Temporomandibular Joint Disorders

To compare the efficacy of retro discal injection of calcium gluconate-activated PRP versus non-activated PRP in adults with Anterior Disc Displacement with Reduction (ADDWR). Efficacy will be measured by the reduction of symptoms and the restoration of function, specifically targeting the normal Maximum Mouth Opening (MMO) range

The aim of this cross-sectional study is to compare temporomandibular joint (TMJ) and cervical spine parameters between young university students aged 18-30 years with and without text neck syndrome, a modern overuse condition caused by prolonged digital device use and repetitive forward head flexion. Given the anatomical, biomechanical, and functional connections between the stomatognathic system and the cervical region, prolonged altered posture may contribute to TMJ dysfunction, pain, and altered physical metrics. Participants are categorized into two groups based on photographic and self-reported text neck severity (levels 3-4 for text neck vs. levels 1-2 for non-text neck) and evaluated across multiple physical parameters, including craniovertebral and cervicothoracic angles, active cervical and mandibular range of motion, cervical joint position sense, neck and TMJ pain intensity via Visual Analog Scale, TMJ dysfunction severity using the Turkish-validated Fonseca Questionnaire, static balance via the single-leg stance test, and dynamic balance via the Y Balance Test.

Prospective data will be collected in approximately 200 patients treated with an TMJ replacement. Patients will be followed up according to the standard (routine) for up to 5 years after the treatment. Data collection will include underlying disease, treatment details, functional and patient reported outcomes (PRO)s and anticipated or procedure-related adverse events (i.e. complications). This registry is designed to be able to assess the number of patients who refuse alloplastic total TMJ replacement. Therefore, the participating sites are asked to register all cases of refused TMJ replacements too.

Temporomandibular disorders (TMD) are common musculoskeletal conditions affecting the jaw joint and surrounding chewing muscles. Myogenic TMD specifically involves muscle pain and dysfunction, which is frequently accompanied by chronic neck pain due to the close anatomical and neurophysiological connections between the jaw and the cervical spine. The purpose of this study is to compare the clinical effectiveness of two widely used physiotherapy interventions-a clinician-administered manual therapy protocol and a patient-conducted home exercise program-in individuals diagnosed with myogenic TMD and chronic neck pain. The main research question is to determine whether targeted manual therapy applied to both the temporomandibular and cervical regions yields superior improvements in pain, jaw and neck mobility, quality of life, and masseter muscle properties compared to the Rocabado 6x6 home exercise program alone. 1. A total of 34 participants aged 18-45 years with myogenic TMD and chronic neck pain will be randomly allocated into two equal groups: Manual Therapy Group: Participants receive 6 individual treatment sessions (3 days per week for 2 weeks) consisting of soft tissue mobilization, trigger point therapy, myofascial release, and joint mobilization techniques applied to the jaw and neck regions. 2. Exercise Group: Participants perform the standardized Rocabado 6x6 home exercise program 3 days per week for 2 weeks, with adherence monitored through daily exercise diaries. All participants undergo comprehensive assessments at baseline and immediately following the 2-week intervention. Evaluated parameters include jaw and neck pain intensity (Visual Analog Scale), cervical and mandibular range of motion, cervical joint position sense, jaw proprioception, facial asymmetry, bruxism, TMD severity, movement-related fear (kinesiophobia), and quality of life. In addition, masseter muscle thickness and elasticity are objectively assessed using ultrasound imaging and elastography. The findings of this trial aim to provide healthcare professionals with high-level evidence regarding effective, targeted physiotherapy strategies for managing myogenic TMD co-occurring with cervical pain.

