METHOD FOR MANDIBULAR BONE GRAFTING Russian patent published in 2014 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: implant consisting of a reconstructive mandibular plate embraced through a thickness of the mandibular bone tissue with a nonwoven titanium material of through porosity within the boundaries, at 1-4 cm from an edge of the reconstructive plate; the material is implanted into a spongy portion of the ilium by applying the implant on the pre-decorticated iliac crest at the length of the reconstructive plate followed by a growth procedure for 3-8 weeks. After the bone tissue saturation of the implant, the prepared implant is removed from the ilium and placed within the mandibular bone defect with a pre-created receiving bed. A surgical area is processed. Under general anaesthesia, the lower jaw is resected, and fragments are reduced. After removal from the ilium, the prepared implant with the saturated bone tissue is intraoperatively secondarily embraced with the nonwoven titanium material with through porosity to fill a deficient volume of the soft tissue within the lower jaw thereby forming a damper pad. The damper pad is uniformly coated with a suspension of autologous multipotent mesenchymal stromal cells with bone chips prepared by removing the implant from the ilium. The [late ends are fixed to the lower jaw with fixing screws. The wound is closed in layers. An orthopaedic treatment is performed 2-4 months after the operation.

EFFECT: by the high regenerative potential of the autologous multipotent mesenchymal stromal cells and reinforcing the bone tissue with the nonwoven titanium material with through porosity, the method enables filling the defect of a complex of soft tissues within the lower jaw, reducing the injuries of the method, reducing the resorption processes of the implant and the lower jaw.
