Objective: Improving the technology of creating and manufacturing individual implantation designs in maxillofacial surgery based on stereolithographic stimulation.
Methods: The study is based on the analysis of the results of treatment of 12 patients aged 17-40 years with different pathologies of the mandibular bone structures: adamantinoma – 5 (41.7%), posttraumatic deformities – 2 (16.6%) and bisphosphonate-related and radiation-related necrosis of the lower jaw – 5 (41,7%). Both clinical and laboratory methods of examination of all patients were carried out according to the traditional scheme, and as a radiologic study, we chose CT in the 3D printer mode. Its indices allowed creating an additive technology of reproduction and manufacturing of a stereolithographic model of the maxillofacial bones. On these models, taking into account the volume, size of the defect and its individual characteristics, a wax composite was prepared, and then prepared a design of an endoprosthesis made of nickel-titanium alloy.
Results: The results of surgical interventions in 12 patients who underwent substitution of mandible defects were performed using implant structures based on CT data in a 3D printer mode using stereolithographic models, showed their high efficiency. All the operated patients had a primary wound healing in the postoperative period, earlier restoration of the volume of the lower jaw movement, which is confirmed by clinical and electromyographic studies of the function of the masticatory muscles of the operated zone.
Conclusions: The use of individual implant structures to replace bone defects of the lower jaw, created in the 3D printer mode on stereolithographic models, allows to shorten the operation time and fully restore the lost anatomical and aesthetic disorders of the maxillofacial area.
