In addition to conventional dentures which rely on suction and tongue and cheek muscles for retention, implant supported dentures can be made which are patient removable and non- removable designs.  Patient-removable designs still have the pink lip supporting flanges and provide the easiest cleaning.  Non removable denture designs have abbreviated pink flanges to provide for oral hygiene access.  Both types of implant dentures feature improved speech and chewing ability over conventional dentures.
