Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to investigate the accuracy of complete-arch digital implant impression using newly designed scan bodies with extensional structure.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Fully edentulous patients with 2-6 dental implants are included in this study. For each patient, the follow three impressions are made: conventional splinted open-tray impression, digital impression using scan bodies without extensional structure, and digital impression using scan bodies with extensional structure. The accuracy of the three impressions is compared in an inspection software.
