Every tooth in your mouth is vital to maintaining proper alignment, and spaces left behind by one or more missing teeth can have an effect on your bite, speech, smile, and face shape. Missing teeth can cause your remaining teeth to shift and cause problems with your bite. To preserve your oral health and dental hygiene, you should weigh your options when it comes to tooth replacement treatments and choose the procedure that meets your needs.
Conventional dentures are installed after the last teeth are removed, to allow for healing (typically six to eight weeks). There are typically separate appointments for impressions and measurements; checking a "try-in" model for fit; inserting and adjusting the final denture; and follow-up appointments to check comfort and function. Immediate (same-day) dentures are made in advance and inserted when the teeth are pulled. The University of Iowa provides an overview of immediate dentures[2] and a California dentist has a immediate denture video[3] .
The different types of complete dentures include Conventional, Immediate and Implant-retained. Conventional Dentures which are applied after the teeth are extracted and the gums are allowed to heal – takes around 8-12 weeks. Prior to the fitting of the Conventional Dentures and the interim healing period, the dentist would normally place a pre-fabricated Immediate Denture over the gums to protect the area while the patient waits for the Full Denture to be made at a dental lab.
Full or partial dentures consist of a gum-colored base made of plastic resin, which fits over the remaining alveolar (bone) ridge that formerly held the teeth. The prosthetic teeth projecting from the base are designed to look and function just like your natural teeth. Dentures are held in place primarily by the suctioning effect of their close fit against the alveolar ridges — that's why it's so important that they are fitted properly. The upper denture also gets extra support from the large surface area of the roof of the mouth (palate), which generally makes it extremely stable.
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.
