Dentrade – for the most widely varying demands

All-cast crowns
Also called a “gold crown” or “metal crown”, it meets all of the functional requirements and stands out due to its very long service life (as far as material is concerned).

As a rule, it is made from a precious metal alloy; depending on the social situation, “economy alloys” (reduced gold, free of precious metals) may also be used. The new fixed-subsidy system subsidizes only NEM (non-precious metal) crowns – the outer appearance is then generally of a silver colour, which is generally not a problem in the non-visible areas.

Brückenersatz, in English: bridge, bridgework, fixed partial denture; fixed (except for a removable bridge) parodontally supported/worn denture, which is attached to abutment teeth via an anchor or retainer (usually crowns). This results in a situation where the (chewing) forces impacting the bridge – as in a natural bite – are absorbed exclusively by the abutment teeth. These have varying levels of suitability for this purpose (significance of abutment teeth).

A bridge always consists of bridge anchors and bridge interlinks – thus, natural teeth or implants (implant bridges) and/or a combination of the two may serve as the anchor.

Post Crowns
Post crowns are now only historically designated as a type of crown ("pivot tooth"), since in previous times there were procedures where the crown and the post were manufactured as a unit. Today the crown is more correctly called: "crown with post anchoring” or “crown with post and core", in which the term "post" is not to be taken literally, since screws and individually cast structures are also used.

Use: If the visible part of the tooth is so badly destroyed such that a crown would no longer find adequate hold or support. This always presupposes a completed root canal treatment.

All-ceramic crown
This is still considered "the crown of crowns" today, since if properly manufactured it can barely be distinguished from a natural tooth even by a specialist. Base material is comprised of ceramic mixtures, which can be individually adapted to the natural teeth in an expensive manufacturing process. Colour-adjusted cements or plastics are used for the final insertion, to prevent any colour distortion from deep below.

Faced Crown
To cover up the cosmetic deficiencies of the all-cast crown, the respective crowns are coated ("faced") partially or entirely with a tooth-coloured material. Plastics or ceramic mixtures are the materials used.

Similar to the partial crowns, the veneers do not cover the entire tooth, but only a portion of it:
Extremely filigreed ceramic facets (0.5-0.8 mm, less frequently made from high-quality plastic) can be processed if the tooth (incisor) has acquired an unattractive appearance due to fillings or defects in the enamel or if there is a cosmetically objectionable gap (diastema) between the incisors.
Preparation: The tooth is only finely prepared in the visible area, and thus only loses a small amount of tooth substance compared to the all-ceramic crown.
The very laborious preparation (at the dentist’s office or in the lab) may take place (less often) in just one sitting directly on the patient using a plastic or ceramic veneer ("chair-side"; direct method) or in two sittings after taking an impression and manufacturing in a dental laboratory ("lab-side"; indirect method). With the laboratory method, cosmetically superior ceramic shells are used almost exclusively. The veneers are attached with a special “adhesive” using adhesive technology.
