Partial Dentures: Partial dentures can either be made with a plastic base or a metal framework that supports the number of teeth that need to be replaced. It is held in the mouth by using clasps and rests that are carefully adapted around the natural teeth. The partial denture that uses a metal framework is the traditional design, due to the rigidity and strength of the metal. Plastic partial dentures have normally been used as emergency or temporary replacements of missing teeth, allowing the gums and bone to heal before a definitive restorative solution is obtained. Recently, however, various materials such as Valplast have been developed to provide durable, flexible alternatives in certain situations.
Daily cleaning of dentures is recommended. Plaque and tartar can build up on false teeth, just as they do on natural teeth.[24] Cleaning can be done using chemical or mechanical denture cleaners. Dentures should not be worn continuously, but rather left out of the mouth during sleep.[25] This is to give the tissues a chance to recover, and wearing dentures at night is likened to sleeping in shoes. The main risk is development of fungal infection, especially denture-related stomatitis. Dentures should also be removed while smoking, as the heat can damage the denture acrylic and overheated acrylic can burn the soft tissues.
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
