In the present embodiment the lateral guide surface 49 is not part of the associated bearing part 53 but a separate component likewise mounted on the associated articular housing 39 which, in the present embodiment, is formed by a cylinder 54 which is mounted so that it is offset so far to the rear and below and parallel with the swivel axis 5, which in the 0-position is the centre axis of the articular heads 36, so that its outer surface 55 forms the lateral guide surface 49. The arrangement of the cylinder 54 is such that in the 0-position its outer surface 55 together with the rear end region of the sagittal guide surface 46 bounds rearwardly the articular pins 36 formed by a respective spherical head 36a. In this rear bearing position, which corresponds to the final biting position, the contact point B between the spherical head 36a and the sagittal guide surface 46 lies in a vertical transverse plane E2 containing the swivel axis 5, while the contact point C between the spherical head 36a and the lateral guide part 54 lies in a plane E3 containing the swivel axis 5 that may be arranged approximately horizontally, preferably inclined to the rear at an angle of about 30 articular recess 40 may be open or can have a space or slit 56 which can extend from the contact point B in the shape of a crescent moon and which enables retroversive movement of the upper part 37a of, e.g., up to about 1.5 mm when the lateral guide part 54 is dismounted, which will be described below.
The first degree of freedom includes a pivot bearing 83 (FIG. 11) in which the associated articular housing 39 can be rotated about the swivel axis 5 and fixed in the relevant rotational position. Consequently the inclination of the sagittal guiding path 46 (which is also known in the art as a condyle path) can be adjusted as desired in an angle range between about -15 facilitate the adjustment a scale is mounted in the region of each joint between the associated articular housing 39 and the hub part 38 of the upper part 37a on the edge of the hub part 38 or of the articular housing 39. Preferably there are two scales, of which the one indicates the rotational position relative to the Kamper's plane and the other to the Frankfurt horizontals. The two pivot bearings 83 are arranged as mirror images with reference to the vertical longitudinal centre plane E1.
The second degree of freedom is formed by a pivot bearing 94 (FIG. 6) in which each bearing part 53 can be rotated about a vertical axis of rotation 94a and can be fixed in the relevant rotational position. By this means a selected Bennett angle 48 from, e.g. about 5 can be set. The vertical axes of rotation 94a intersect the swivel axis 5, i.e. the bearing parts 53 can be adjusted horizontally about the 0-point of the swivel/sliding bearing 11. In the present embodiment each bearing part 53 has a vertical, upwardly projecting bearing bolt 95 which passes upwards through and projects from a hole 96a through the wall 96 of the associated articular housing 39 located thereabove. With an adjusting nut 98 that can be screwed on to an end thread on the bearing bolt 95 and which e.g. by means of a sleeve 97 is effective against the preferably flattened upper side of the articular housing 39, the bearing part 53 can be tightened in its respective rotational position and released again. To facilitate manual rotation, gripping grooves 99 or gripping ribs are provided on the front side of the bearing part 53. By means of a scale in the region of the joint between the articular housing 39 and a part, e.g. the sleeve 97 that can rotate with the bearing part 53, the desired rotational setting of one or both bearing parts 53 can be adjusted accurately.
With the lateral guide part 54a, shown in FIGS. 14 to 16, the lateral guide surfaces 49a to 49e are arranged on the head part 116 of a bolt shaft 117. In the present exemplary embodiment five shift angles 52 are realised that are gradated relative to one another and which extend over a range of about -10 surface 49e, up to about +30 the lateral guide surface 49c. The lateral guide surface 49a is formed axis-parallel in the Y direction so that its shift angle is equal to zero. The lateral guide surface 49e with the shift angle 52 lying in the negative region can be realised by a segmental radial projection 116a in the lateral outer end region of the head part 116.
