Summary

This observational analytical in vivo study aimed to assess the dimensional accuracy of diagnostic trial restorations fabricated through four different techniques: condensation silicone matrix without external shell, addition polyvinylsiloxane (PVS)-silicone matrix with an external resin-based shell, transparent addition PVS-silicone matrix with an external vacuum shell, and a CAD/CAM combination matrix.

Methods: Patients (n=20) in need of anterior upper teeth aesthetic rehabilitation were recruited. Clinical and radiographic examinations, intraoral scanning, and dental CAD software were used to design a virtual diagnostic waxing. A 3D printed waxed cast was obtained, and four different matrices were fabricated. Trial restorations were performed using calibrated materials, and intraoral scans were taken for each restoration. Linear and volumetric discrepancies were evaluated using reverse engineering alignment software

Interventions

DEVICE

Device to deliver trial restoration matrix

Auto-polymerization bisacrylic material (Luxatemp Star, DMG) was used to perform the trial restoration for condensation silicone matrix, addition PVS-silicone matrix with external resin-based shell and CAD/CAM combination matrix. Light-cured flowable composite-resin (Filtek Flow, 3M Dental Products) was used to perform the trial restoration for transparent addition PVS-silicone matrix. The rationale behind using different material stands on the material selection usually chosen by clinicians for each matrix. In the same appointment 4 trial restorations were performed to each patient using the four different matrixes.
