DATA & FILE OVERVIEW
---------------------
Directory of Files:
   A. Filename:        precision study
      Short description:        This is for the original study: Reproducibility of complete-arch implant scanning: effect of scan bodies. There are raw 3D models of optical scanning, processed models, measurements using Geomagic software and CMM. Numbers and SPSS tables recorded all raw data. And some tables and figures after analyzation. 
        
   B. Filename:        calibration study
      Short description: This is for the original study: A novel auxiliary device to improve the accuracy of intraoral implant scanning in complete edentulous arch. There are CAD drawings, raw 3D models of optical scanning, processed models, measurements using Geomagic software and CMM. Numbers and SPSS tables recorded all raw data. And some tables and figures after analyzation.

C. Filename: alignment study
Short description: This is for the original study: Effect of scan body geometry on accuracy of the computer-aided design in digital implant workflow. There are raw 3D models of optical scanning, processed models, measurements using Geomagic software and CMM. Numbers and SPSS tables recorded all raw data. And endnote files containing related literatures, 
some tables and figures after analyzation.

D Filename: auxiliary study
