Dentures are a great help to people who are missing their teeth. These dental appliances can improve speaking and food-chewing ability, as well as boost confidence. Modern dentistry offers several types of dentures, and the choice will depend on the personal preferences of a patient and the condition of their oral and general health. Please read our article to learn about the difference between traditional dentures and overdentures.
The Difference Between Traditional Dentures and Overdentures
The main difference between traditional dentures and overdentures is how they are attached to the mouth. Typically, traditional dentures can replace an entire arch of missing teeth. They sit on the gums and are supported by the roof of the mouth or lower jawbone ridge. This type of dental restoration consists of a base that resembles natural gums and a set of teeth. Traditional dentures are removable.
On the other hand, overdentures are usually supported by several dental implants—metal posts surgically inserted in the jawbone. In some cases, overdentures can be supported by remaining natural teeth. Similar to traditional dentures, this type of dental prosthetic is also removable. Overdentures consist of a gum-looking base and a set of dental crowns.
Pros of Traditional Dentures
Traditional dentures are typically less expensive than overdentures. The process of getting a set of traditional dentures is fast and can take just a couple of weeks. Also, every patient can get traditional dentures, as eligibility does not depend on the condition of the jawbone, unlike when it comes to implant-supported dentures. In addition, traditional dentures are relatively easy to clean.
Cons of Traditional Dentures
Traditional dentures are typically custom-made to fit the shape of your gums as snugly as possible. However, due to the way they are attached to the mouth, they can present some inconvenience and discomfort. Some patients might experience rubbing and soreness, or the dentures might move around in the mouth or slip when chewing food, causing pain.
Traditional dentures can offer only about 20% of the natural bite force, meaning that patients will have to adhere to a softer diet. Also, the fact that traditional dentures can be mobile in the mouth might cause difficulties speaking or various speech impediments, such as a lisp.
Pros of Overdentures
Overdentures that are supported by dental implants provide greater security and stability in the mouth compared to traditional dentures. They are much less likely to move and slip when chewing or speaking and offer up to 90% of natural bite force, allowing patients to enjoy a wider variety of foods. In addition, overdentures usually do not cover the pallet, meaning that a patient will be able to taste food better than with traditional dentures. Thus, comfort is one of the biggest advantages of overdentures.
Another advantage of implant-supported dentures is the prevention of bone resorption—the process of loss of density in the bone. It happens because the roots of the missing teeth do not stimulate the jawbone anymore. Thus, you can lose up to 20% of the bone density in the first year after the teeth are removed. Dental implants act similarly to the roots of the natural teeth and provide the necessary stimulation to the bone, preventing it from shrinking. This stimulation also helps prevent the sunken appearance of the face.
Cons of Overdentures
Overdentures will take longer than traditional dentures because the gums and jaw bone will have to heal sufficiently after dental implant placement before you can wear your dentures. Additionally, implant-supported overdentures will cost more than traditional dentures.
Unfortunately, not every patient is suitable for implant-supported overdentures. Dental implants can be successfully placed only if the jaw bone has enough density to support them. Patients who have been missing teeth for a long time might experience “shrinking” of the jaw bone.
However, in some cases, this condition can be improved by bone grafting, which prompts bone regeneration and prepares it for receiving dental implants. In addition, a patient’s general health plays a significant role in the success of dental implant surgery. Your body has to have sufficient healing and regenerative capacity for the jawbone to fuse with implants.
