training with RehaBite industry report Fig. 1 Fig. 2 Fig. 3 Fig. 4 for the patient to accurately and faithfully repro- duce training conditions (Figs. 2 & 3). Biofeedback in combination with active training can intensify motor learning processes.12 Spontaneous modi- fications of the intra- and intermuscular patterns of contractions of the muscles involved and phys- iological activation are frequent efects. In the case of painful muscular jaw opening restrictions, the training is supplemented by in- tensive stretching exercises (Fig. 4). By using the post-isometric relaxation that is the result of the coordinative bite, the stretching efect is increased further still. The training exercises can either be performed under the instruction of the treating doctor or physician, or the patient may also use the RehaBite device for individual training, regardless of time or place, and can be further supplemented by exercises like gentle muscle massages. Coordinative training for relieving TMD symp- toms is very efective, and in some cases, neces- sary for patients undergoing orthodontic treat- ment. Home exercises like gentle massage and training tools such as RehaBite have shown sig- nificant results by improving muscle coordina- tion and resolving relieving postures. about Dr Daniel Hellmann is senior physician of the Department of Prosthodontics, University Hospital Würzburg, Germany.

Fig. 2 How the RehaBite works. Biting on the elastic bite fork applies an impact of force to the liquid in the closed hydrostatic system. This force is transmitted to a mobile piston connected to a mechanical spring. The piston moves up and down in front of the handle. The tip of the piston can be felt with the fingertip at the front of the handle. The RehaBite allows five levels of intensity, which can be adjusted with the integrated force control screw at the front of the handle. Fig. 3 Bite training with finger feedback.
