(1) Body: Denture is the place where human tissues are implanted.
(2) the neck
(3) Pile or abutment.
1. Body: It is the part where the implant is implanted into human tissue. According to its implantation site, it can be divided into: a. implantation in mucoperiosteum or b. implantation in soft tissue.
2. Neck: It is the part that connects the body with the foundation pile or abutment. 3. Post 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.
According to different materials, oral implants can be divided into
1. metal and alloy materials: including gold, 3 16L stainless steel (iron-chromium-nickel alloy), cast cocrmo, titanium and alloy, etc.
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, polytetrafluoroethylene and polyethylene.
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 two types according to the planting mode and the planting position.
1. Intraosseous implant: The implant is located in the jaw.
2. Subperiosteal implant: The implant is located on the bone surface under the mucoperiosteum.
3. Implantation in root canal: The implant is located in the root canal receiving root canal treatment.
4. Transosseous implantation: implant the implant into the jaw from the lower edge of the mandible, and attach the periosteum to the top of the alveolar ridge.
