Student Evaluation of CEREC Chairside CAD/CAM System
Objectives: Ceramic crown fabrication by dental Laboratory is a well-proven technique to fabricate crowns. Chairside CAD/CAM is a method to fabricate ceramic restorations in dental offices. In this study CEREC which is one of chairside CAD/CAM manufacturers was studied. Both techniques provide acceptable clinical outcomes, however clinicians need to be aware of advantages and disadvantages of CAD/CAM method.
The purpose of this project is to investigate advantages and disadvantages of using CEREC chairside CAD/CAM system
Methods: CEREC technique presented to second year dental students in lecture and complemented with video demonstrations. Students completed CEREC scans of mandibular first molar tooth preparations and designed a full-ceramic crown using CEREC software. A survey questionnaire was given to students with 1-10 Likert scale and open-ended questions. After completing the surveys, students put their surveys into a box anonymously. Descriptive statistics were used to assess students’ perceptions of various aspects of the CEREC software.
Results: 87 students responded to the survey. Descriptive statistics showed that ‘on average’ student assessments were positive regarding the CEREC software as shown by mean and median scores for each survey item. Features that were particularly liked in the CEREC system were magnification, single visit appointment, and no lab involvement. Features that were particularly not liked in the CEREC system were technique sensitivity, too many steps, non-streamline software.
Conclusions: CEREC chairside CAD/CAM favored by students, however the number of steps need to be reduced.
