Completely polymerized occlusal splint in therapeutic position
To be able to add the acrylic without problems, the models, fixed in a semiadjustable articulator are blocked out with wax. For this purpose, a thin wax strip is laid around the tooth arch and fixed approximately 0.5 mm over the gingival margin. Spaces of missing teeth and retentive areas are also blocked out.
The acrylic is not added with the spray-on technique but favorably with the dough technique. After a couple of minutes, when the dough does not flow any more, it is pressed onto the cast. The incisal edges and the occlusal surfaces have to be totally covered with acrylic. It is polymerized in a pressure vessel.
When working out, all impressions of the counter jaw in the posterior and front region are reduced in such a way that only slight impressions remain. Distally of the canines, an acrylic guiding surface is added for the fixation of the occlusion. This stop should be adjusted in the semiadjustable articulator with articulating tape.
