U.S., Jan. 28 -- ClinicalTrials.gov registry received information related to the study (NCT07370701) titled 'Passivity of Full-Arch Co-Cr Maxillary Prostheses Using IOS' on Jan. 13.

Brief Summary: Statement of the problem: Accurate digital scans of edentulous patients is challenging due to the absence of anatomic landmarks and geometric variations along the dental arch. Whether adding an auxiliary geometric device (AGD) will improve scanning is unclear.

Purpose: The aim of the study is to analyze the accuracy of complete-arch digital scans of completely edentulous arches by placing auxiliary geometric device.

Material and Methods: This in vivo study included patients who received complete arch screw-retained prostheses supported by 4 imp...
