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.
