Publication ID Published Volume
8376 February 17, 2011 7


This video illustrates a straightforward tooth preparation sequence for a 3-unit fixed partial denture where reduction accuracy and preparation draw are emphasized through the use of reduction guides and paralleling grooves. The demonstration is recorded on a typdont with Ivorine teeth using carbide and diamond burs. The video depicts the step by step preparation process taught by the Prosthodontics Department at The University of Texas Dental Branch at Houston to dental students, Prosthodontics residents and preceptors.

Innovations in fixed prosthodontic techniques: Tooth preparations for fixed partial dentures pose a challenge for dental students when trying to make their preparations draw. This video clearly presents an easy to follow technique that will help them solve this issue. Moreover it will objectively illustrate how much to reduce a tooth based on the restorative materials to be used. Teaching techniques: This video is an excellent communication tool that places tooth preparation techniques in the hands of the dental students and residents anytime they chose. It also maximizes the students’ comprehension and learning experience since they have infinite opportunities to review the material prior to and after class. It could be also used as a continuing clinical aid which the students can rely upon prior to treating their patients in clinic. It is, by far, a superior communication tool when compared to a static power point presentation since the students can observe a live demonstration of abutment preparation for a 3 unit fixed partial denture.
