case_images: The first visit was in fact a virtual one, the patient, providing preliminary photos and some X-rays (Figure 1A,1B,1C,1D,1E; Figure 2), considering that her chief complaint was severe headache resistant to all common painkillers.

case_images: The full cone-beam computed tomography (CBCT) taken to establish the possible teeth to be saved through endodontic treatment was useful also for the primary evaluation of the bone loss (Figure 3A,3B,3C,3D,3E).

case_images: Huge VD loss and failed prosthetic treatment both on upper and lower arches, the severely grinded upper incisors, lower anterior teeth consumed and tilted inwards (the ceramic was absent on the zirconia restorations) and worn partial denture could be observed (Figure 5A,5B,5C,5D,5E).

case_images: Myotronics K7 Evaluation System analysis was proposed to the patient for establishing a correct starting point for the future full mouth rehabilitation. Moreover, the upper central crowns were removed, and a layer of light cure base plate was applied over the lower denture (Figure 8, A and B). Noting the deep bite, the lower denture was transformed by adding a layer of light cure denture base material (Figure 8C), which was intended to have a reduced quantity of bite registration silicone while transferring the myocentric position and starting the CMS and sEMG registration (Myotronics, Inc., Kent, WA, USA) (Figure 9).
