Dentures are artificial teeth and gums that are fabricated by impressions and another measurement in the oral cavity so as to replace missing teeth and help the patient in chewing, speaking and maintain the facial appearance. Dentures can be either partial or complete depending on the missing teeth.
Dentures are usually of removable types but with latest techniques available they can be either semi-fixed or totally fixed using implants. Minimum of two implants are required to support complete dentures and it is called as implant-supported over denture. If good amount of bone is available 4 to 6 implants can be placed to give a complete fixed denture.
Partial dentures replace few missing teeth and are made up of either acrylic or a combination of acrylic and metal which are called cast partial dentures.
