Dentures have come a long way over the years and are a great option for patients who need to replace an entire arch of teeth. Dentures can go on one or both arches and there are a few different types that patients can take advantage of. A traditional denture is what most people think of when they think of dentures but implant over dentures are a better option for those who can endure implant placement surgery.
While a traditional denture is a great option for those who need it, they do not support bone health and can lead to bone deterioration which can cause dentures to become ill fitting and uncomfortable. Bone deterioration can also lead to changes in facial structure over time. Dental implants act as an artificial tooth root and help support bone health by stimulating bone regeneration and do not cause deterioration as traditional dentures do. Implants allow patients to get more wear from their denture which may need to be replaced eventually due to normal wear and tear as opposed to bone degeneration.
What is an implant overdenture?
An implant overdenture is a dental prosthesis that looks like a traditional denture but instead of being held in place with retention and suction, is held in place utilizing dental implants. Implants are a small screw generally made of titanium that is placed directly into the jawbone and provides a stable foundation for the denture. Implant overdentures are incredibly secure and allow the patient to speak and eat without discomfort and without worrying about their denture slipping.
There are two types of implant overdentures: an implant retained overdenture and an implant supported overdenture. The main difference between the two is that an implant retained overdenture is removable. Implant retained overdentures have a connecting bar that is secured onto the implants and the overdenture clips onto the bar. Implant supported overdentures cannot be removed by the patient and are screwed directly onto the implants.
Dental implants are placed by either an oral surgeon or a periodontist. The Doctor makes a small incision in the gum tissue where the implant will be placed and then drills a small hole into the bone. The implant is secured in place and the gum tissue is sutured up around the implant, leaving a small portion protruding above the gum tissue. The healing cap is placed over the implants and the patient is fitted with a temporary denture to wear while their implants heal. Once the implants are ready for restoration, the permanent overdenture is placed.
How long do implant overdentures last?
Implant overdentures can last a lifetime depending on your oral hygiene, overall health, and lifestyle. Dental implants are considered a permanent restoration and with proper care and maintenance, can easily last 20 years and beyond. The overdenture may need to be replaced every 15 to 20 years simply from daily wear and tear.
If you are missing a significant number of teeth or simply want a new dental prosthesis to replace a traditional denture, speak with your dentist to see if you are a candidate for an implant overdenture.
