A dental implant consists of
(1) the body: the part where an existing denture is implanted as human tissue
(2) the neck
(3) the base post or abutment.
1. Body: the part where the implant is implanted into human tissue. According to its implantation site, it can be divided into: A. Implanting into mucoperiosteum or B. Implanting into soft tissue.
2. Neck: the part that connects the body with the foundation pile or abutment. 3. Pile or abutment: it is the part of the dental implant exposed outside the mucosa, which provides support, retention and stability for the artificial denture of its superstructure.
dental implants are divided into
1. metal and alloy materials: including gold, 316L stainless steel (iron-chromium-nickel alloy), cast cocrmo, titanium and alloy.
2. Ceramic materials: including biologically inert ceramics, bioactive ceramics, biodegradable ceramics, etc.
3. Carbon materials: including glassy carbon and low-temperature isotropic carbon.
4. Polymer materials: including acrylate, PTFE, poly maple, etc.
5. composite materials, that is, the combination of two or more of the above materials, such as spraying ceramics on metal surfaces.
At present, the commonly used materials for dental implants are mainly pure titanium and titanium alloys, bioactive ceramics and some composite materials.
oral implants are divided into
1. intraosseous implants: implants are located in the jaw
2. subperiosteal implants: implants are located on the bone surface under the mucoperiosteum
3. endodontic implants: implants are located in the root canal treated by root canal
4. bone-penetrating implants: implants are implanted into the jaw from the lower edge of the mandible and pass out of the alveolar cavity.
