Complete dentures can be either "conventional" or "immediate." Made after the teeth have been removed and the gum tissue has begun to heal, a conventional denture is ready for placement in the mouth about four to six weeks after the teeth have been removed.
Unlike conventional dentures, immediate dentures are made in advance and can be positioned as soon as the teeth are removed. As a result, the wearer does not have to be without teeth during the healing period. However, bones and gums shrink over time, especially during the healing period following tooth removal. Therefore a disadvantage of immediate dentures compared with conventional dentures is that they require more adjustments to fit properly during the healing process and generally should only be considered a temporary solution until conventional dentures can be made.
A removable partial denture or bridge usually consists of replacement teeth attached to a pink or gum-colored plastic base, which is connected by metal framework that holds the denture in place in the mouth. Partial dentures are used when one or more natural teeth remain in the upper or lower jaw. Not only does a partial denture fill in the spaces created by missing teeth, it prevents other teeth from changing position. A precision partial denture is removable and has internal attachments rather than clasps that attach to the adjacent crowns. This is a more natural-looking appliance.
For patients who have missing teeth, partial dentures have long been a popular restoration option. A removable approach to replacing lost teeth, partial dentures have typically been made with metal clasps attached to a gum-colored base. However, metal clasps aren’t always an ideal option for certain patients, prompting the creation of metal-free, flexible partial dentures.
Flexible partials are an alternative to both metal-based dentures and fixed restoration options, such as fixed dental bridges. These cutting-edge prostheses are removable, aesthetically pleasing, and are custom-made to fit each patient’s mouth. Because flexible dentures are completely metal free, they are an idea treatment for patients with metal allergies.
