A dental implant is basically an artificial tooth root that is used by dentists to support reinstatements which look like one tooth or a group of teeth. Practically all implants done today by dentists are very realistic and are matched up in colour perfectly to the surrounding teeth. Most of the implants are called root-form endosseous implants which mean they are put into the actual bone root. Before the root-form endosseous implants were used, the dentists used to use blade endosseous implants which were a piece of metal put in the bone and looked like a smooth blade
The dentists also used an implant called a subperiosteal, this is where the implants were attached to the patient with screws to the jaws. Dentists can also use implants to help support different types of prostheses like crowns bridges and dentures. Implants have a great success rate of over ninety percent but as most other procedures there are many things that can change and lower this rate of success.
Implants can inevitably fail and most of the time this will happen as a direct cause from smoking. Basically nicotine makes the oxygen flow to the bone slow right down regardless if you smoke or chew on tobacco. If you do not allow the oxygen to reach the bone then it will result in the implants being removed due to the amount of pain. If you have recently been on chemotherapy be aware this can also cause a problem with the bonding process of the bone and the implant. If the implant undergoes stress this can also cause your bone to reject it because the implant is made from titanium which means the body will believe it is an actual tooth but if moved slightly out of place then the bone will think it is just a foreign object and thus reject it.
If your teeth have been vacant for a long time then there may be a lack of blood flow to that specific area and by applying an implant the bone and jaw may not be able to supply enough blood thus causing it to reject the implant. After all these complications and even when all procedures and rules have been followed the implants can still fail for no reason at all. Allergies to titanium are rare however can cause problems so its important to have the tests to check for any allergies.
