In order to overcome the need for secondary intervention to remove metallic osteosynthesis devices after fracture healing, endeavours have been directed towards developing resorbable osteosynthesis materials during the last decade. The resorbable material must fulfil a number of basic demands. For example, an adequate holding strength of these materials is essential for undisturbed fracture union, complete resorption after bone healing, good histocompatibility without any damage to the surrounding tissues and without detrimental distant effects within the organism. Suggested materials are primarily high-polymerlactic acid or glycolic acid compounds. In particular, research was concentrated on the enhancement of the mechanical properties and biodegradation of polylactides. Debris high in crystallin was found to be responsible for late soft tissue reactions. To achieve disintegration products with lower crystallin content stereocopolymeres of lactic acids are preferred nowadays. Based on our experimental work, another osteosynthesis system manufactured from autoclaved allogenic bone tissue was developed as an alternative. This has osteoconductive properties and converts by creeping substitution into bone. In contrast to metallic plates and screws, the modulus of elasticity is quite similar to vital bone tissue. The initial strength enables its use in the field of maxillofacial surgery.
