5 Reasons for dental implants failure
Dental implants are prosthetics that are implanted into the jawbone surgically and allowed to fuse with the dental tissues so that they accept the crowns and bridges made to replace lost teeth.
Dental implants are placed in the jawbone where they fuse with the tissues of the jawbone. When the metal screw becomes totally fused, it becomes strong enough to support the artificial teeth that are mounted on them.
How do they work?
Dental implants become part of the jawbone with the tissues that have grown around it allowing it to become one with the bone. This process of tissues growing around the metal screw is called osseointegration. This process allows the dental implants to bond permanently and allows the load and pressure of artificial teeth and bridges which will be placed on them subsequently. The process of osseointegration has to be completed before further prosthetics are mounted on the dental implants, otherwise the load will not be borne by the surrounding jawbone making it come loose with pressure and weight.
Why do dental implants fail?
It is not common for dental implants to fail. It does fail in rare cases though.
While all care is taken and best techniques used to put the implants in, sometimes they fail due to various reasons least of which is fault on the part of your dental surgeon.
Two main reasons of dental implant failures are Peri-implantitis and failed osseointegration.
What is peri-implantitis?
Peri-implantitis is a gum disease. The gums get infected because of bacteria and the jawbone gets damaged. When the bone gets damaged, the tissues which were grown around the implant get infected and loosen the grip they had over the implant. When the tissues give way to infection, the implant gets loosened and the prosthetic it was supporting comes unattached as a result. Peri-implantitis is caused by improper oral hygiene. Plaque gets built up because of lack of regular brushing. Food particles and remnants of food stuck between the teeth help the bacteria to feed on them. The bacterial activity produces acid as a result, and this acid eats away the enamel of the teeth. When enamel is eroded, the jawbone gets infected and this infection affects the tissues that were built around the dental implant.
When the jawbone does not grow around the dental implant totally, the implant is not securely held in its place. The failure of osseointegration is related to the quality of the jawbone. The quality of the jawbone depends on many factors. For example, if the patient smokes, it affects the bonding quality. When the patient has poor bone quality then the dental surgeon needs to graft the bone with healthier bone. This piece of bone should be allowed to bond with the jaw bone and then it will grow tissues around it. When the tissues do not grow around it in enough quantity the osseointegration fails and the implant cannot hold on its own making the crown or bridge topple.
Failure of implants in early stages
When proper procedures and protocols are not followed, the dental implants fail in early stages of the procedure which can happen within 4 months. The surgeon has to use proper tools and techniques. Sometimes even experienced surgeons may see implant failure in patients, because of lack of osseointegration.
There are many reasons when implants fail during early stages.
Health of the patient is very important for proper osseointegration and healing process of the surgery. When the patient has health problems, the procedure has more chances of failure.
When the implant is made to shift or moved, even during the healing period, the proper integration cannot be completed and the implant comes loose.
If for whatever reason, the supply of blood is disrupted to the implanted area, the implant does not get to be surrounded by bone tissue and it fails to support the crowns or bridges on top. Implants need a good many months to develop bone tissues around it. When the procedure is hurried along, the integration fails.
Long term failure
The more details you give your dentist, the better chance you have for longer lasting implants. Because your physical health very important for the implants to succeed in the long run.
Many dental implants start to fail after a good many years. The reasons vary.
The responsibility of the surgeon plays an important role in success of implants.
The most common reason for implant failure after a few years is the physical condition of the patient. As the age advances, the patient may develop diabetes, which affects the tissues that are bonded with the implant. Smoking too affects the tissues in which bonding suffer.
Certain medicines taken for cancer also prove to be detrimental for implant bonding.
There are people who suffer from psychological disorders like depression. The drugs used to control these disorders may interfere in the osseointegration of implants cause them to get loosened.
Like all the other dental treatments, the success of dental implants depends largely on oral hygiene routine followed by the patients. Regular brushing and flossing is extremely important to keep the mouth clean and infections at bay.
During the procedure also it is vital to keep in touch with your dentist and ask him about anything that worries you.
Enough time should be given for the process of osseointegration so that the implant can get well integrated in the jaw bone. Do not hurry to get implants done before the jawbone is ready.
It is advisable to get a good recommendation for the good surgeon as this procedure needs expertise as well as patience on the part of the surgeon to succeed.
Since you are spending a good amount of time and money on the project, it is absolutely worth every penny to listen to your dentist’s advice.
Look after rest of your body apart from oral hygiene as the entire health of your total self will guarantee the success of implants.
