What Is the Difference Between Endosteal and Subperiosteal Implants?

Once dental implants are complete and the crown or bridge is placed, they look and feel just like natural teeth, however, these teeth will not develop cavities. A dental implant is essentially an artificial root for a dental prosthesis (e.g., dental crown). An individual may receive one dental implant to replace a single tooth or several dental implants to replace multiple teeth. If multiple teeth are being replaced, the prosthesis used is similar to a dental bridge.

Why Do People Choose Dental Implants Over Traditional Dentures?

Dental implants are much more convenient than traditional dentures because, unless the patient chooses to have a removable bridge (i.e., overdenture) this solution for missing teeth remains in the mouth. Furthermore, dental implants do not require any type of adhesive to hold them in place.

The Two Main Kinds of Dental Implants: Subperiosteal and Endosteal

The two most commonly used dental implants are subperiosteal implants and endosteal implants. If you are considering dental implants, you should know the difference between these two.

Subperiosteal Implants

The subperiosteal implant is placed beneath the gingival tissue (i.e., gum). These implants are placed over, above or on the jawbone, which means there is no drilling into the jawbone necessary when subperiosteal implants are used. These implants are ideal for individuals who have jawbones that are poorly developed.

The Subperiosteal Dental Implant Procedure

This procedure has two stages. During the initial stage, the patient’s gum is exposed. Impressions of the jaw bone are taken. These impressions are used to create a custom-designed metal frame.

Incisions are created in the gingival tissue. These incisions allow for the insertion of the custom-tailored metal frame that will sit across the jawbone. The incisions are closed with stitches. This step is complete. Now, before starting stage two, the patient recovers for a few weeks.

Once a few weeks have passed, the patient returns to the office to have the crown or bridge attached to the metal frame. Subperiosteal implants benefit individuals who lack a sufficient amount of jawbone, which has resulted in weaker jaws.

Endosteal Dental Implants

These are the most common type of implant used. Endosteal implants consist of a screw that is placed into the patient’s jawbone. The screw actually serves as the artificial root for the crown, denture or bridge that will be attached. Since these implants are installed into the jawbone, this process is gradual and could take several weeks or months.

Once the implants are placed, the patient’s bone will begin growing into it, essentially making the implant part of the jawbone. This unique ability is referred to as osseointegration and takes several months to complete.

Once osseointegration has taken place, the visible portion (e.g., crown, denture or bridge) of the implant can be placed.
