The main difference between endosteal and subperiosteal dental implants lies in their placement within the jawbone. Endosteal implants are placed directly into the jawbone and are the most common type of dental implant. Subperiosteal implants are placed on or above the jawbone, just below the gum tissue. The choice between these implant types depends on factors such as the amount of available bone, the overall oral health, and the specific requirements of the individual case.

The primary difference between them lies in their placement within the jawbone:

Endosteal Dental Implants: Endosteal implants are the most widely used and common type of dental implants. They are surgically placed directly into the jawbone. These implants consist of small titanium screws or posts that bond with the bone during the healing process. Once integrated with the bone, they provide a sturdy foundation for attaching various dental restorations. Endosteal implants are typically used for individuals with sufficient healthy bone mass and are suitable for single tooth replacements, multiple teeth, or even full arches.

Subperiosteal Dental Implants: Subperiosteal implants, on the other hand, sit on top of the jawbone but beneath the gum tissue. They are not embedded into the bone but are instead placed on or just above the bone and secured with metal framework posts that protrude through the gum. Subperiosteal implants are often used when a patient has inadequate bone height or density for endosteal implants and may not be suitable candidates for bone grafting. These implants can support dental prosthetics effectively and are a viable option for individuals who need implant-supported restorations but have limited bone volume.
