Construction of FPD
Clinical and Laboratory steps
Diagnosis(History, TMJ evaluation, Intra/extraoral examination, Diagnostic casts Full mouthradiographs)
Treatment Plan → Abutment Preparation → Temporary FPD → Impressions→ Registry of Occlusion
Try in and shade selection
Try in and cementation

WAX PATTERN FABRICATION
➢ First step: making retainer’s caps
➢ After it: building the surfaces of the full-metal crowns or the metal framework of theveneered crowns (occlusal, vestibular, oral, mesial, distal) with wax added technique

Adapta deep drawing system
Inexpensive and long-proven system using special plastic films.
The alternative to wax dipping; simple, fast deep
drawing of crown caps. Crown caps made with Adapta film with their high stability.
The thin film, transparent or red, systematically provides the necessary space for luting cement
