Dentures are structures to replace missing dental pieces and the patient can remove them. When they are partial they can have metal with acrylic parts which have attached missing pieces, this option has a lot of advantages when the missing pieces cannot be replaced with dental bridges or implants. Complete prosthesis is done when the patient has lost all his/her pieces.
The partial prosthesis is kept in the mouth through pins that are house in some of the pieces when they are placed in the mouth. Also, it is supported over the gums in those parts where there are no pieces. In case of complete prosthesis implants can be used to provide better retention. They improve facial appearance problems, smile design, also it provides bite stability, due to the high quantity of pieces and bond lost.
