- According to the place of fixation: intraradicular, intracoronal, intercoronal and auxiliary.

Features of product installation
The structure is fixed in several stages:
- To begin with, the jaw must be prepared for installation. To do this, the enamel is cleaned with ultrasound, the pathologies of the oral cavity and teeth are treated. In addition, you will have to perform a small grinding of the crowns.
- Additional processing of supporting teeth for the installation of a prosthesis and locks. They need to installspecial porcelain-fused-to-metal crowns, as they will subsequently bear the majority of the masticatory load.
