PURPOSE. The present study aims at researching the subjective satisfaction of patients who have experienced both conventional impression taking and digital impression taking to measure the possibility of wide clinical application of digital impression.
MATERIALS AND METHODS. The study surveyed 170 adult patients over the age of 20, between October 2015 and April 2016, who voluntarily consented to participation and who experienced both conventional impression and digital impression at five dental hospitals that use intraoral digital impression. A total of 128 surveys were used for data analysis, involving frequency analysis, multiple response frequency analysis, descriptive statistics, and contingency table analysis, with the significance level set at 0.05.
RESULTS. Responses on the reason for taking impressions using the digital method appeared in the order of `for implant treatment` (43.8%), `for crown treatment` (30.5%), and `for inlay treatment` (15.6%). Patients satisfaction was higher for digital impression taking than conventional impression taking (P<.05). As the preferred choice of impression, digital impression (60.2%) was higher than conventional impression (11.7%). Responses on the reason for choosing digital impression taking appeared in the order of `no vomiting reflex` (35.1%), `reliability of 3D digital scanning` (33.8%), and `short time` (33.8%).
CONCLUSION. The patients preferred digital impression taking to conventional impression taking in terms of satisfaction.
