case report _ restorative dentistry I achieve a satisfactory result from a visual per- spective. In the LABORATORIO DENTAL FONTCAR laboratory, we met this challenge by com- bining the aesthetic possibilities afforded by VITA SUPRINITY using the cutback technique with the low-melting fine-structure feldspar ceramic VITA VM 11. _Milling and reworking The inLab MC XL system (Sirona Dental) was usedforvirtualdesignandmillingofthecrowns. Following the CAM process, reworking of the new high-performance glass ceramic should only be carried out at low pressure using fine- grained diamond-tipped milling tools as well as special polishing instruments. For cost-effective surface processing that is gentle on the ma- terial, the technical and clinical versions of the VITA SUPRINITY Polishing Set are recommended. For crystallisation firing, any vacuum furnace that supports slow cooling can be used. The crowns can be placed directly on to honeycomb firing trays with platinum pins, without using firing paste. _Final result Despite the unfavourable initial situation, VITA SUPRINITY enabled a comparatively good final aesthetic result to be achieved in highly efficient fashion, restoring the patient's natural smile. The expectations and hopes of the pa- tient and the entire treatment team were met in full. We would like to thank master dental technician Thomas Gausmann for his enormous local support._ Editorial note: This article is a reprint from DENTAL- ZEITUNG,No.1/2015,OEMUSMEDIAAG,Germany.

I 25CAD/CAM 4_2015 Daniel Carmona Cando, a master dental technician from Barcelona,Spain, uses the following complex patient case to report on how laboratory users can achieve excellent results withVITA SUPRINITY restorations. This article provides a step-by-step explanation of howVITA SUPRINITY and theVITAVM 11 veneering ceramic can be used to achieve aesthetic results in a challenging clinical scenario.
