Denture Care & Repair

Indications for Complete Dentures

Complete dentures are full-coverage oral prosthetic devices that replace a complete arch of missing teeth. The following are indications for this type of dental prosthesis:

A full arch of missing teeth

Dental implants that have been deemed inappropriate by patient and/or doctor because of financial constraints, a medically compromised status that contraindicates surgery, or inevitable damage to vital structures such as maxillary sinuses, nerves, and vessels

Intraoral cancer that has caused a loss of gross intraoral tissue, resulting in an edentulous dental arch; the complete denture prosthesis would then not only replace teeth but also fill in the portion of missing tissue (eg, nasopharynx, hard palate)

An edentulous maxillary ridge.

Maxillary complete denture used to restore the upper ridge and a mandibular partial cast denture placed to restore mandibular partial edentulous regions.

Types of Complete Dentures

Conventional complete dentures

These are dentures that are fabricated using acrylic resin and that rely on the alveolar ridge, saliva, and other supporting structures for retention.

Immediate complete dentures

These are dentures usually delivered immediately after all remaining teeth of a dental arch are removed. During the healing process, this denture helps to confine the remodeling of the underlying ridge to the interior of the denture. Ordinarily, this type of prosthesis must be relined periodically as the underlying tissues heal and remodel. Usually, after 6 months, a conventional complete denture is indicated (ie, a new denture).

Overdentures

These are dentures that fit over usually two or more roots that have been salvaged and stabilized. These dentures can also fit over dental implants that have been placed. With overdentures, locator attachments are sometimes secured within the remaining roots or within placed dental implants, and these components are known to improve retention. Roots and dental implants help to preserve bone, and the added retention is known to be greater than conventional complete dentures alone.

Partial Dentures

A removable partial denture usually consists of replacement teeth attached to a pink or gum-colored plastic base, which is sometimes 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.
