[Dentin ossicle prostheses (DOP)--a new concept in replacing the ear ossicles].

The variety of materials used for replacement of the ossicles is proof enough that no single material can satisfy all criteria: availability, mouldability, stability and biocompatibility. The trouble-free availability as well as the excellent mouldability enable the development of a principle of preparation of ossicular replacement prosthesis from homologous dentine. The moulding of the dentine ossicular prosthesis is simple and can be performed with an equipment available at any otologic department.
