The technology provides for the installation of a fixed bridge with a support for 4 implants, which at the same time serve as a support for the remaining “teeth”.
The procedure involves the installation of implants for patients with a complete absence of teeth, or for patients with severely damaged teeth that must be removed.
Prosthetics are performed on the same day after the end of the tooth restoration operation in 1 day.