The goal of this clinical trial is to learn if arthrocentesis works as well as botulinum toxin (Botox) injection to treat pain and jaw dysfunction in adults with temporomandibular joint (TMJ) disorders. The main questions it aims to answer are: * Does arthrocentesis reduce pain more, less, or the same as Botox injection? * Does arthrocentesis improve jaw opening and function more, less, or the same as Botox injection? * What side effects do participants have with each treatment? Researchers will compare arthrocentesis to Botox injection to see which treatment works better for reducing pain and improving jaw movement in patients with TMJ disorders. Participants will: * Be randomly assigned to receive either arthrocentesis (a joint-washing procedure) or a Botox injection into the jaw muscles * Visit the clinic at 1, 3, and 6 months after treatment for checkups and assessments - Rate their pain and have their jaw movement measured at each visit * Complete short questionnaires about their jaw function and quality of life

The Real Time MRI Rapid Flash sequence is particularly interesting for the study of moving organs and joints. This sequence will make it possible to characterize normal and pathological temporomandibular joint movements by MRI.

The goal of this observational study is to evaluate postoperative outcomes following temporomandibular joint (TMJ) surgery and to compare the effectiveness of intraoperative platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) injections in patients with temporomandibular joint disorders. The study includes adult patients who underwent TMJ surgery and received either PRP or PRF intraoperatively. The main questions this study aims to answer are: Whether intraoperative PRP or PRF injection is associated with differences in postoperative pain intensity and recovery. Whether PRP and PRF differ in their effects on postoperative jaw function, including maximum mouth opening and joint symptoms. If there is a comparison group: Researchers will compare patients who received intraoperative PRP with those who received intraoperative PRF to assess differences in postoperative pain, functional outcomes, and joint-related symptoms. Participants will: Have their existing medical records reviewed retrospectively. Provide postoperative outcome data derived from routine clinical follow-up, with no prospective recruitment or intervention.

Temporomandibular disorders (TMD) are one of the most important Public Health issues in the world and its incidence has increased over the years. The Physiotherapy and manual therapy techniques has shown its efficacy to reduce pain and to improve jaw functionality in patients with TMD. Until now, treatment targets has been the muscle and joint, but clinicians has not taken into account the innervation and how the nerve can have an influence in pain or jaw functionality. In this sense, it is known that there is a relationship between jaw innervation and vagus nerve, a parasympathetic nerve which is easily stimulable, due to its connection with the respiratory system, taking deep breaths using the diaphragm. Therefore, our hypothesis is that a treatment in which clinicians combine manual therapy and nerve vagus stimulation could have better effects (reducing pain, increasing range of motion in temporomandibular joints and improving quality of life in patients with TMD) than a isolated manual therapy treatment. With this purpose will be selected 20 subjects to participate in our study divided in two groups. Both groups will received 4 sessions of physiotherapy (one each 7 days during one month) and also will be thought to do own treatment those days the subjects does not come to the clinic until the study will have finished (the interventional period last two months). Both groups will received the same manual therapy techniques but only the experimental group will be treated with nerve vagus stimulation technique. One member of the group who will not participated in the interventions will be in charge of do evaluations (1 each month/ a total of 3 evaluations) following different questionaries to assess the primary variables of the study: chronic pain level, jaw functionality, physical symptoms level, range of motion and distress level.

The objective of the study is to evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) in improving pain in patients with TMD pain after 5 weeks of treatment, 1 month and 3 months after the end of treatment. As secondary objectives, we plan to evaluate the effectiveness of focal shockwave therapy in relation to: 1. Range of motion (ROM) of the temporomandibular joint using goniometry after 5 weeks of treatment; 2. Degree of inflammation, using ultrasound evaluation in the temporomandibular joint relating to the degree of pain after focal shockwave therapy for 5 weeks; 3. Jaw movement (MM), joint noise (RA), joint pressure (PA) and disability index (DI) will be measured at each treatment session and after 5 weeks of treatment, 1 month and 3 months after the end of treatment in the affected joints; 4. Quality of life will be assessed using the "Short Form Health 36" questionnaire (SF-36) during the 5 weeks of treatment, 1 month and 3 months after the end of treatment; 5. Pain control medication will also be considered and compared before and after the proposed treatment for 5 weeks. Safety will be assessed throughout the study by monitoring the incidence of study-related adverse events. All patients will be contacted periodically and encouraged to report any side effects.

