Dental Implants Failure
Why do dental implants fail?
Dental implants are viable solution to missing or lost teeth. However, with the costs of dental implants being high, you just don’t want to know that implant can fail and implant restoration process can take you through the whole costly procedure once again only because proper methodologies were not used the first time around.
Unfortunately, dental implant failure is a common occurrence when treatment standards are compromised. Today’s advanced dental technologies have enabled dentists to consistently decrease the risk of dental implant failure; however, we still observe a 2% dental implant failure rate. Dental implant success is related to operator skill, quality and quantity of the bone available at the site, and the patient's oral hygiene but the most important factor is primary implant stability. Please be advised that this isn't to criticize any particular dentist. Dealing with human body, it is difficult to guarantee a 100% success as many variables may contribute to achieve a specific outcome. This fact, however, does not suggest that you could settle for sub-standard work or low quality cheap dental implants. It simply means that dental implant could also fail because of some factors that were unfortunately not-known or not-discovered by the dentist at the time of placement.
Types of Dental Implant Failure
Dental implants failure is simply an implant that fails to fully integrate; it could be placed into 4 different categories:
• Infections – Dental implant infection is the number one reason that an implant is rejected by the body and the procedure is deemed a failure. Implant fixtures need precise fitting and improper fitting can result in infections. Patients’ oral hygiene could be a contributor to implant infection development. In most cases, medication alone is not enough to control and treat the infection. Instead, the dentist will often need to remove the implant and do the procedure again after cleaning the infection out.
• Loose implants – Loose dental implants could be a result of: substandard fixtures, premature placements, lack of solid bone support…, to name a few. In most cases the implant is considered a failure.
• Nerve impairment – Inadequate imaging technologies such as 2D imaging can result in placement of fixtures in positions where they irritate the nerves which will cause nerve reactions such as persistent numbness, tingling, or pain.
• Puncture of other cavities – Again, lack of experience or inadequate imaging technologies have resulted in a number of dental implants being placed in sinus cavities, the mandibular lingual space, and even the nose. You can only imagine the pain and discomfort associated with such placements.
To learn more about implant failures, please read part2 of this article on causes of dental implant failure.
If you are suffering from dental implant failure, consider seeing an experienced Implant Specialist such as Dr. Elyassian. Even if you are in another state, when you add the costs and time involved in failed treatment, and add that to the cost of what you might spend in the future if your treatment isn't done correctly, a couple hundred dollars for your time/travel would certainly worth the assurance that your treatment will be done correctly this time. Many people fly in to Orange County, CA to see Dr Elyassian from other states, and his office helps with guest accommodations at local nearby hotels.
Dr. Elyassian has yet to see a case of dental implant failure that he has not been able to rescue. Please see the about Dr. Elyassian’s page and his awards page for more information about his reputation and credentials.

Treating gum disease may be a better alternative to Dental implants, a new study suggests. Dental implants are reliable replacements for teeth that are already missing, but they’re not always the best choice for diseased teeth, a new study indicates.
Treat gum disease and preserve the tooth instead of rushing to extraction and Dental implants
Dental implants are reliable replacements for teeth that are already missing, but they’re not always the best choice for diseased teeth, a new study indicates.
Instead, attempts to save the tooth with treatment, especially in cases of gum or periodontal disease, should sometimes be tried first, the lead researcher said. And although the study did not address expense, dental implantsare not cheap, costing roughly $3,500 for the complete treatment. ”Preserving teeth by proper periodontal treatment and a careful and frequent maintenance program will probably give the same, and even better, results for the long run,” said study co-author Dr. Liran Levin, an assistant professor of periodontology at the Israel Institute of Technology and a visiting assistant professor at the Harvard School of Dental Medicine in Boston.
He reviewed 19 published studies that looked at either implant survival rates or tooth survival rates over at least 15 years. The results are published in the October issue of the Journal of the American Dental Association.
Levin found that about 4 percent to 13 percent of teeth not implanted were lost. None to 33 percent of implants were lost. According to the U.S. National Institutes of Health, an implant is viewed as successful if it is functional for five years in 75 percent of cases.
“This is one of the first reviews comparing the long-term survival of dental implants as opposed to properly treated and maintained teeth,” Levin said.
Dental implants are one of the biggest advances in dentistry in the past 40 years, according to the American Dental Association website. The procedure usually requires three phases once the natural tooth is extracted or missing. First, the dentist surgically places the implant — a post-like device that serves as an anchor — into the jawbone. The bone around the implant is allowed to heal. An artificial tooth is made to fit over the implants.
Based on the results of the review, Levin said he tells patients: “When advised to extract a tooth, don’t rush into that. Try to seek a second opinion, be sure to treat the disease [if any] and eliminate it before going through dental implantation. Always ask about the possibility not to extract.”
In some cases, of course, implants are preferred, Levin said. “There are several cases that usually require tooth extraction and are unsalvageable.” For instance, he said, teeth with vertical root fractures or other structural problems.
However, some dentists are over-recommending implants, he said. “This might result from their belief that dental implants are better, which was proved wrong in our review, or from other reasons,” he said.
Dr. Edmond Hewlett, a spokesperson for the American Dental Association and a professor of restorative dentistry at the University of California, Los Angeles School of Dentistry, said he doesn’t get the sense that dentists are over-recommending implants.
The study, however, makes an important point, he said. “We can’t assume an implant is going to be better than keeping the tooth,” Hewlett said. “A lot of times keeping the tooth and nursing it along may actually be a better option, all things considered.”
If a patient has gum disease, for instance, and the tooth is wiggling a bit, a patient may want to undergo periodontal treatment (such as gum surgery) and allow three to six months to see if the tooth responds, he said.
Some teeth, he agreed, are so damaged it would be difficult to treat them and implants are the best solution.
In the United States the cost for an implant –and the restorative crown that goes over it — ranges greatly, but can be about $3,500. Treatments for saving teeth vary greatly, depending on what procedures are needed.
Insurance coverage differs, too, with extraction typically included, while coverage for the dental implants can range widely.
