3D‐Printed Ultra‐Thin Non‐Prep Lithium Disilicate Veneers: A Proof‐of‐Concept Clinical Case

ABSTRACT Objective To test the clinical application of LCM‐printed lithium disilicate veneers. Clinical Considerations A female patient with tooth wear was scanned with intraoral scanner (Prime Scan, Dentsply Sirona). The six non‐prep veneers were designed (DentalCAD, Exocad) and printed from lithium disilicate with an LCM‐printer with the thickness of 0.1–0.2 mm (CeraFab System S65 Medical, Lithoz GmbH). The green parts after printing were cleaned of the excess slurry and debindered in a furnace (Nabertherm, Lilienthal) until 430°C with a dwell time of 5 h to remove all polymeric binder. The resulting parts were sintered in an oven (Programat P510, Ivoclar Vivadent AG) at a temperature of 900°C. The supports were removed with a dental technician handpiece (Perfecta 900, W & H). The final restorations were stained (e‐max Ceram, Ivoclar Vivadent AG) by a master dental technician. Conclusions The six LCM‐printed ultra‐thin non‐prep lithium disilicate veneers were tried‐in on the patient using a try‐in glycerin gel (Ivoclar Vivadent, Schaan, Lichtenstein) and demonstrated excellent fit and esthetics. LCM technology enabled the production of ultra‐thin non‐prep lithium disilicate veneers with layer thicknesses of down to 0.1 mm. Clinical Significance The 3D‐printing of ultra‐thin non‐prep veneers is technically feasible and provides an adequate clinical outcome. Additive manufacturing of ultra‐thin non‐prep lithium disilicate veneers may pose a valid alternative to conventional and subtractive manufacturing.
