Classification of dental implants depends on a number of criteria, but many types of implants are designed for use in the current state of the bone tissue and the jaw of the patient. A number of dentists are paying more attention to the classification of dental implants on the material of their making, separating artificial roots for:
- Biotolerant (chromium-cobalt alloy or stainless steel);
- Bioinert (gold, zirconium, titanium, glassy carbon, corundum ceramics);
- Bioactive (covered by tricalcium phosphate ceramics or hydroxyapatite).
Types of titanium implants
Thanks to the good ability of getting used to human bone tissue, titanium artificial roots were widespread, so we can distinguish titanium implants according to the form:
Most dentists use titanium orthopedic implants of screw shape. They are securely screwed into the bone and provide a perfect fitting denture.
Cylindrical dental implants (and tube) are used less frequently; they are used only to make up for some of the teeth or to support the whole fixed prosthesis in the absence of the teeth.
There are laminar and stage implants. These are artificial roots that resemble the living root of the tooth. Another type is implants with cortical plates.
Despite the variety of structural forms of artificial root and basis, in fact each implant has a special porous coating that matches the native porosity of jaw bone.
