- The fabrication and placement of dentures is a form of removable prosthodontic treatment. Depending on the number of missing teeth being replaced, dentures are classified as:
- Partial Dentures, when they replace one or more missing teeth while natural teeth remain in the mouth.
- Full Dentures (Conventional Dentures), when they replace the entire dental arch (i.e. when the patient has no remaining teeth in a specific jaw).
Partial Dentures
Partial dentures replace teeth that have been lost in the upper or lower jaw and are supported by the remaining natural teeth on either side of the gap.
Retention of partial dentures may be achieved using the following methods:
Metal Clasps
Metal clasps are the simplest and least aesthetic option. One advantage is that the denture can be modified if additional teeth are lost in the future. However, the main drawback is that the clasps may be visible, resulting in a less aesthetic appearance.
Acrylic Clasps
Acrylic clasps are less visible than metal clasps, as they are usually gum-coloured. While they offer improved aesthetics, they are generally less durable compared to metal clasps.
Precision Attachments
Precision attachments replace clasps and provide maximum stability for partial dentures. Their use requires the existing teeth to be restored with a dental bridge incorporating small, specialized attachments, allowing the partial denture to securely “snap” into place.
Full Dentures (Conventional Dentures)
A full denture is a prosthetic restoration that replaces all teeth of a jaw. It is fabricated on an acrylic base, which may be reinforced with a metal framework when necessary. Acrylic or porcelain teeth are then mounted onto the base to restore function and appearance.
