Background: Most of the treatment modalities in dentistry are based on obtaining study models. The study

models are of two types, namely, conventional study models made of gypsum products and digital models

Aim: To evaluate patient’s perception on intra-oral scanning and alginate impression in Chennai population.

Methodology: 20 subjects were selected from the Department of Orthodontics, Saveetha Dental College

and Hospital, Chennai. Conventional impression was made using alginate and intra-oral scanning was done

for the same patient after 5 days. The patients were asked to fill a questionnaire comprising of 12 questions.

Results: Majority of the participants reported that alginate impression had more gag reflex and made the

mouth dry. Participants preferred alginate impressions in terms of maximum mouth opening. The overall

discomfort was equal for both techniques. Intra-oral scanning consumed more time than alginate impressions.

Thus the overall preference rate was equal for both intra-oral scan and alginate impression.

Conclusion: Orthodontic patients in Chennai reported equal preference for intra-oral scan and alginate

impression.