The aim of this study is to investigate the relationship between Temporomandibular Disorders (TMD) and subjective tinnitus at both morphological and functional levels. Current literature suggests that somatosensory inputs from the temporomandibular joint (TMJ) and masticatory muscles can modulate auditory pathways, a phenomenon known as Somatosensory Tinnitus. However, the specific role of TMJ bone morphology and critical neighboring structures, such as the Petrotympanic Fissure (PTF), in this interaction remains unclear. In this clinical study, patients with tinnitus will undergo a comprehensive evaluation including Cone Beam Computed Tomography (CBCT) to quantitatively analyze condylar morphology and osteoarthritic changes. Additionally, audiological tests will be performed to assess the functional state of the auditory system. This multidisciplinary approach aims to clarify the biological link between TMD and tinnitus, potentially improving diagnostic protocols and highlighting the importance of TMJ stabilization in tinnitus management.

The purpose of this study is to test if the translated Arabic version of the (jaw functional limitation scale -8) JFLS\_8 , valid (face, content, feasibility) ,reliable (internal consistency, test retest) and culturally adapted enough to quantify the impact of temporomandibular joint (TMJ) disorders on jow function in arabic people or not?

This randomized, single-blind controlled trial aims to investigate the effectiveness of Body Awareness Therapy (BAT) on pain, functional limitations, and psychosocial outcomes in individuals with temporomandibular joint disorders (TMD). TMD is characterized by orofacial pain, impaired jaw function, and increased psychosocial burden, yet current physiotherapy approaches may not fully address the biopsychosocial mechanisms underlying these symptoms. BAT is a structured mind-body physiotherapy intervention designed to improve postural awareness, interoceptive sensitivity, breathing regulation, and movement control. In this study, participants will be randomly assigned to either BAT or a standard physiotherapy control intervention for a defined treatment period. Primary outcomes will include pain intensity and jaw functional limitations, while secondary outcomes will assess body awareness, anxiety, stress, and quality of life. Evaluations will be conducted at baseline and post-intervention. The findings of this trial may provide evidence for integrating biopsychosocial and awareness-based physiotherapy into TMD rehabilitation.

Goal: This clinical study aims to investigate how the range of motion of the temporomandibular joints (TMJ) changes in relation to the patient's head posture. Furthermore, we will assess the efficacy of a specific physiotherapy program in improving TMJ mobility and influencing head alignment in patients undergoing orthodontic treatment or prosthetic reconstruction. Scope: The project will evaluate TMJ function and head alignment in orthodontic or prosthetic patients aged 11-65. The core focus is to analyze the correlation between head posture and TMJ mobility and to measure changes in these parameters before and after the manual physiotherapy intervention.

This research involves retrospective and prospective studies for clinical validation of a DystoniaNet deep learning platform for the diagnosis of isolated dystonia.

This study relies on the use of a smartphone application (SOMA) that the investigators developed for tracking daily mood, pain, and activity status in acute pain, chronic pain, and healthy controls over four months.The primary goal of the study is to use fluctuations in daily self-reported symptoms to identify computational predictors of acute-chronic pain transition, pain recovery, and/or chronic pain maintenance or flareups. The general study will include anyone with current acute or chronic pain, while a smaller sub-study will use a subset of patients from the chronic pain group who have been diagnosed with chronic low back pain, failed back surgery syndrome, or fibromyalgia. These sub-study participants will first take part in one in-person EEG testing session while completing simple interoception and reinforcement learning tasks and then begin daily use of the SOMA app. Electrophysiologic and behavioral data from the EEG testing session will be used to determine predictors of treatment response in the sub-study.

This planned randomized, single-blind clinical trial will investigate the effects of adding the Post-Isometric Relaxation (PIR) technique to a standard postural exercise program in individuals with moderate to severe temporomandibular joint dysfunction (TMD). Forty volunteers aged 18-25 years will be recruited and randomly assigned to either an experimental group (postural exercises + PIR) or a control group (postural exercises only). The intervention will be delivered three times per week for six weeks. Primary outcomes will include cervical range of motion, mandibular mobility, head anterior tilt, and thoracic kyphosis index, measured before and after the intervention. The study aims to determine whether PIR provides additional benefits to standard postural exercises in improving jaw and neck function and postural alignment in young adults with TMD.

