Failed Dental Implants
The cause and effect relationships underlying dental implant failure are complex and can be quite confusing for patients considering this famed Gold Standard of Tooth Replacement.
Issues can include improper placements, using the wrong type, size, quantity, position or length of implant during surgery.
Fractured abutments, prosthetic failures, even tooth material (acrylic versus porcelain) can be a factor.
Surgical factors that affect the osseointegrative process, prior to loading, can cause an ultimate failure. Disease, oral health habits, smoking and friction (pontic or flipper causes friction on healing tissue) may cause a need for re-treatment.
This gallery contains examples of different types of implant failures that can occur in bridgework treatments (fixed bridges) or individual tooth replacements.
19 Year Implant Failure. Nineteen years of service from a dental implant is quite good really. Unfortunately, the lack of even the most basic routines of daily care, caused a mandibular implant to fail. Signs of infected tissue can be seen, along with an eruption of the implant device.
Repair and replacement options would require removal of the failed implant and infected tissue, tissue grafting to restore what was initially lost, new implant placement, mini implant placements, fixed bridge, overdenture, implant retained dentures.

Implant Failure

Implant bridge failure. What started out as a failed implant on one end of this bridge.... developed into a complete failure in about 9 months. The loose implant gradually caused the bridge device to move about, change occlusal relationships with the upper jaw and end up creating damage across the entire bridge. A complete failure that could have been avoided.
Repair and replacement options would require treating the failed implant, possible renewed grafting and implant replacement, treating infected tissues, replacement with a choice of multiple implants and crowns, cemented bridge product, a replacement implant supported bridge or denture product.
