About
The study aims to compere mandibular splint versus botox injection in lateral pterygoid on cervical muscle activity in patients with temporomandibular disorders
Full description
Temporomandibular disorders (TMD) are common chronic musculoskeletal pain conditions among orofacial pain, consisting of a group of conditions associated with pain and dysfunction of the temporomandibular joint (TMJ) and masticatory muscles. Temporomandibular joint displacement, also known as internal disc derangement, is an abnormal relationship between the articular disc, the mandibular condyle, and the mandibular fossa. The most frequent displacement of the disc is anterior to the mandibular condyle however, in rare cases it can be posteriorly.
Occlusal splint treatment is generally considered to be a basic treatment for Temporomandibular disorders. It could promote correction of the vertical dimension, maxillo-mandibular realignment, temporomandibular joint repositioning and cognitive awareness. Although various splints are currently available, the most used are stabilization splints and anterior repositioning splints.
Injection of BTX-A in LP muscle, considering the different methods, frequencies and injection dosages used in different studies, would decrease the clicks and other TMJ-related disorders such as pain, hyperactivity, and dysfunction. Based on the present review, most studies about the injection of botulinum toxin in LP muscle reported cases or were done as quasi-experimental studies.
