Can Dental Implants be removed? – Ask a Dentist in Spring Texas
Dental Implants are the most famous in the world of restorative dentistry today. One of the main reasons why they are widely preferred by many and their popularity is growing vastly is the fact that they have a high success rate and are highly durable as compared to other types of restorative dentistry procedures. However, there are a considerable number of failure cases that emerge with the dental implants that warrant their removal. Dentists in Spring, Texas from Vita Dental are experienced in dental implantology and shed more light on the removal of dental implants through this post.
Dental Implants can be removed in the event that they fail. There are a number of reasons for failure of dental implants. Some of these reasons include:
• Failed Osseointegration
Osseointegration is the process by which the dental implant fusses into the jawbone of the patient creating a structural connection. The process takes up to several months after the implant has been positioned. Sometimes the implant fails to fuse into the jawbone properly making the implant lose. One can tell that their implant has not fused properly when it feels like it wants falls off or when there are signs of bone loss. The main reasons for this are the implant was not being positioned properly, the patient having insufficient bone density, trauma, damage to surrounding tissue, and if the implant is fractured.
• Allergic reactions
These days, other titanium alloys have been discovered and are being used to make the implants. While the cases are quite rare to come across, some people may be allergic to these titanium alloys causing an allergic reaction and, consequently, failure of the implant.
This is one of the main causes of dental implant failure. The cause of the infection could originate from the surgical procedure, or it could develop after the procedure. The infection usually affects the bone and tissue surrounding the implant. This condition can be treated in some cases, but in most cases, the implant usually needs to be removed. The most vulnerable groups of people for this condition are smokers, those with diabetes and those whose oral hygiene standards are low.
• Damaged nerves and tissue
Damage to the nerves and tissues surrounding the implant also causes the implant to fail. Most of these cases stem from mistakes made by the implant specialist when inserting the implant. The damage to the nerve and tissues could be temporary or permanent, but this calls for the implant to be removed.
Other reasons for dental failure include sinus problem, overloading and implant rejection itself.
Dental Implant Removal
There are a number of ways used to remove failed dental implants. The first approach involves the use of a special instrument for cutting called the trough bar. This tool is used to cut the bone structure surrounding the implant. Only half of an inch or an inch of the bone can be removed. The cutting of the bone loosens the implant making it easy to come off. After the implant has come off, the area is cleaned thoroughly to get rid of any bacteria and then evaluated for bone grafting. Bone grafting is normally used to restore the bone structure and any defects in it.
This procedure gets the job done, but it is not the most effective as it generates a lot of heat that affects the vitality of the bone. Also, the cutting of the bone structure could potentially generate a larger defect than what initially existed.
The other procedure is fairly new and less invasive. It uses special instruments that facilitate the gentle removal of the implant from the bone without exposing the bone and the surrounding tissues to further damage. The procedure involves the fixing of an adapter to the implant then engaging a torque instrument to it. The implant is then de-bonded using a high-reverse torque. In cases where the implant has been tightly fixated into the jawbone, a few millimeters of the bone may need to be cut.
This procedure is much safer and prevents the removal of any vital bone.
What next after dental implant removal?
The actions to be taken after a dental implant has been removed depend on the circumstances, biological reasons and anatomical considerations. There are a number of options for one to take and some include:
• Replacing the removed implant with another implant
In case the site is free of infections, clean and has enough bone structure to support an implant, then one can immediately replace the removed implant with a new one.
• Bone grafting
For patents who have no sufficient bone structure to support a new implant or if the bone structure was damaged when the initial implant was being removed, bone grafting can be done to allow the bone structure to heal. This usually takes between 4 to 6 months. After the bone structure is fully restored, that is when you can get another implant inserted.
While cases of dental implant failure are relatively few, cases often arise from dental implant failures. For residents of Spring, Texas, Vita Dental provides reliable treatment to ensure you get your tooth restored.
