Abstract

A method of manufacturing a dental post according to the present invention comprises the steps of: (i) overjacketing extrusion of at least one thermoplastic material over at least one filament or yarn, such that the thermoplastic material cross-sectionally enwraps the at least one filament or yarn; (ii) solidifying the extruded product of step (i); (iii) equipping the solidified extruded product of step (ii) with a surface texture, such that the thermoplastic wrapping is not modified in a way as to expose or damage the at least one filament or yarn.The invention allows for more flexibility in the manufacturing of dental posts, especially in generating surface textures of such dental posts.
