TITANIUM CLAMPS WITH MODIFIED SURFACE AND THEIR APPLICATION FOR MANDIBLE OSTEOSYNTHESIS

Abstract

Objective: To develop titanium clamps with a biologically modified surface, and estimate its biocompatibility and probability of its application in clinical practice for patients with mandibular fractures. Methods: The experimental research was conducted on laboratory animals, as well as in treatment of 14 patients with mandibular fractures, to study biocompatibility of the designed titanium clamps. All the patients underwent osteosynthesis of the lower jaw with the application of the designed titanium clamps with a biologically modified surface. Results: It has been revealed that the all-cast titanium clamps with the laser-processed surface most optimally meet the requirements imposed to the materials applied to mandible metalosteosynthesis. Conclusion: The application of the designed titanium clamps with a biologically modified surface allows accurately fix and hold lower jaw fractures in the exact physiological position until final consolidation.
