Dental implants are one of the most desired tooth replacement options, and you will have a few different choices to make when considering implant devices. While most implants are inserted directly into the jaw, others are actually secured on top of the bone. These tooth implants are called subperiosteal implants. Keep reading to learn about some facts about these devices.
They Are Not Always Used
If you speak to your dental professional you will learn that endosteal implants, which are placed in the jaw, are far more common than subperiosteal varieties. The endosteal varieties are secured directly in the jaw bone and are quite secure after you go through the healing process. Subperiosteal ones are not nearly as strong and secure and they do have a higher rate of failure.
However, subperiosteal implants can be used in situations where jaw insertion is just not possible. If you have a thin jaw bone and are ineligible for a bone graft procedure, then this type of device may be best. Also, complicated anatomy involving nerves, sinus cavities, or implants that have been previously inserted may lead to the need for an implant that sits on the jaw.
If you have health problems that can interfere with bone healing or if you take a medication that does not allow for substantial bone remodeling, then these may be factors considered by your dentist as well.
They Require Two Surgeries
One of the benefits of the subperiosteal dental implant is the fact that healing can occur at a much faster rate since jaw osseointegration is not a significant concern. This means that you will be able to receive your implant tooth a bit more quickly. While this is true, you will need to prepare yourself for multiple surgeries.
During the first surgery, your dental professional will expose the jaw and take a mold of the bone. This is necessary since the subperiosteal device must be custom formed to match the exact shape and curvature of the jaw.
Your gum tissues will be closed once the mold is created. The mold is then used to create the framework part of the device. And, when the framework is ready, the gums are opened again to reveal the jaw where the frame is attached. The gums are closed afterward and a post will sit above the gum line so that the artificial tooth can be attached once the soft tissues and bone heal.
