3-D models for problem-based and case-based learning in Dentistry Dr. Yanqi Yang Dr. Susan Bridges Faculty of Dentistry, HKU email@example.com
“Electronic patient records” are the trend nowadays. Clinical treatment Clinical teaching
Plaster model (PM) •A special kind of clinical record for dentistry ---- models of the teeth. •Study models have long been an essential part of dental records.
Plaster model (PM) Virtual model (VM)•Traditional plaster casts are among the lastclinical record in the dental field to beconverted into digital media.•But virtual dental models are graduallybecoming more prevalent (Redmond, 2001).
Plaster model (PM) •Storage and retrieval •Transferability •Durability
Virtual model (VM)Advantages Simpler storage Reducing the risk of damage/disappearance/wrong location Simpler and more effective measuring Easy transferral to colleagues, other specialists, and even patients Other functions
Thus,in order to educate the modern dentalprofessional, the faculty decided that itwas useful to introduce e-models intothe Bachelor of Dental Surgery (BDS)curriculum.
Benefits to students gain experience with handling electronic data for dental recording keeping. have increased access through digital archiving on the learning management system.
Benefits to studentshave increased mobilityand flexibility by studyingthe models on computers.no need to borrow andcarry plaster casts.
Benefits to studentsEasier duplication means that individualstudents will each have access to a set ofe-models.
Benefits to studentsStudents will be able to perform model analysis ontheir own computers without staff needing to equipeach student with physical model analysis kits whichare problematic to provide.

The software of 3-D models isWhat have we done? uploaded to WebCT with approval by the 3-D models company for using the software in teaching.
What have we done?Key topic sessions for BDS students are held to introduce“Electronic Study Models --- a new mode of records” and totrain how to use the software.
What have we done?Software installed on the laptops for each PBL tutorialroom (to link with interactive white boards, IWBs)
What have we done?Traditional plaster casts for PBL and CBL are transferredto 3-D models and uploaded to WebCT in due time.
What have we done? Teaching Development Grant: Blended learning in Dentistry: 3-D resources for problem-based and case-based learning
What have we done? Initial student feedback and reasonable access rates indicate that the 3-D models have been generally well accepted by students.
Future workTo evaluate in more detail with respectto areas such as acceptability,appropriateness, accessibility,efficiency, and educational outcomes.
Future workTo use e-models in students‟assessment/examinations.
