AP-Geschiebe sind ausschließlich als intracoronale Geschiebe und in Verbindung mit einem Schubverteiler und Interlockbohrung einzubauen!
Without stress distribution arm and interlock the masticatory force will lead to a deformation of the female resulting in a loss of friction. At worst the complete prosthesis must be replaced.

Before duplicating the model flush the lateral areas with wax so that after finishing the metal structure so that a space is left between male and metal structure in order to make sure that the attachment can be activated later!
