previously by conventional impression materials like alginate, agar, elastomeric impression materials, due
to its drawbacks like gagging, unpleasant taste etc. newer methods like digital impressions and digital
scanners had evolved. Digital scanners include a computer display and a hand held wand with a camera to
capture the intraoral images in three dimensions. Digital impressions are more accurate, time saving and
