It is not very often that you hear about an unsuccessful dental implant procedure. Rejections are generally avoidable because of the screening process, modern techniques, technology and craftsmanship that go into this procedure. However, there are times when this happens and patients do need to be prepared for this possibility.
When patients are missing teeth, dental implants are the first choice to replace them. A titanium post will be screwed into the bone which will fuse to it during the healing process. The abutment will then be attached to the post and the crown anchors everything to create a natural feeling tooth which stays in place.
The reason for rejection is not easy to determine and they are not cut and dry. There are many reasons for why a body could reject dental implants, but you might not be able to determine which one is at play. Over the years, dental professionals have come up with a number of theories that could explain implant rejection.
Is Improper Osseointegration The Cause?
The entire dental implant procedure relied on the process of osseointegration for it to be successful. There are times when scar tissue will form around the implant instead of the needed bone and this leaves the post insecure and loose. This can lead to breaking and chipping of the other teeth in the mouth, cuts to the gums, tongue or cheeks and could result in the implant falling out.
One of the reasons why this might happen is that bacteria was present at the time of installation. The body will view the post as a foreign contaminant and send out white blood cells which will attack the implant and the bacteria. This attack is what results in the body rejecting the implant.
Could Lifestyle Be Behind The Rejection?
Before dentists agree to dental implants, an assessment of the patient will be done to ensure that they are a viable candidate. Nicotine and extensive alcohol consumption will generally cause dentists to reject calls for implants. However, if the patient partakes of these activities after the treatment anyway, it could result in the body rejecting the implant. This is due to the fact that the mouth is not given enough time to heal correctly. Certain lifestyle choices will need to be eliminated if dental implants are to be successful.
Is The Patient Allergic To Titanium?
Most dental implant posts will be made of titanium because of the strength and the fact that there are not many people who are allergic to it. However, there are some people who have a titanium allergy and if you are one of these people you need to ask the dentist to use a zirconia implant instead. This is a ceramic material which is non-corrosive and effective when it comes to replacing a tooth.
The typical symptoms of titanium allergies will be skin rash and fatigue. While this is not a common occurrence it is possible that it behind the rejection of an implant.
