Here's the final #DentalDecathlon case! #FeatToFabricate
"As a wholesale chrome lab, we often get caught up in the mundane standard procedure frame. Every once in a while, you get a...See more challenge. This frame proved to be somewhat difficult because of the severe undercut of these lingually inclined teeth. With virtually no buccal undercut, and literally no room for a normal bar or plate, we had to get creative, so we came up with this.
Utilizing the lingual undercut on #20 with a modified T clasp, we gained retention for the partial. Then we encircled the buccal and occlusal with a metal clasp and rest, creating strength as a major connector. This eliminated "food traps" while also providing the support needed. Then, we balanced the LINGUAL undercut of #20 with a LINGUAL retentive clasp on #28 providing good retention overall for the partial. We were able to also gain some slight retention on the mesio-buccal of #22 while "hooking" the guide plane in the mesial undercut #27.
Materials used were Nobilium: Dental lab products, supplies and equipment.'s Nobilstar Ultra, Yellow Stripe investment and Austenal patterns. The case was made early 2007 and is still functioning well today." - Jerry Robinson and the Chromeworks, Inc. team
