Problems with snap in dentures vs. permanent dentures

More about snap on dentures

Snap-in dentures, also known as implant-supported dentures or overdentures, have become an increasingly popular alternative to traditional dentures. These dentures are designed to snap onto dental implants that have been surgically placed into the jawbone.

The use of dental implants to support dentures has been around for many years, but the concept behind snap-in dentures has evolved to improve their fit, comfort, and overall success.

The history of snap-in dentures can be traced back to the 1970s when dental implants were first introduced as a way to anchor dentures in place.

In pioneer treatments, dental implants were typically placed into the jawbone and then connected to the denture via a bar that spanned the implants. This bar served as a stable foundation for the denture to rest on, but it could also cause discomfort and irritation to the gums and other soft tissues.

Over time, the technology behind implant-supported dentures improved, leading to the development of snap-in dentures. Instead of a single bar, these dentures are connected to the implants via a series of snaps or attachments.

This design allows for a more secure fit, better distribution of pressure, and greater comfort for the patient.

Problems with snap-in dentures

Despite these improvements, there are still some problems associated with snap-in dentures:

1. Less durable than permanent, all-on-4 implants  

One of the main issues is that the fit of the denture can be affected by changes in the jawbone over time. When teeth are missing, the jawbone will begin to deteriorate, which can cause the denture to become loose and uncomfortable. This problem can be addressed through regular maintenance and adjustments to the denture, but it can still be a source of frustration for some patients.

2. More expensive than conventional dentures

Another potential problem with snap-in dentures is that they can be more expensive than traditional dentures. The cost of dental implants and the surgical procedure required to place them can add significantly to the overall cost of treatment. However, many patients find that the added comfort and stability of snap-in dentures are worth the investment.

3. Require special cleaning process

All dentures require regular cleaning to maintain good oral hygiene and prevent the accumulation of bacteria and plaque in the mouth. 

For snap-in dentures, they should be removed from the mouth and cleaned thoroughly with a soft-bristled brush and denture cleaning solution or mild soap and water. It is important to avoid using harsh abrasives or stiff brushes, as these can damage the dentures.

In addition to regular maintenance at home, it is also important to have snap-in dentures professionally cleaned and checked by a dentist at least once a year to ensure that they are in good condition and fitting properly.

4. Must be removed when going to bed

Although overdentures feel more stable in the mouth, it is generally recommended that you remove them before going to bed. This is because wearing dentures for extended periods without a break can cause discomfort, irritation, and even inflammation of the gums. 

Removing dentures at night also allows the gums to rest and recover from the pressure of wearing them during the day.

Additionally, removing dentures at night can help prevent the buildup of bacteria and plaque, which can cause bad breath and other oral health problems. Therefore, it is best to follow the advice of your dentist and remove your snap-in dentures before going to bed.

5. Long recovery time

With snap-on dentures, you typically need a minimum of two implants to support the denture, but some patients may require more depending on the amount of support needed. 

Following implant placement, you will have to wear a temporary denture and maintain a soft diet for the next 3 to 6 months as you wait for the implants to fuse with the bone. Then abutment will be placed to support your overdenture.

It’s important to note that the process of fitting and attaching snap-on dentures may also involve some adjustments and follow-up appointments with the dentist, which can also impact recovery time.

Permanent, all-on-4 dentures

If you’re not satisfied with the stability offered by snap-in dentures, you can opt for all-on-4 treatment, also known as “Teeth in a Day, whereby the dentures are permanently attached to four implants (instead of 2 as is typical with overdentures).

Unlike the former, which use a specialized attachment system that makes it possible to remove them for cleaning, all-on-4 dentures can never be removed, except in the dentist’s office if absolutely necessary.

This treatment involves the placement of four dental implants strategically in the jawbone, which serve as anchors for the prosthesis. The denture is then fixed to the implants and is not removable by the patient. All-on-4 permanent dentures are designed to look and function like natural teeth, and they provide a long-term solution for tooth loss.
