Main Advantages (Strengths) of the Device
The disadvantages of the known methods of manufacturing metal implants are to obtain an insufficiently developed surface and the impossibility of significantly increasing the strength of the finished metal implant. Therefore, we propose to create a grid of cylindrical depressions on the surface of the intraosseous part of the cast implant by intensive deformation local clover with an ultrasonic concentrator of an appropriate size. As a result of such treatment of the surface of a smooth cast metal implant, a developed surface and roughness with increased mechanical strength are created due to the formation of a nanostructured state in the surface layers with finishing intense plastic deformation, which provides an increase in the specific surface area of the titanium implant, its adhesion force with the patient's bone tissue (biocompatibility), resistance to fracture and, thus, increased service life of the implant.
Main Characteristics
- The service life of the medical device doubles;
- Biocompatibility is improved.
- The specific surface area of the titanium implant is doubled compared to the untreated surface;
- The strength of the surface layer and the bending strength of the entire implant increases 3 times;
- Fatigue strength of titanium ball implant is increased due to formation of compressive stresses in surface layer;
- Increased adhesion of the implant to the bone tissue of the patient.
Marketing Readiness
Methods of making metal implants are known, including various treatments to increase their surface area and roughness:
- producing grooves on the surface of the metal implant by laser ablation;
- creating a relief surface of the titanium implant by ultrasonic cavitation in sodium chloride solution;
- forming surface depressions by chemical etching through masks;
- creation of relief surface of titanium implant by means of roller corrugation (minting).
The disclosed method of producing a titanium implant with a developed surface is characterized in that the creation of a mesh of cylindrical depressions on the surface of the intraosseous part of the cast implant is carried out by intensive deformation local clover with an ultrasonic concentrator of a suitable size.
