Reconstructive Cosmetic and Implant Dentistry

Dental Implant Failure

Most implants placed today are root form implants.

Root form implants problems can be classified as ailing, failing, or failed:

Failed implant - if the implant has any mobility the only acceptable treatment is removal
Failing implant - if checkup x-rays show increased bone loss around the top of the implant, the cause must be determined and corrected. The cause could be poor oral hygiene, a bad bite or a host of other reasons. After correcting the problem the resorbed bone should be grafted
Ailing implants - the least severe of the three categories. Any signs of inflammation, redness or mild bone loss may be signs that the implant is not completely healthy or the implant screw is loose

Mechanical Factors

Broken 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.

Repair parts

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.

Osseiontegration Factors

Osseointegration 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.

Osseointegration Tissue Regeneration Failure

Osseointegration can also fail due to premature loading of the implant restoration. It is generally accepted that osseointegration can require 3-6 months or more, depending on preoperative oral health conditions.

Fractures

Fractured 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.

Broken Implant Screw

More Failure Causes

Prosthetic failures: The initial design of the prosthesis plays a large role in the servicablity. Large multi-unit bridgework should be screw retained. Although they are more costly and complex inititally, 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. Koeppel to create the dental function and osmetic appeal desired by the patient.

In some instances the choices of acrylic versus porcelain may require extra consideration of unusual occlusal forces or dynamics. Dr. Koeppel routinely evaluates the health and condition of opposing tooth structures to assure, for example, that a brand new implant and crown does not cause an opposing natural tooth to wear down quickly (or possibly fracture). Restorative materials are selected to promote health of all opposing teeth.

Important Summary

Implants 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.
