摘要：
A retention system to fix a complete denture in a mandible, comprising: implants ( 8 ), connectors ( 9 ) with screws, a bar ( 3 ) having a form of two sleeves (3A) interconnected by means of a span ( 3B ), a bar casing ( 1 ) with a cavity having a negative shape of the bar cross-section perpendicular to an axis of its holes, and a set of drill guides, which hole diameters increase gradually. The retention system comprising additionally a template of the bar casing ( 1 ), which shape and size correspond to the bar casing ( 1 ), wherein the drill guides, used for precise drilling parallel holes for an implant placement, consist of two drill guide sleeves, interconnected with a drill guide span, and the outer diameter of the drill guide sleeves corresponds to a diameter of holes ( 1A ) in the bar casing ( 1 ) and of holes in the bar casing template, whereas a distance between axes of the drill guide sleeves is exactly equal to a distance between axes of holes in the sleeves ( 3A ) of the bar ( 3 ). An axis ( 13 ) of a hole ( 11 ) of the connector ( 9 ) is eccentrically offset with respect to an axis of an outer surface ( 12 ) of the connector ( 9 ), enabling, by rotation of the connector ( 9 ), a precise setting of the bar ( 3 ) in relation to the implant ( 8 ), and thus elimination of stress formation.
