What is the issue or problem addresses in your research?

Computer-aided design and computer-aided manufacturing (CAD-CAM) digital technologies have been utilized in dentistry for more than 40 years. Digital implant impressions offer advantages over conventional impressions including reduced risks of distortion during the laboratory phases, improved patient comfort and acceptance and improved efficiency. Although digital implant impressions have been well studied, little has been reported about the implant scan bodies themselves.

What methodology did you use in your research?

In this study, coded healing abutments were used in 2 different height pairs on both the implants. Each pair was scanned 10 times with one intraoral scanner by one operator as per the individual manufacturer’s protocol to generate a total of 20 intraoral scan files. A laboratory scanner was used to generate master STL files for each abutment pair. A software used for the best-fit alignment procedure of the STL files.

What are the purpose/rationale and implications of your research?

The purpose of this in vitro study is to investigate the effect of scannable abutment height on the implant position trueness in the scans.
