Anatomical features of the upper jaw related to removable prosthetics

The maxillary bone is placed centrally, within the facial cranium, it is involved in the aesthetic appearance as well as it being related to normal vital functions ¿ eating, breathing and speaking. There are physiological changes in the jaws of the growing organism, which are influenced by the presence or absence of the teeth, parafunctions, and transference of the masticatory pressure. Anatomical features of the upper jaw are directly related to the prosthetic method of choice. The development of modern technologies can facilitate many of the stages of prosthetic treatment, but cannot replace anatomical conditioning. In the cases of complete edentulism, there are only two treatment options ¿ complete dentures fabrication and a fixed or movable prosthesis after the implant placement. The bone implantation shapes and provides a sufficient volume for a successful outcome of treatment that can be applied in the case of fixed prosthesis.
