Objective: to evaluate clinical cases with the usage of individual endoprostheses made of biocompatible composite materials based on hydroxyapatite and methyl methacrylate using computer modeling and subsequent manufacturing for reconstruction of the facial skeleton.
Material and methods. To create a 3-dimensional model of a bone defect, computed tomography (CT) is used. The obtained DICOM data is converted into stereolithography files using an algorithm for creating individual implants. After that the model is printed on a stereolithographic printer. Hydroxylapatite – HAP-99g was used to make the implant; the resulting model is released from the molds and sterilized.
Results and discussion. In the cases enrolled in this research work, the post-traumatic defects of the upper jaw, lower orbital margin on the left and upper jaw on the left were corrected. Conclusion. The use of HAP-based composite materials to replace bone defects in the skull allows to significantly improve the effectiveness of treatment and the quality of rehabilitation of this complex category of patients. Key words: bone defects, Hydroxylapatite — HAP-99
