Abstract: BACKGROUND: Digital impression technique or computer-aided impression (CAI) has been recently concluded as a clinically acceptable alternative to conventional impression method (CIM) in the fabrication of crowns, short fixed partial dentures (FPDs), and implant-supported crowns. OBJECTIVE: The purpose of this study was to investigate the patients’ opinion and subjective perception of two different ways of impression – digital and conventional. METHODS: A total of 45 patients were treated with CAI and CIM for the fabrication of tooth or implant-supported crowns. They fulfilled a questionnaire including 11 questions regarding the treatment time, gag reflex, discomfort related to manipulation, and other aspects of treatment. RESULTS: CAI was considered the preferential method for future treatment in 53% of patients, whereas 28.9% of the respondents preferred CIM. The preference for the impression method was influenced by the total time spent with the procedure, discomfort during manipulation with the tray or scanning head, size of the tray or scanning head, maximal opening discomfort, and (the tendency towards) gag reflex. CONCLUSION: CAI was considered a more comfortable and preferential method. Discomfort or difficulties during CAI negatively affected the patients’ attitude to CAI, whereas the difficulties associated with CIM did not have any influence on the preferred method.
