These prostheses are subdivided into two types, full dentures and partial dentures.
Complete Dentures, more commonly known just as dentures. This are recomended when the patient has no teeth, and is thus lacking tissue-pillars for support. The support of the prosthesis is taken from a wide base that extend over the surface of the mucosa in the alveolar process. They can be unimaxillar or bimaxillary, ie top, bottom, or both, if the patient has no teeth in either arch. With this type of prosthesis, it is necessary to achieve an occlusal balance of the upper and lower joint, taking into account the jaw movements, chewing, the stability of the prosthesis, etc.
