior in terms of time efficiency in comparison to CARES and conventional impressions.
