Classification of Dental Implants

Endosteal Implants are placed within fully or partially edetulous alveolar ridges with sufficient residual bone. Some endosteal implants are attached to components. Common systems are one stage and two stages.

1. Root Form Implants are designed to resemble the shape of a natural tooth root. Usually are circular in cross section. Root forms can be threaded , smooth, stepped, parallel side or tapered, with or without coating, with or without grooves or vents and can be joined to a wide variety of components for retention of a prosthesis.

2. Plate / Blade Form Implants is the basic shape of the plate / blade form implant is similar to that of a metal plate or blade in cross section. Some plate / blade dental implants have a combination of parallel and tapered sides.

3. Endodontic Stabilizer Implants differ from other endosteal dental implants in terms of functional application. They are used to extend the functional length of an existing tooth root to improve its prognosis, and when required, its ability to support bridgework.

4. Ramus Frame Implants have been demonstrated to be safe and effective. They are intended for the treatment of total mandibular edentulism with severe alveolar ridge resorption.

5. Transosteal Implants are the most surgically invasive and technique sensitive. Transosteal Dental Implants feature a plate that is placed against exposed inferior border of the mandible, with extensions that pass from this plate through the symphyseal area, out of the crest of the ridge and into the oral cavity.

Subperiosteal Dental Implants are placed under the periosteum and against bone on the day of insertion, rather than within alveolar bone.

Intramucosal Inserts differ in form, concept and function from the other modalities. They are mushroom shaped titanium projections that are attached to the tissue surface of a partial or total removable denture in the maxilla and plug into prepared soft tissue receptor sites in the gingiva to provide additional retention and stability.
