摘要：
The technical solution relates to medicine, namely to surgical and orthopedic stomatology and may be used for installation of dentures.The technical result of the claimed technical solution is increasing durability and the establishment of a permanent, not changing during use, the efforts of fixation of the denture and reduce the impact of the latter on the gums, leading to a longer service life and ease of operation.The technical result is achieved in that the device for fixing a dental prosthesis, comprising vnutrikornevuyu and coronal portion detachably interconnected, thus vnutrikornevaya portion is formed as a threaded rod for mounting in an implant, rolling in supragingival part - abutment crown part consists of crowns and metal inserts placed inside a metal insert, a shock absorber support member made annular grooves around the perimeter on the inner surface thereof and comprising means phi sation it in the form of a clamping ring, wherein the abutment comprises an upper truncated cone with a spherical surface on the top and bottom of an inverted truncated cone, the support member is a seat with a spherical surface interacting with the spherical surface of the abutment, wherein the crown portion further comprises a retaining ring inserted into the corresponding bore for mounting the seat and the shock absorber disposed between the seat and the inner end surface of the insert, the clamping ring fixation means uu spring formed with an internal tapered bore and installed with a certain gap in the corresponding bore and a shoulder fixed metal insert, wherein the slope angle of the conical surface larger than the friction coefficient between the abutment pictures and pictures of the clamping ring, that is:tgα> k, where α - angle between the conical surface of the abutment and its axisk - the coefficient of friction.Furthermore the support element in the form of a saddle, made of wear-resistant high-alloy steel.Furthermore shock absorber made of rubber.Moreover cla
