Denture is a removable replacement for missing teeth and supporting tissues.
Two types of dentures are available – complete or partial dentures.
Complete dentures can be conventional or implant supported dentures.
Conventional dentures are made after the teeth are extracted and the gum tissue is left to heal for about 8 to 12 weeks. Upper Dentures covers the gums and roof of the mouth, allowing an entire set of false teeth to sit firmly. In the lower denture, the acrylic is made of horseshoe shape to avoid covering the tongue. The regular denture rubs against the gums especially lower jaw as they have nothing to hold them in place and are difficult to chew with. Also, the constant rubbing could cause sore spots and eventually the jawbone will shrink causing thin ridges.
Immediate dentures are also available, which are made immediately following extraction of teeth. Hence the wearer does not have to be without teeth during the healing period. However the gums and tissues shrink over a period of time, leading to ill fit of the existing denture. When patients insist on a temporary replacement following extraction, immediate dentures are made which are later replaced by conventional dentures.
Implant supported dentures The denture takes support from implants which are surgically placed into the jawbone at the level of the gums. An advantage over conventional is it prevents slippage especially in the lower jaw, making it more stable. Since the implants are embedded in the bone, the bone is less likely to resorb or shrink.
Partial dentures They are attached to natural teeth with the help of metal clasps that grip the teeth. Compared to conventional removable partial dentures, Cast partial dentures are available that consists of cast metal framework and artificial teeth set in acrylic resin. Cast partial dentures are more stronger, retentive and durable compared to the conventional ones.
