An occlusal splint arrangement (01) for sleep apnoea therapy includes a maxillary miniplast splint (02) that can be arranged on the maxillary row of teeth and a mandibular miniplast splint (12) that can be arranged on the mandibular row of teeth. The miniplast splints (02, 12) each have positioning device (05, 22) that can define the relative position of the miniplast splints (02, 12) towards each other in the longitudinal direction (X). For simple adjustment of the position, exchangeable positioning devices (22) that are mounted on centring pins (15) are used on one of the two miniplast splints (02, 12). A secure attachment of the respective exchangeable positioning devices (22) on the centring pin (15) is realised by a latching connection.
