The loss of dental tissue can be linked to several causes: a cavity, a crack or a break in a tooth, the loss of a filling, etc. Depending on the volume of this loss, the restoration technique used will be different:

• low volume: direct dental chair technique

  • fillings of limited volume (decay by replacing amalgam, fracture, tooth in bad position),

  • fillings of the furrows of the lacteal or permanent teeth ( preventive sealing of the furrows ).

• large volume: indirect technique with an imprint sent to the laboratory.

  • large volume fillings or partial covering on a posterior tooth (significant decay, loss of a filling, fracture of part of the tooth, etc.), we speak of inlay or onlay .

  • partial covering on an anterior tooth, we speak of a facet ,

  • total covering of the tooth on existing dental root, living or devitalized, we speak of crown ,

  • absence of one or more teeth (root extracted, agenesis), we speak of implant or bridge,

  • replacement of several missing teeth, adjacent or not, with a partial removable prosthesis (removable because it is not bonded, partial because it does not replace all the teeth),

  • replacement of all the upper or lower teeth with a complete removable prosthesis often called "denture".
