Patients with temporomandibular dysfunction (TMD) are often affected by muscular symptoms. In recent years, scientific opinion has frequently recommended collaboration with physiotherapists for TMD patients. The RelaxBogen was the result of such interdisciplinary collaboration between dentists and physiotherapists. It imitates a specific form of relaxation technique - based on the myofascial release technique - for the masseter and temporal muscles. This article describes two cases from a pilot study. The case studies were presented by the author as a lecture entitled "The RelaxBogen, a new method of treatment for bruxism and TMD - a pilot study" at the 2016 Annual Conference of the DGFDT. They demonstrate the possibilities offered by the RelaxBogen for treating myogenic TMD and headaches. After 3 months of wearing the device, patients reported considerably reduced headaches and pain on palpation. Apart from a reduction in the general pain level, pain reduction was also documented in the head/jaw, cervical spine, and neck areas. Keywords: TMD, bruxism, myalgia, headaches, myofascial pain
