[A procedure for improving the stability of the total mandibular prosthesis with the aid of the muscular factor in the marked atrophies of the mandibular crest].

The study aimed to define factors involved in improving the stability of total mandibular prostheses by the use in optimal conditions of the muscular factor. This is achieved with a special method for casting of the neutral space which allows to prepare the external surface and to place the artificial dental arc according to objective functional criteria. In the first part of the study notions are discussed related to the practical solution of the problem, such as: the anatomo-functional study of formations which define the neutral space, aspects of the neutral space in the total edentate, and the conformation of total prostheses, as well as the placing of the artificial dental arcs in relation to the neutral space.
