The diagnostic template in the digital era: A technique for fabricating a diagnostic trial restoration by using a two-piece additively manufactured index.

Abstract

Diagnostic trial restorations, traditionally fabricated from silicone or vacuum-formed matrices formed on gypsum or 3-dimensionally (3D) printed diagnostic casts, have been widely used for the intraoral verification of the virtual design of prosthetic or esthetic rehabilitations. A step-by-step digital workflow for fabricating trial restorations is presented that transfers the virtual treatment plan intraorally using a 2-piece 3D printed index that does not require a diagnostic cast. Additionally, the design enables sequential removal from the mouth without displacement of the trial restorations.
