Abstract

Taking a physiological occlusal registration with the neuromuscular concept is of great help in achieving a functional and esthetic restoration.

When the number of teeth involved in chewing decreases due to tooth decay, or when more teeth become loose due to periodontal disease, people tend to eat only soft foods. Such eating habits lead to disuse atrophy of the chewing muscles.

Loss of muscle tone and bone mass in the jaw reduces the size of the lower face gives the face a flabby or drooping appearance, lips look shrunken. In some people, sagging jowls may create the look of a double chin.

Patients who do not have a well-established intercuspal position rarely complain of temporomandibular joint disorder symptoms such as pain in the masticatory muscles or joint noises.

In cases of edentulous patients who undergo All-on-4 implants and can chew on the day of surgery, the previous habitual bite position is often in a posterior position. When the lower jaw is shifted backwards, the sagging under the chin, nasolabial folds, and marionette lines become more noticeable. It is more aesthetically pleasing to obtain a bite registration using the neuromuscular concept than to restore function in the current position.

I will present some cases in which we have treated patients with All-on-4 implants and Neuromuscular bite, achieved both aesthetic and functional recovery.
