Fabrication of Provisional Restoration Using Direct Technique
|9055||December 6, 2011||1|
This lab manual is intended to provide dental students, dental assistants, and dental therapists with instructional guidance. This module will guide users through the steps of fabricating provisional crown restorations. The module will apply the principles of the direct fabrication of a provisional for a full coverage restoration. The module will guide users through the steps of the provisional fabrication procedure for tooth #30 full gold crown and an extension of this exercise is included regarding the fabrication of #9 porcelain fused to metal provisional restoration.

Effectiveness and Significance
This technique was implemented during the spring semester of 2010 in the University of Minnesota School of Dentistry Preclinical courses. Using this method, students learned to successfully fabricate provisional restorations for full coverage restorations.
Special Implementation Guidelines or Requirements
This module is used by dental students in a preclinical setting. It is intended to allow self-guided and self-paced instruction with or without the assistance of faculty. In order for this module to be employed, students should be proficient in the fundamentals, principles and skills involved in preparing typodont teeth for full coverage restorations. This resource should be thoroughly reviewed before beginning the restoration fabrication procedures and should be followed step-by-step to achieve the goals of successful provisional fabrication. The purposes of each characteristic of an ideal restoration should be reviewed and learned prior to fabrication so that the evaluation criteria can be used effectively.
Initially, students using this technique to fabricate provisional restorations had difficulty removing the restorations from the typodont teeth. Through the implementation of lubricating the typodont teeth with Die Lube, the problem was alleviated and restorations could be removed successfully. It is necessary to emphasize that this process of lubricating the teeth is only performed in a preclinical setting and is not necessary or recommended during fabrication of provisional restorations on live patients.
