Fabrication of Master Cast for Fixed Prosthodontics: Step by Step Procedural Videos
|9068||January 4, 2012||1|
This resource contains a set of instructional videos showing the process of fabricating a master cast for fixed prosthodontics. It is primarily intended for dental students to learn the laboratory components involved in full coverage crown restoration. Twelve short clip videos were produced and packaged together to depict the step-by-step sequence of master cast fabrication. The resource has an interface that allows student to watch the videos in full control. They can pause, forward and playback to watch the segment of the video clip. The interface also provided students the ability to read and scroll the narrative description of procedure while watching each of the video clips.

Effectiveness and Significance
After taking the final impression for fixed prosthodontics, dental students should be able to pour up their impressions and fabricate master cast to complete the process of full coverage crown treatment. These procedures require knowledge of the steps and the skill to perform the procedures. This resource which contains several short videos has been very helpful for dental faculty in aid of teaching. They use the resource to demonstrate the details of the steps while allowing the students to watch multiple times.
The resource helps standardize the approach and technique and reduces the confusion that students may experience due to varying techniques that may be shown by multiple dental faculty in the large class setting. The resource also serves as an advance organizer that provides a good overview to students, thus shortening the time required to explain the content of the material to new students. The resource also serves as a reference for students to review procedures when needed.
Special Implementation Guidelines or Requirements
This resource serves as an advance organizer prior to lecture. It is deployed online via course management tool (WebVista and Moodle). Students are given access to the resource 1 week before the scheduled time of the lecture. They are asked to watch the videos 3 times. During the first viewing time, the goal is to get an overall sense of what the content is all about. In the second viewing time, students are required to list on a paper the chronological step by step procedure. The third viewing time, students are asked to generate questions that will be brought up during the lecture period. These repeated viewing times have provided significant background information for students that made lecture session very productive and meaningful.
Faculty involvement in teaching saves significant amount of time explaining and elaborating the steps of the procedure during lecture. Contact time is spent more on productive discussions (reducing discussions that are otherwise shown in the resource). Faculty saves time also in setting up for demonstration. The resource instead substitutes for the live demonstration.
This resource can be utilized with a minimum faculty involvement.
