INTRAOSTEAL DENTAL IMPLANT Russian patent published in 1998 - IPC

FIELD: surgical stomatology. SUBSTANCE: endoossal section 1 of implant is made as two parallel zigzag springs coupled at ends and manufactured of nickelide-titanium wire with shape memory effect. Springs are oriented in direction of zigzag of zigzag translation orthogonally to axis of supraossal section 2 which is made as two vacant ends of zigzag springs 3 twisted into helical bundle. Planes of springs deviate from axis direction of supraossal section 2 through angle of 5-10 deg. When implant is installed in osteal bed prepared for it beforehand it is preliminarily deformed in cooled down state to plane-parallel form of endossal section 1. When device is heated springs try to return to initial form of their angular position relative to each other and become self-secured in osteal bed. EFFECT: more effective implantation. 2 cl, 4 dwg
