Online Course Demo: Crown Preparation

Goals and objectives
Despite enthusiasm for the educational potential of the World Wide Web, few dental educators use the new opportunities offered by this medium beyond the presentation of textual information. Based on this observation, we have decided to design our own interactive Web-based 3D crown preparation course. The course objective is to provide dental students with fundamental didactic and technical knowledge to begin preclinical skill development for full crown preparations. The course incorporates a variety of interactive features including images which allow students to examine the dimensions and contours of the burs in comparison to the dimensions and the shape of the crown preparation. QuickDraw 3D allows the direct manipulation of 3D graphical models by the users.

In the past Temple University School of Dentistry (TUSoD) integrated several Web-based resources into the school’s intranet to enhance the opportunities for teaching and patient treatment. The crown preparation course was developed by Ronald Kaiser during an internship at the Department of Dental Informatics in connection with the Department of Restorative Dentistry from September 1999 to February 2000. Temple has decided not to continued to offer the program. Thus, the crown preparation course was moved to the University of Pittsburgh School of Dental Medicine.

The course was presented at the 2000 American Medical Informatics Association’s Annual Symposium (AMIA):
Spallek, H, Kaiser, R, Boberick, K, Boston, D, Schleyer, T: Web-based 3D online crown preparation course for dental students. AMIA Fall Symposium, Los Angeles, CA, November 4-8, 2000.
It was submitted to the 2001 Instructional Computing in Dentistry competition organized by the American Dental Education Association and won an “Honorable Mention.” Recently, the course has successfully passed the peer review process and has been officially indexed, formatted, and published at AAMC’s MedEdPORTAL, a  free peer-reviewed publication service and repository for medical and oral health teaching materials, assessment tools, and faculty development resources:
