Purpose/Aim 

To describe a novel step-by-step technique that helps dental clinicians fabricate predictable direct full-arch provisionals.

Introduction

Clear matrices used for jet provisional fabrication are typically flimsy resulting in difficulty making predictable chairside provisionals. This issue is avoided by adapting a matrix for provisional fabrication over a diagnostic wax up cast. Before removal of the first matrix from the cast a second, more rigid, matrix is adapted over the first. This double layer is then removed from the cast and trimmed in the traditional manner. The use of this novel matrix technique presents multiple advantages over a single layer technique. The more pliable inner layer more accurately replicates fine detail while the thicker outer layer supports the less rigid layer and prevents it from warping. Additionally, the more rigid outer layer allows for a more secure and predictable seating, ensuring a provisional that resembles the wax up as closely as possible.
