Effect of coded healing abutment height and position on the trueness of digital intraoral implant scans.

Statement Of Problem: Information regarding the effect of the height and position of a coded healing abutment (CHA) on the trueness of intraoral digital scans is lacking.

Purpose: The purpose of this in vitro study was to investigate the effect of the height and position of a scannable CHA on the trueness (distance and angular deviations) of intraoral digital scans.

Material And Methods: Scannable CHAs (BellaTek Encode Impression system; Zimmer Biomet Dental) were used in 2 different height pairs (3 mm and 8 mm) on 2 implants at mandibular left second and first molar positions.
