For the targeted growth of osteoblasts on the human or animal jaw bone, it is known to form cavities in a molded part. Osteoblasts can grow in these cavities and thereby fill bone defects or augment the height and/or width of the jaw. However, in the event of relatively large lesions, some of these materials do not offer sufficient stability for satisfactory osteogenesis or ossification and moreover are absorbed too quickly and unevenly. As a result, the objective of filing or augmentation is often not met. The invention provides a biocompatible molded part for supporting new bone formation, in particular the reformation of a jaw bone or a jaw bone portion in a mammal, preferably a human, wherein the molded part is suitable to be placed on the jaw bone and is designed as a solid body. The invention also provides a composition for producing a biocompatible molded part, a method for producing a biocompatible molded part, a use of a biocompatible molded part and a kit comprising a plurality of molded parts.
