Which of the following are the main types of dental implants?

The main types of dental implants are endosteal and subperiosteal implants. Endosteal implants are the most common type, placed directly into the jawbone and often taking the form of screws, plates, or cylinders. This type of implant provides strong support for artificial teeth, as they integrate with the bone.

Subperiosteal implants, on the other hand, are placed under the gum but above the jawbone. This option is typically considered for patients who do not have sufficient height in their jawbone and are not suitable candidates for bone grafting procedures. By being placed underneath the gum, they help anchor the prosthetic teeth in a way adaptable to those with anatomical considerations.

The other types listed do not represent the main classification of dental implants. Cylindrical and conical implants refer more to the shapes of implants rather than types. Fixed and removable implants are terms that describe how the dental prosthetics are secured rather than classifications of implant types. Transosteal and ramus frame implants are less commonly used and pertain to more specialized surgical procedures. Thus, endosteal and subperiosteal remain the primary categories of dental implants commonly utilized in practice today.
