Removable partial dentures are made to restore the appearance and function of your smile. This is done when you are missing some, but not all your teeth. Different types of partial dentures are available and may be recommended based on which teeth are missing. Cast frame (metal) dentures are stronger and more permanent they can be more comfortable for the patient because the metals used are light and thin. Acrylic dentures are mostly used as a temporary or transitional but sometimes are recommended for a longer period of time. Partials can be done as a temporary placeholder for missing teeth to prevent your natural teeth from shifting into the open space while waiting for a dental implant.
