[Use of biomaterials for preventive and restorative purposes]

At the Dept. of Maxillofacial Surgery, Semmelweis University of Medicine many biomaterials have been used in the last 10 year. Author deals with only three materials, such as solid aluminiumoxyde ceramics, titanium screws and HTR Polymers. The Al2O3 ceramics can be used for the reconstruction of the lower jaws, the condyle and the coronoid process of the mandible as well as for dental implants and for the improvement of the facial contour. This material proved to be the most suitable for the reconstruction of the mandible and TM joint. The titanium screw implant (Flexi-root system) has been used in many hundreds of patients with some 90% success rate. The HTR Polymer has been used in the periodontal surgery, in small and medium size cyst operations and sinus lift procedures. The technique of sinus lift has also been discussed.
