Introduction: The dental industry has seen a significant push toward digitization in recent years; as a result, digital approaches utilizing intraoral scanner devices, which enable data entry into computers without the need for physical contact, are replacing traditional 2D models. Traditionally, clinicians have planned cases using 2D images.
Aim of the Study: To evaluate the effectiveness and accuracy of using intraoral scanner (Medit i700) to register the anatomy of normal auricular morphology using 3D software assessing the reliability of different scanning protocols.
Methodology: Ten auricles were scanned using Proface 3D Imaging (reference group) and using Medit i700 in three different techniques (without markers, with markers and with spray opaquer using Geomagic Control X.
Results: Using (Medit i700), there was a statistical significance difference in total deviation (RMS) as well as point deviation in the seven selected deviation points using no marker, markers and spray technology on being compared to reference model. However, the clinical significance of the total deviation as well as for the point deviation for the three technologies showed between mild to moderate clinical deviation to be SD
