An intraosseous screw implant pertains to medical equipment. The device is made with a variable height of the single-thread profile (2). Within the full turns (8) of the screw line, projections (7) with an increased height of the thread profile (2) are localized. The projections (7) are intended to bear the immediate load of the orthopedic structure. The projections (7) are located on adjacent turns (8) and are mutually offset by an angle. In an alternative embodiment of the device, the projections (7) are located from each other through a turn (8). The method for installing the implant includes forming a bone bed in the form of a narrowing opening. The dimensions of the opening are selected based on the condition of free accommodation of the predominant part of the implant. The implant is inserted into the cavity of the bed with the projections (7) resting on the spongy bone layer. Then the implant is screwed into the bone with several turns for fixation. The shape of the implant is optimized based on the condition of intensification of osseointegration of the immediately loaded implant. Reduced traumatic effect of implant screw elements on bone while ensuring immediate biomechanical load. Compacted bone tissue particles in the chip groove (4) at the top of the implant. Increased reliability of osseointegration. Increased implant survival level.
An intraosseous screw implant made with a variable thread profile height (2), characterized in that it contains such turns (8) of the helical line that within each of them at least one projection (7) with an increased thread profile height (2) is localized, having a shorter length compared to the length of the turn (8) of the thread (2), wherein said projections (7) are located on adjacent turns (8) and are mutually offset by an angle or are located from each other through a turn (8).
A method for installing an intraosseous screw implant, the overall shape of the body (1) of which in the middle and neck parts is characterized by a narrowing towards the top, containing such turns (8) of the helical line that within each of them at least one protrusion (7) with an increased height of the thread profile (2) is localized, including the formation of a bone bed in the form of a tapering opening, the dimensions of which are selected from the condition of free accommodation of the predominant part of the implant with an emphasis on the spongy layer of the bone of the protrusions with an increased height of the thread profile (2), after which the implant is inserted into the cavity of the bed until it stops, and then screwed into the bone for fixation.
