Types of Dentures
Dentures are removable substitutes for missing teeth and the surrounding tissues. There are basically two types of dentures: 1. Partial Dentures 2. Complete Dentures
These are dentures that are used when some teeth are lost but there are still a number of natural teeth remaining. When there is a tooth missing, the natural teeth shift from their original position to try and fill in the empty space. Partial dentures fill in the gaps that are created by the missing teeth.
This helps maintain the alignment as well as the function of natural teeth. A partial denture consists of a replacement tooth that is attached to a gum-colored base. This is held securely in the mouth by a clasp that is made either of plastic or of a special metal alloy. The clasp wraps around the neighboring natural teeth to keep the denture in place and can be removed whenever necessary so that the remaining natural teeth can be cleaned and brushed regularly. A precision partial denture is a more natural-looking prosthetic. It can also be removed but instead of clasps it is attached internally to the adjacent crowns.
Complete dentures are used when all the teeth are missing and there are no natural teeth that can be used to support the bridge. There are two categories of complete dentures: • Conventional Dentures: A conventional denture is usually made after the tooth has been extracted and the gum tissue begins to heal. It is then ready to be positioned in the mouth about 8 to 12 weeks after the extraction of the tooth. • Immediate Dentures: An immediate denture made in advance removing the bad teeth and can be placed in the mouth immediately. The advantage of immediate dentures over the conventional version is that you do not have to live without teeth during the healing period. However, the disadvantage is that they require more adjustments and/or relines to fit properly, especially during the healing process as gums and bones tend to shrink after the tooth removal. Immediate dentures are usually considered as a transitional stage until healing is complete. Then a new denture is recommended.
