Atlanta Dental Implant FailureMost dental implants placed today are root form implants.
Root form implants problems can be classified as ailing, failing, or failed:
Mechanical FactorsBroken or fractured implant screws: The crown or abutment is attached to the implant by a screw. If the screw is fractured it must be properly removed to prevent damage to the implant.
If the implant device is damaged it usually has to be removed. The implant site is then re-prepared with additional bone graft material and a new implant replacement.
Loosening screws: Implant screws that become loose should be immediately replaced with a prosthetic screw provided by the implant manufacturer, not a generic laboratory type screw, for the highest quality.
Osseointegration FactorsOsseointegration Failure: Unfortunately, a popular cause of implant failure if certain protocols are not followed closely. Optimal integration of the implant device into the jawbone requires an acceptable level of healthy bone (porosity values + ample blood supply), matching of implant size to location in jaw, proper site preparation and suitable bone augmentation (bone grafts) deemed necessary.
FracturesFractured implants: Using the wrong type, size, quantity, position or length of implant, thereby causing over loading, may result in implant failure. It is imperative that the fractured implant be removed as atraumatically as possible.
Fractured abutments: The principle concern is to maintain the health of the implant. In some cases the abutment may simply require a new screw. Other cases may require remaking the abutment and/or crown.
More Failure CausesProsthetic failures: The initial design of the prosthesis plays a large role in the serviceability. Large multi-unit bridgework should be screw retained. Although they are more costly and complex initially, they generally do not have to be completely remade in the event a repair is necessary.
Tooth material failures: Implant restorations can also fail due to the type of crown material and the health of opposing teeth. Combinations of porcelain products, acrylic products and various formulations of silver crown alloys and gold crown alloys are used by Dr. Mc Farland to create the dental function and cosmetic appeal desired by the patient.
Important SummaryImplants can and do fail from time to time... for a variety of reasons. Patients who suspect they have a loose implant or tooth should seek an immediate evaluation. Regardless of what component or event is causing the failure, a loose implant can cause lateral occlusal forces that can destroy the implant or cause damage to the implant site.
