Evaluation of Perception on Intra-Oral Scanning and Alginate Impression among Orthodontic Patients in Chennai

Abstract

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.
