First presentation of Primero On the IDS in Cologne

On March 12^th, 2014 Primero crowns and bridges  were for the first time presented at the International Dental Show (IDS) in Cologne, Germany, as the safe alternative to glazed monolithic zirconia restorations, that are extremely hard and cause median cracks in the antagonist teeth. Between 2014 and 2020 45.000 Primero elements were produced by dental laboratories for dental clinics. The 6 years clinical performance of the Primero restorations was excellent: no chipping and no deterioration of the restorations occurred. The Primero Lab System makes it possible, for every laboratory with a 5-axis milling machine, to produce, at relatively low cost and effort, esthetic veneered zirconia restorations for all indications, without the need of a ceramist. The new procedure is simple and staightforward and makes use of a porcelain paste with tixotropic behavior, so that it flows easily onto the zirconia substructure placed in a negative form milled in a transferblock. After micro-wave drying, the dense porcelain is milled to high precision and fired as usual in a vacuum porcelain funace. Final finishing is minimal, due to color gradients in the crown, similar to natural teeth.
