Arrangement of occlusal splints (01), especially for sleep apnea therapy, with a maxillary miniplast splint (02) that can be arranged over the maxillary arch, and a mandibular miniplast splint (12) that can be arranged over the mandibular arch, in which the maxillary miniplast splint (02) can rest against the mandibular miniplast splint (12) and in which the miniplast splints (02, 12) are made with flat support surfaces (04, 14) arranged facing each other fundamentally in the occlusion plane (09), which comprises at least one maxillary positioning means (05) and at least one mandibular positioning means (22), which can be defined by dragging between the maxillary and mandibular positioning means (05, 22) the relative position of the miniplast splints (02, 12) relative to each other in the longitudinal direction (X) and / or in the transverse direction (Y), and where on the left side and on the right side in the area mol ar is arranged in each case a positioning means (05r, 051, 22r, 221) for each miniplast splint (02, 12), and in which the maxillary and / or mandibular miniplast splints (02, 12) have at least one mounting means (15), at least two different positioning means (22a, 22b, 22c) being able to be fixed by mutually replacing each other in the same mounting means (15), so that at least two different relative positions can be defined between the miniplast splints (02, 12), and in which the mounting means is a centering pin (15), wherein the interchangeable positioning means (22) has a centering housing (25) complementary to the centering pin (15) for the mounting on the miniplast splint (12), and in which the interchangeable positioning means (22) can be fixed by placing the centering housing (25) on the centering pin (15), and in which the pin centering (15) allows at the same time a centering of the means of p ossification (22) and a fixation of the positioning means (22), and where the interchangeable positioning means (22) is made in the form of a fin, th
