Application of fiber titanium nickelide for residual bone cavities filling

ABSTRACT Aim: to study the osteoplastic properties of fibrous and granular porous titanium nickelide and the opportunities of using this implant in clinical practice.

Materials and methods: fibrous and porous granular titanium nickelide was used to fill bone defects and cavities. The experiments were carried out on Chinchilla rabbits weighing about 2.5–3 kg. As an anesthetic we used Zoletil 100 2 ml. After hydro-preparation with ultracaine DS 1.8 (1: 200 000), a cut along the edge of mandible was performed. Then, the alveolar process of the mandibular body was skeletonized, and the periosteum was exfoliated. After that, with the help of a fissure bur, an artificial defect about 5 mm long was formed. For the purpose of osseointegration and enhancement of osteoinduction, the reproduced defects were filled with granular or fibrous titanium nickelide. Then the wound was covered with a net of fabric titanium nickelide of the appropriate size, which served as a membrane. Wounds over the defect were layer-by-layer sutured with nodal sutures.

Results. Subsequent germination of the implant with a newly formed bone tissue confirmed the osseointegration properties of titanium nickelide. In addition, there were no dystrophic and necrotic changes in the tissues around the defect, which may indicate the low toxicity of the material. Conclusion. The use of fibrous titanium nickelide for filling the residual bone cavities of the maxillofacial area allows the effective restoration of the lost bone structures. Its application seems to be the most convenient and ergonomic.

Key words: granulated titanium nickelide, jaw defects, osteoplastic materials, nitinol.
