The goal of this clinical trial is to test the additional correction effect of nerd neck on damaged jaw in people who suffers from jaw problems and nerd neck at the same time. The main question it aims to answer:
• whether the additional correction of nerd neck impact the jaw features of pain and function.
Participants will:
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 suspected relation between them but without a clear association. Till present, no study has investigated the additional effect of FHP DCTO correction impact on myogenic TMD, and this is where the purpose of this study arises from.

Permuted block randomization to ensure an equal number of allocations in each of the three groups (Conservative only and conservative with Denneroll cervical traction orthodontic). Each random block was stored in opaque sealed envelopes consecutively numbered with a third researcher. Once each participant officially joins the study the researcher will open the subsequent envelop.
