Different Types of Implants

With proper patient selection, the ADA considers two kinds of implants safe:

• endosteal
• subperiosteal

Like tooth roots, Esdosteal implants extend into the jawbone.  A sufficient amount of bone is required to support this type of implant.

After placement, the gum tissue may be stitched over the implant for a period from three to six months.  During this time the bone attaches to the implant in a process called osseointegration.  A second surgery would be needed to attach a post to the implant.  Artificial teeth then can be attached to the posts - individually, or grouped on a bridge or denture.

A subperiosteal implant can be used if there is not enough bone present to support an endosteal implant.  The subperiosteal implant is a metal frame that fits on the jawbone beneath the gums.  As the gums heal, the implant becomes fixed to the jaw.  Posts, which are attached to the frame, protrude through the gums.  As with the endosteal implant, artificial teeth then are mounted to the posts.
