Three holes for screws for fixing the plate in the condyle are located at the joint of said arms and said holes are arranged at the top of the vertices of an isosceles triangle, while at the lower ends of the arms there are two holes for screws for fixing the plate in the ramus of the mandible. The plate (1) has a first arm (2) and a second arm (3) bent outwardly in relation to each other, wherein said arms are in the shape of arc, the radius (R2) of the arc of the first arm (2) is greater than the radius (R3) of arc of the second arm (3), the crossbar (4) is a cross-shaped crossbar in the shape of letter X, wherein four arms of said crossbar (4) are directed towards the respective holes (61, 62; 71, 72) for screws for fixing the plate (1) in the ramus of the mandible.
