Subperiosteal Implant- Solution for Deficient Jawbone


Patients who have been denture wearers for an extended time can experience bone loss in the upper or lower jaws just from wear and tear issues.

At Risk - Poor Porosity
for standard implants

Poor oral health conditions, untreated for too long, can also lead to conditions where insufficient bone exists for denture use and the use of traditional or mini implant devices.

Maxillary bone density (upper jaw) characteristics are significantly different from the lower jaw in most individuals. Upper jaw bone tends to be more porous.

With no teeth in the maxilla (upper jaw), the bone internal to the ridge tends to be lost over time. The porosity gets so great that implants have no internal bone in which to hold. Though the ridge may look sufficient from the outer surface, an x-ray may show total lack of bone density. Many times even repeated attempts at bone grafting prove unsuccessful.

Subperiosteal Implants

Dentists and oral surgeons who have access to and, perhaps more importantly, experience in subperiosteal surgeries, offer this implant device as a viable solution for patients who lack sufficient bone for traditional implants.

Patients unable to successfully wear a maxillary denture who lack bone density for root form implants find great comfort in maxillary subperiosteal implants.

Custom Formed Framework

Titanium, the same metal used to make standard root form implants, is used to construct the implant framework. Molds of the upper jaw bone are created by exposing the bone and taking an impression. A second method using a Catscan 3 Dimensional x-ray has been helpful in fabricating the custom fitting framework. The implant posts for the patient pictured here are a part of the framework.

The adjacent photo of a custom subperiosteal implant is used for illustration only.... demonstrating how the framework is molded over a stone model created from the impression molds taken of the maxillary ridge.

Notice the snug fit around the entire ridge. The implant posts sit on the very top of the bone.

Grafting products are added to the surgery site to completely fill any space between the framework and the patient's jawbone. The titanium framework will fully integrate into the maxillary bone

The next adjacent photo is the actual subperiosteal device that was used with this patient. The white coating is hydroxyappetite, a substance that mimics human bone and assists in integrating the implant framework with the jawbone.

Technical data generated from his diagnostic studies and x-rays indicated a 4 implant post device as being the ideal configuration for distributing the physical and biting forces across the entire jaw.

Health Considerations for Healing                      

Maintaining healthy blood supply in the surgery areas is an important key element for healing to take place normally. Cigarette smokers should or must cease smoking if healing and tissue regeneration is to be optimized.

Patients who are diabetic may have special medical considerations, depending upon their diabetes treatment histories.

Restorative Planning: Choices and Options

The process of deciding which teeth replacement options is usually underway at this point. Assessments for recreating a normalized bite height, or vertical dimension have been made.

Cosmetic options provide the patient the opportunity to select sizing, coloration, shading and styling the smile line, the LVI Rule of Golden Proportions that uses a mathematical model for creating the perfect smile.
