There's no gain without pain, but some pain have not a single gain! We are all familiar with the nasty tension and soreness of head and neck muscles, or the noisy grinding pain of the two joints driving all our oral functions. Such hereditary or acquired disorders slow down our abilities and ambitions in life. Adding insult to injury, they are reluctant to vanish with a simple procedure, if not feeding on our daily stress that complicates the symptoms with bruxism. Strong relations are drawn between these Temporomandibular disorders (TMDs) and the dental occlusion conditions, which led to the ubiquitous use of debatable occlusal therapies (oral splints and occlusal adjustments) to alleviate the symptoms. This book is a well-thought-out teamwork of a highly-credited Evidence Based Dentistry crew, processing the randomized controlled trials (RCTs) running over the last 40 years of treating joint or muscle TMDs with the standard occlusal therapies all over the world. Respecting the most recent protocols of conducting systematic reviews and meta analyses, we offer patients, clinicians and researchers with the highest evidence for the effect of occlusal therapies to relieve pain.There's no gain without pain, but some pain have not a single gain!
