What are the most common causes of failure of dental implants?

Peri-implantitis, an infection in the jaw around dental implants, is the most frequent cause of dental implant failure. Although implants cannot get cavities, they might still get gum disease that is exclusive to implants. Although there are many potential causes for dental implants to fail, infections and bone loss are the most frequent and easily avoidable. The success of an implant treatment depends on a variety of variables, but certain behaviors and health issues can make the implant more likely to wobble.

Gum disease and bruxism, or teeth grinding, can harm an implant that is healing, and conditions like osteoporosis, which affect bone density and strength, can make it challenging to anchor the implant screw. This is why it's important to choose trusted professionals like Compton And Broomhead Dental Center to ensure the proper placement and care of your dental implants, even in the presence of these challenges. Since radiation therapy can occasionally prevent bone from mending, ongoing cancer treatment may also lead to the removal of an implant. Since the body does not produce antibody-antigen type responses similar to those seen after organ transplants, dental implant failure is never the consequence of the body rejecting the implant. No matter where you decide to have your dental implants placed, it's crucial that you are aware of the dangers and that the dentist you select has the training and experience necessary to keep those risks to a minimum while still making a worthwhile investment in your dental health.

In general, occlusal stress, nerve injury, and poor oral hygiene are the leading reasons of dental implant failure. A dental implant's failure could also be caused by a number of additional causes. These include peri-implantitis, low bone quality, and unsuccessful osseointegration.


Peri-implant disease affects about one-third of all dental implants. It is brought on by tissue around the implant becoming inflamed. The implant may not function due to the resultant harm to the bone and gums.

The properties of the implant surface, the kind of implant, the morphology of the abutment, and the degree of roughness all affect the etiology of peri-implantitis. Despite the fact that bacterial infections are the primary cause of the infection, other factors such as in loco infections, stress-related implant failure, and allergic reactions may also play a role in its progression. An important factor in preventing peri-implant disease is infection management. This involves keeping the mouth clean and lowering the risk of irritation by placing the implant in an occlusive environment and inserting the MI with sterile tools.

Both bacterial eradication and abutment regeneration are necessary for the treatment of peri-implant illness. Antibiotics can be used to stop the inflammatory process and get rid of the infection-causing germs. The implant may need to be surgically removed if the peri-implant infection is severe.

Failed osseointegration

The titanium implant is secured to the jaw bone during osseointegration. Weeks or months are typically needed for this process. The dental implant will not work properly if this process is not finished. It may occur for a variety of causes. It might need to be taken out in severe circumstances. Fortunately, there are solutions to the issue. Inadequate implant location, infection, and general health are some of the main reasons why osseointegration fails. Peri-implanttitis, physical trauma, and heredity are additional factors. The swelling of the gums around a dental implant is referred to as peri-implantitis. It happens when oral bacteria assault the tissue surrounding the implant. This might harm the gums and bones. It might result in the loss of the supporting bone and failure of the dental implant if left untreated.

Poor oral hygiene

It's critical to take proper care of your teeth for both your health and the health of any dental implants you may have. Daily tooth brushing and flossing are required, and you should schedule checkup appointments with your dentist on a regular basis. Artificial tooth roots known as dental implants are attached into the jawbone surgically. They offer a durable tooth replacement that mimics real teeth in both appearance and functionality. If you neglect your implant, though, it could fail and you might end up losing your teeth. An infection of the gums called peri-implantitis is one of the most frequent causes of a failed implant. When bacteria gather at the implant's base, this illness develops. It may cause bone loss and harm the implant's base of support.

Occlusal overload

The patient's biting power is an important factor in the design and placement of dental implants. In order to select the ideal implant size and location, a quantitative measurement of the maximum jaw biting force can be used. Dental implants may break under the high stresses produced by the patient's mouth, losing osseointegration and peri-implant bone in the process. The increased bite force also affects the parameters used in physiologic therapy planning.

With careful treatment planning, occlusal overload can be prevented. An implant-supported prosthesis' optimal occlusion minimizes occlusal load within physiologic ranges, reduces stress on the implant system, and preserves the long-term stability of marginal bone. A gradual bone loading idea can be used to optimize the occlusion of an implant-supported prosthesis. In order to offer osseous support, several implants may be positioned, depending on the patient's bone densities.

Nerve damage

A dentist operating on a dental implant may injure the inferior alveolar nerve (IAC), a neurovascular bundle running through the center of the jawbone. This could result in ongoing discomfort and incapacity. The lingual, opthalamic, and maxillary divisions of the IAC are its three main subgroups. A rotary tool or other sharp equipment used by a dentist could cause damage to the lingual nerve. Additionally, microorganisms that were present during the procedure can cause an infection.

Additionally, a dentist has the option of screwing the implant all the way into the nerve canal. This may result in long-term nerve injury and an elevated likelihood of failure. The requirement for sufficient bone volume to sustain the implant is another crucial element of a successful dental implant. This is especially true in the high-risk area of the posterior mandible.

As poor oral hygiene is a significant reason for dental implant failure, be sure to take good care of your teeth as well. Numerous factors, such as the patient's overall health, the quality of post-procedure care, and the dentist's ability and competency, might cause a dental implant to fail. Tooth grinding, an allergy to the materials used, shoddy dental impressions, infection, nerve damage, implant movement, issues with the underlying jaws, and numerous pharmaceutical diseases are causes of dental implant failure. A difficult, multi-stage treatment like dental implant surgery leaves little opportunity for error, no matter how slight.

Late implant failures typically come from pressure being exerted on the prosthetic tooth as well as other health issues. They might advise you to choose an alternative approach, such as dental bridges, partial or complete dentures. Every time something new is introduced into your body, according to the Australian Dental Association, there is a chance for negative side effects. Depending on where in the mouth the implant is placed, smoking can raise the chance of dental implant failure.

Dental implants and All on 4 can provide you a beautiful, natural smile while enhancing your quality of life, whether you need to replace one tooth or several teeth. Teeth grinding, also referred to as "bruxism," can pose a threat to a dental implant's success. Patients frequently come to Spyrakis to have implants and failed dental procedures done by other dentists fixed. The best and healthiest way to replace missing or damaged teeth is now with dental implants.
