[Digital workflow with the Lava Chairside Oral Scanner C.O.S. and Lava technique].

Abstract

This article describes the clinical procedure and functioning of the LAVA C.O.S scanner (3MEspe) in making digital impressions of patients. When used in combination with LAVA technology, fully ceramic tooth replacements can be produced in an entirely digital way. After scanning the prepared abutment teeth, the data is directly transmitted to the dental laboratory to enable the production of the ceramic structures, while, on the other hand, stereo lithography can be used to produce master models. The milled and sintered zirconium oxide caps are covered with system-specific baked ceramics on the model. Initial clinical results have confirmed the functionality of the system. C.O.S-(Chairside Oral Scanning) is a true innovation in reconstructive dental medicine.
