Biomechanics also makes use of techniques of electrical recording of mechanical quantities by means of mechanotrons, sensors of angular movements, and support dynamographs. Types of Removable Partial Dentures Tooth-Mucosa borne (extension base) Exhibits one or more edentulous areas which are not bordered by abutment teeth Functional forces are shared by both the abutment teeth and denture bearing surfaces in the extension. Maximum support is gained from the adjacent soft tissue denture bearing surfaces. Now customize the name of a clipboard to store your clips. Extension Based RPD’s This retainer serves two purposes Retention – Frictional In the event the distal molar is lost This retainer can be slightly can be slightly recontoured and bent to engage the undercut of the canine. Our objective is to create the best and most comprehensive online programs of instruction in Prosthodontics. Such retainers should be placed at the height of contour, 42.
