SINGLE STAGE ALL-PURPOSE DENTAL IMPLANT Russian patent published in 2006 - IPC A61C8/00 

FIELD: medical engineering.

SUBSTANCE: device has intraoral, sub- and intraosseous parts made as a whole with each other. The intraosseous part has hemispheric apex portion. The implant is manufactured from partially stabilized zirconium dioxide crystal of nanostructure having <100> axis coinciding with the implant axis. Intraosseous part surface is wave-shaped and its vertical plane profile in the direction from subosseous part towards the apical end is convex circular arcs relative to the implant axis with reducing radii of R_11> R_12> R_13> R_14>, tangent to the circles makes an angle of ∞₁ = 8-10°. Transition from one convex arc to another is smoothed with a circular arc arranged concave relative to the implant axis, arc radius being equal to R₂₁≈1.1R₁₁, R₂₂≈1.1R₁₂, R₂₃≈1.1R₁₃, R₂₄≈1.1R₁₄. The vertical plane profile of the subosseous implant part is an arc arranged concave relative to the implant axis having radius of R₃≈1.5-1.6R₁₁, ¼ of subosseous implant part belonging to the intraoral part is manufactured as truncated cone turned towards the implant axis to which the cone generatrix makes an angle of ∞₂ = 18-20°.

EFFECT: high strength; high fixation stability; improved serviceability.
