Dentures are artificial devices designed to look and function as if they are real gums and teeth. They are built for the following purpose:
Dentists are responsible for customizing dentures that will fit a patient’s mouth. Dentures are made to match the size, color, proportion, and appearance of a patient’s existing teeth.
Dentures used in the past were created from plastic or porcelain. Currently, most modern dentures are made from hard resin. Compared to real teeth, the materials that make up dentures are considered to be too fragile that they could crack or chip if not properly cared for. As a result, dentures may need to be replaced approximately every 5 years. The artificial gum line found on dentures is made from flexible polymer that snugly suits the natural gum line of the mouth.
The initial stages on making dentures require dentists to take impressions of the patient’s mouth.
Based on this impression, the dentist makes a plaster model. This model is then put on an articulator – a mechanical device that simulates the movements of the jaw joints. The dental technician attaches a patient’s chosen teeth with wax to the articulator.
The wax is then molded and carved according to the appearance of the patient’s gums. The dentures are then put in a flask where further plaster will be poured in - the goal of which is to retain the dentures’ shape. The flask is later put in boiling water to remove any melted wax.
Excess wax is rinsed off while the dental technician brushes a liquid separator on the plaster to avoid the acrylic from sticking on to it. Later on, the flask is injected with acrylic in order to cure and replace the wax.
Plaster mold is removed by the technician using laboratory tools. The dentures are immersed in an ultrasonic bath to further remove plaster remnants.
The trimming process is done to remove additional acrylic, while polishing is done using pumice.
Once done, the dentures are ready to be given to the dentist for the patient’s initial fitting.
There are many types of dentures. The following are basic dentures and their usage. Choose those which suit your needs, budget, and dental requirements.
When using dentures for the first time, expect to experience a few adjustments because the muscles of your tongue and cheeks are still trying to get used to the new “teeth”. To facilitate the adjustment process, do use a dental adhesive to allow your dentures to naturally fit your mouth.
It may also be normal to find yourself having more mouth saliva, as well as experience minor mouth irritation or soreness, Try not to worry as these issues naturally resolve themselves through time. However, if major issues persist and no improvements are seen, you might need to refer your problems to your dentist so you can have your dentures appropriately adjusted.
