How Dentures Are Made
Dentures consist of a flesh-colored base and the synthetic teeth attached to it. Today, both components are made of a type of acrylic. The artificial teeth are typically made of acrylic resin, which closely approximates the appearance of real teeth.
Once the decision is made to proceed with dentures, the patient will make an appointment for the impression. The dentist will put a tray with a thick paste into the patient's mouth to take impressions of the upper and lower teeth. This process usually takes about 20 seconds for each impression. The dentist may offer to apply a numbing agent to the palate beforehand to minimize discomfort.
Afterward, the impressions are used to make a plaster model of the mouth. The dental lab technician then uses wax to attach the teeth. The wax is shaped and trimmed according to the patient's gum shape.
Then the wax shape with attached teeth is placed in a container, sometimes called a flask. Dental stone or plaster is poured around to hold it. The wax is then boiled out, leaving a molding in the shape of the gums, and the acrylic material for the dentures' base is poured in.
The denture is removed from the container, trimmed and polished. At this point, the patient will have the first fitting. While some people may find their dentures fit properly right away, most need to have a few adjustments done for optimal comfort.
It is normal to need several fitting appointments before the dentures fit the way they should. Patients should not hesitate to let the dentist know if something feels wrong. What may seem like a trivial amount of discomfort during fitting can seriously interfere with your quality of life, later on, so be sure to speak up.
Types of Dentures
There are several basic types of dentures. The right option for you can depend on several factors, which Jared M. Smith DMD can discuss with you. Choosing an option that works for you can help you get the most out of the dentures.
Dentures can be full or partial. A full set can be necessary for patients who are missing all their teeth. In this case, impressions will be taken of the gums and the teeth made to maintain the proportions and distances similar to the real teeth. A partial set can be an option if the patient still has several teeth in good condition remaining.
Additionally, there are also fully removable and bridge-supported dentures. Removable dentures are what most people picture: the base that sits on the gums with attached teeth. They can be easily taken out. While this option is typically more affordable, removable dentures may need several adjustments over the years as the mouth's shape changes.
Bridge-supported dentures are also removable but do not have a base. They are clipped on to four or six dental implants. These implants are small titanium posts that are surgically inserted into the jawbone. Eventually, the implants fuse with the bone.
Due to the implants, bridge-supported dentures tend to be more costly than other options. They also involve minor surgery. However, many people find they feel more secure and are more comfortable because they do not need a base. The implant procedure can also reduce future bone loss, which can be familiar with missing teeth.
Not all patients are good candidates for fixed dentures. Those who already suffer extensive bone loss may not have enough bone to support the implants. Some other health concerns can also prevent implants from being a good option.
