Subperiosteal Implants

A subperiosteal implant is custom-made for each patient


Subperiosteal implants are dental implants that generally sit on top of a patient’s jaw bone, but are placed under the gum. . A subperiosteal implant is custom-made for each patient, and has a lightweight metal framework that comfortably but securely fits over the patient’s jaw bone.

Subperiosteal implants are often used to secure a patient’s dentures in cases when the bone has receded or atrophied, and the jaw bone mass has become very limited. This type of dental implant may be used in limited areas of the mouth where several teeth are missing, or can also be used in the whole mouth when all of the teeth are missing. Subperiosteal implants are designed in such a way that they can result to the equivalent of multiple (natural) tooth roots.

Steps in the Placement of Subperiosteal Implants

1. The dentist will make an impression of the patient’s jaw bone, to be able to construct

custom-made subperiosteal implants. The impression can be done in two ways: through a CAT scan of the jaw bone, or by getting an impression of the jaw bone itself after an incision on the gums has been made.

2. After the jaw bone impression has been made and the custom-made subperiosteal implant is ready, the dentist or dental surgeon makes an incision in the patient’s gums to expose the jaw bone underneath. The subperiosteal implant is then screwed into the jaw bone, with small nodes left protruding through the gum line. The dentist or dental surgeon will close the gums with stitches afterwards.

3. A healing period of three to six months will be needed, to provide the subperiosteal implants with sufficient time to successfully integrate with surrounding tissue.

4. After the healing period has passed, dentures are then prepared to be attached securely onto the protruding nodes of the subperiosteal implants.
