Failed Dental Bridges
Cosmetic bridgework can be created with two different types of support systems.
Implant supported bridges are anchored with traditional dental implants on each end of the span. The infrastructure, or framework can be made of metal, zirconia and different grades or types of procelain. Depending on the length of the span, additional support implants or natural tooth structures may be incorporated within the span. Implant supported bridges are considered to be superior to bonded or cemented bridgework
Dental bridges that are anchored by natural teeth that are prepared to accommodate an especially prepared crown on each end of the bridge that is an integral part of the bridge device. Support structures may also be used along the span as needed. Bonding compounds are used to attach the bridge to the anchor teeth.
Bridgework that traverses an entire arch are usually categorized as a fixed bridge, attached by screws into strategically placed implants. This type of bridge is usually removed only by the dentist for cleaning and oral health maintenance purposes. A metallic framework usually incorporated to provide strength and long term endurance.
Acrylic bridges exist in the form of a denture product, which can be removal or non removable and supported either by implants, mini implants (actually a retention device-the denture still rests on the gum tissue) or gum tissue alone.
This gallery contains examples of common bridgework that has failed for any one or more several causes, which can include failure due to leakage and decay around anchor teeth, failure of dental implant anchors, cracked or broken due to occlusal factors, or failure due to bacteria build up that results from poor or untimely maintenance
Super Glue to the Rescue!! Strangely enough.... lots of people with failing bridgework send us questions about using super glue or krazy glue to do their own bridge repairs. This patient was bold and decided to use the glue product even on the anchor teeth....which is shown here to have oozed out and into the gum tissues surrounding the anchor teeth. Toxins, anyone?
Repair and replacement options would include extractions of all failed tooth structures, periodontal therapies to treat any and all tissues coming into contact with the glue product, choice of multiple dental implants, crowns, grafting surgeries, installation of a fixed or removal bridge, denture partials.

Severe Bridge Failure and Super Glue
Ira Koeppel, DDS |
Instead of Super Glue - How about Denture Adhesive?
There is nothing inherently wrong in being creative when it comes to making a bridge or denture product last longer. What many patients don't realize... until it is too late... is that finding a way to "make do" for a few weeks or months more can serve to damage or destroy the occlusal balance. Bone and gum tissues will also be affected. Delaying treatment too long, in an effort to conserve finances... can, for some patients, add unnecessary expense beyond the cost of a simple replacement.
Repair and replacement options couold include treating hard and soft tissues (possible grafting), fabricate new prosthesis (bridge or denture), use of standard or mini implants, fixed bridge, cemented bridge, a replacement implant supported bridge or denture product.

Denture Adhesive Doesn't Work
D. Marinic, DDS |
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.

Implant Bridge Failure caused by Negligence
Ara Nazarian, DDS |
Cemented Anterior Upper Bridge failure. This elderly female patient tried to "make do" for way too long of a period. The entire upper bridge became a wiggly - wobbly mass through leakage and bacteria buildup. Notice how the original tooth structure supporting the cemented bridge completely failed, causing tooth breakage. The middle support tooth was infected down through the root, causing the entire tooth to detach from the maxilla.
Repair and replacement options would require treating periodontal tissues and removing residual bacteria, 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.
