Dental Implant Failure

Unfortunately, dental implant failure is a common occurrence.

Even when proper procedures are followed, things can go wrong. When you're dealing with the human body, it isn't possible to have 100% predictable outcomes. But when treatment and restoration standards are compromised, the failure is almost unavoidable.

Types of Dental Implant Failure

Causes of Dental Implant Failure

Some failure happens despite the best efforts of the dentist and the patient. But some is a result of the natural tendency of both dentists and patients to look for the shortcut, the cheaper solution, the easy road. Here are some of the causes:

• Shortcutting the diagnostic phase - Some dentists are trying to place dental implants with only a two-dimensional panographic x-ray. While a panographic x-ray is adequate for most dental surgery, it isn't enough for properly placing implants. The amount and quality of bone available to support the implant, and the exact position of nerves and blood vessels that run through the bone, and the shape of nasal sinuses and other anatomic structures are three-dimensional questions. Dr. Chal is the only dentist in Arizona to hold advanced credentials in implant dentistry, cosmetic dentistry, and general dentistry at the same time. Dr. Chal believes that only carefully done CT scans, analyzed by a specialist in maxillofacial radiography, provide the level of information needed for these demanding procedures. These 3-D CT scans take less than three minutes to take, and the radiation exposure to the patient is less than 3% of the radiation received during a medical CT scan. Dr. Chal then has the computer provide printouts of one-millimeter cross-sections of the jaws showing the exact locations of blood vessels and nerves and the thickness and quality of bone.
• Inadequate medical history - There are many medical conditions that affect the success of dental implant treatment. Again, thoroughness and care by the dentist here can prevent dental implant failure later.
• Inadequate dental implant fixtures - There are over two hundred companies that manufacture these fixtures, but only six of them have published juried research with test results documenting the quality of those fixtures. Research is expensive, and some dentists are attracted to the companies that have cut costs and offer cheaper fixtures. The cost of a substandard fixture can be as little as one-one hundredth of the cost of a carefully manufactured, precision-engineered, and fully tested fixture, so this can be a powerful temptation for some dentists. But those shortcuts can come back to haunt the patient long after treatment is completed.
• Incorrect dental implant placement - This could be tied to an inadequate diagnosis, because it's during the diagnostic phase that the decision is made where to place the implant. It could also be a lack of communication between the restorative dentist and the surgeon.
