摘要:
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 dam-age 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.
