ABSTRACT

Objectives: To investigate how dental hygienists who have never used a digital oral scanner perceive the impression acquisition and evidence needed for prosthesis planning by using a digital oral scanner. Methods: From July 1, 2017 to December 31, 2017, subjects from Daegu, Gyeongsangbuk-do, Korea, were selected. The purpose of the study was described to dental hygienists who had never used a digital intraoral scanner. Questionnaires were distributed to the students selected. Of the 137 questionnaires distributed, 93 were used in the analysis after excluding 44 completed questionnaires that had errors or missing answers. Results: Of the respondents, 33.7% (36/93) were aged ≥30 years, 68.8% graduated from a 3-year vocational college course, 33.5% were aged ≥33 years, and 61.3%. At present, our center has the largest number of clinics (92.5%). The difficulty of impression taking using the digital oral scanner significantly differed ( p <0.05) according to age and current occupation ( p <0.05). Impression taking using a digital oral scanner significantly affected the present workflow of dental hygienists and their interest in sharing information about future use of digital oral scanner ( p <0.01). Conclusions: If more routes are available to access digital intraoral scanners and more systems are developed for clinical use, the digital intraoral scanner could become digitized in the dental system; thereby, the existing impressions could be replaced with digitized impressions. With digital intraoral scanners, the expansion of the business of dental hygiene can be expected.
