Artificial Intelligence Supported Intraoral Scanning.
Condition: Impression Technic, Dental
Study type: Interventional

Summary: 
      Digitization (automation) of production stages with Computer-Aided Design and Computer-Aided
      Manufacturing (CAD/CAM) technologies has led to a digital revolution in dentistry, as in many
      other fields of the industry. In current dentistry, the digitalization process can be defined
      as direct and indirect workflow. The clinical reliability and success of the indirect digital
      workflow made possible by these technologies have been proven by scientific studies. With the
      development of intraoral scanners (IOS), a virtual model is obtained by direct
      digitalization. This method eliminated the conventıonale impression and dental cast model
      steps required for indirect digitalization. Intraoral scanners are used as an alternative to
      convantıonal impressions in single and short edentulous cases. It has already been emphasized
      that direct digitalization is a reliable alternative to the conventional impression method,
      as the clinical applicability, accuracy, and precision of the manufactured restorations have
      been scientifically verified. Therefore, the clinical use of direct digitalization is
      increasing (exponentially) day by day, and new upgraded versions of software, along with
      various modifications for the hardware equipment, are being developed. Integrating artificial
      intelligence (AI) supported software into the intraoral scanning process can be seen as the
      beginning of a new era for direct digitalization. Therefore the aim of this study is to
      evaluate the effect of artificial intelligence on the scanning time, the amount of data
      collected, and the image accuracy obtained.
    

Detailed description: 
      It was planned intraoral scanning (3Shape TRIOS A/S, Copenhagen, Denmark) of the
      participants' mandible (n=21) with artificial intelligence (AI on) and without artificial
      intelligence (AI off). Reference equilateral triangles for scanning were digitally designed
      and produced with a 3D printer. Then these triangles bonded to the buccal surfaces of #34,
      #44, and the lingual surfaces of #36#46 teeth. The lower jaw of each participant was scanned
      by the same operator, in line with the recommended scanning protocol. Furthermore, scanning
      was performed randomly, with AI on and off.

      The IOS software automatically recorded the data required for quantitative comparing the
      scanning time and the obtained images (TRIOS Scanning Version 1.18.310, 3Shape A/S). In order
      to compare the scanning effectiveness between the methods, the area data of the digital
      images of the triangular objects obtained during both scans were calculated in a computer
      environment with reverse engineering software (Geomagic design X version 2016.1.0, 3D Systems
      Inc. Rock Hill, SC).
