Details and patient eligibility


The goal of this clinical trial is to test the effect of nerd neck correction on damaged jaw in people who suffers from jaw problems and nerd neck. The main question it aims to answer: * whether there are different effects of traditional nerd neck correction exercises, device correction method and dental splints on jaw features of pain and function. Participants will: * participants will be given the consent to sign first. * participants will be assessed to check jaw pain and function. * participants will be divided randomly into 3 groups. * Each group will be given the treatment sessions for 6 weeks. * participants will come back after 6 weeks for one last assessment. Researchers will compare traditional, new and dental treatment groups to see if there is improvement in jaw characteristics.

Full description

The relationship between the two conditions of forward head posture (FHP) and temporomandibular joint dysfunction (TMD) have been previously stated with comparing the craniocervical angle (CVA) of TMD patients to the healthy individuals, still a clear relationship couldn't be drawn due to different study limitations such as the lack of subdivision in the TMD patients based on their diagnostic subcategories in addition to, patients posture might have been altered while the photo was captured. Ever since, multiple researchers deliberately investigated the two conditions association and inferred the following: 1. FHP can be a risk factor resulting in TMD where any alteration in the head position produces more tension on the masticatory muscles by changing the mandible position 2. TMD origins from muscular component is more significant than articular component yet the correlation between head posture and TMD is still not clear enough, however, if FHP and myogenic TMD were linked preventive measures can be taken. recently, multiple studies established a relation between the occurrence of FHP in TMD patients which supported the hypothesized relation between them. Till present, no study has investigated the FHP Denneroll cervical traction orthodontic (DCTO) correction impact alone on TMD and this is where the purpose of this study arises from.


63 estimated patients




18 to 50 years old

consists of one strengthening exercise for 10 repetitions in 3 sets each, and two stretching exercises with a hold for 20-30 seconds.
Other: stretching and strengthening exercises
Dental management
Active Comparator group
formed soft occlusal splint will be individually designed for the upper arch of each participant.
Device: Vacuum-formed soft occlusal splint
