Abstract of the Disclosure The insert is held in place by surrounding plastic filling material and improves resistance to abrasion. Bonding to the filling material is improved by impregnation of the insert with a wetting agent or filling material. The insert may be made by extruding a porcelain paste into the desired crossection segments. Porosity of the fired material is obtained by mixing a volatile binder, such as polyethelene glycol, with the ceramic powder. Acid treatment is also disclosed for providing the desired porosity.
