Restoration Dentistry

Cergo is a Pressable full ceramic for maximum aesthetic and biocompatible restorations such as veneers, inlays, onlays and crowns.

Both the appearance and material properties resemble natural teeth:

Cergo Pressable full ceramic and Duceragold veneer ceramic combine the benefits of an excellent base material with a hydrothermal ceramic which has the outstanding characteristics of smoothness and natural surface hardness with abrasion behavior similar to the natural dentition.

Golden Gate System stands for tailor-made materials, maximum variety of indications and maximum biocompatibility. As a component of this system, Cergo fits in perfectly when combined with the additional materials within the Golden Gate system. The best results for the layering technique can be achieved with Cergo restorations combined with the Duceragold ceramics. Cergo also works well with the painting technique.

Cergo is a pressable ceramic and can be used in one of two ways, according to the result you require.

  • Firstly it can be pressed “full-contour” and then externally stained to the desired shade – a number of options are available according to the translucency requirements of the tooth, etc etc.
  • A second method is to press a “coping” in the Cergo and then to layer the rest of the crown as per the usual method with individual powders.
  • A dentine-colored ingot is used and the layering powders are one of my favorites – a hydrothermal porcelain called Duceragold. It is a lower-fusing hydrothermal ceramic and has great aesthetic properties, is kind to the opposing dentition, and has a “healing” characteristic.

Indications:

  • veneers
  • inlays (single and multi-surface)
  • onlays
  • crowns (incisors and molars)

Contraindications:

  • bridge structures
  • very deep sub gingival preparations
  • patients with parafunctions (e.g. Bruxism)
  • severely reduced residual teeth