The purpose of this study will be to evaluate the effect of laser therapy on lateral pterygoid muscle in patients with Wilke's stage I and II temporomandibular disorders (TMD).

According to published literatures, the prevalence of TMD is approximately 10% in patients over 18 years of age with a considerable proportion being women of reproductive age. The treatment of TMD presents the following goals: decreasing joint and masticatory muscle pain, increasing the range of motion in the mandible, preventing degenerative changes in the articulating tissues. Management of TMD can be either conservative or surgical treatments, the conservative treatments include analgesia, medications, physical therapy, occlusal adjustment, splint therapy, localized steam application, and external muscle massage. The occlusal splint therapy is considered a common treatment option for TMD management. Flat stabilization splint is the preferred splint for such cases. It is designed to promote occlusal stability and decrease muscles tension by altering occlusion and allowing complete seating of the condyle in centric relation. The evolution of digital technology created new era of dentistry that successfully digitalized the traditional workflow of occlusal splints including designing and manufacturing. Furthermore, virtual facebow and dynamic jaw relation record using jaw tracking device are another digital reward. The digital workflow can offer more predictable approach for occlusal splint construction, It could eliminate the traditional technical errors and enhance the occlusal accuracy

This is a long-term (10 years), retrospective-prospective, observational, single-arm, monocenter study of patients to be treated with the Materialise TMJ Total Arthroplasty System for TMJ replacement. The study will evaluate the efficiency, safety, clinical performance, accuracy, benefits, and risks associated with long-term use and the impact on life quality and diet of the TMJ system, its fixation devices, TMJ Implant trial, and guides in the adolescent and adult populations.

Temporomandibular disorder or TMD is characterized by a set of symptoms such as: pain, decreased range of motion and joint noise. It's origin is multifactorial, which may be related to biological aspects, environmental and psychosocial. The multimodal approach has been widely used in physiotherapy for the treatment of TMDs. Physiotherapy has been walking together with technology so that telerehabilitation can be a reality, contributing so that quality care reaches the patient, in the impossibility office-to-face service. The objective of this study is to verify the effect of telerehabilitation on pain outcomes, range of motion, functionality and biopsychosocial aspects in individuals with temporomandibular disorders. Will be a randomized, controlled and blinded clinical trial was carried out. The study will be divided into two moments: evaluation and intervention. Evaluations will be carried out using the Diagnostic Criteria for Temporomandibular Disorders: Clinical Protocol and Assessment Instruments (DC/TMD), the Fonseca Anamnesis Index (IAF), the Numerical Pain Scale (END) and the Functional Limitation Questionnaire (MFIQ). Individuals will be randomized into 2 groups: Group A (in person) Group B (telerehabilitation). Both groups will receive treatment physical therapy for 12 weeks. After collecting the data, they will be tabulated and analyzed using a 5% significance level.

Temporomandibular disorder (TMD) refers to a group of musculoskeletal conditions that affect the temporomandibular joint (TMJ), the masticatory muscles, and the associated structures. It is assumed that 30 to 40% of cases of acute painful TMD becomes chronic. Chronic pain is a significant public health problem, affecting professional and social activities, emotional state, and quality of life. The pathophysiological mechanisms involved in chronic orofacial pain are complex and multifaceted and not yet fully understood. The coexistence of psychological factors associated with vast peripheral and central mechanisms makes chronic orofacial pain treatment a complex challenge. Due to the complexity of chronic TMDs, some patients remain refractory to current therapeutic methods. Thus, several efforts have been made to develop therapies aimed at the treatment of neuroplastic changes induced by chronic pain. In this sense, transcranial stimulation methods appear to be a promising technique. Transcranial Magnetic Stimulation (TMS) is a non-invasive, safe, and approved treatment for clinical use in psychiatric disorders such as depression and chronic pain. Given the above, it is necessary to develop studies to investigate the TMS effectiveness in chronic TMD. This study aims to evaluate the effectiveness of transcranial magnetic stimulation in patients with chronic temporomandibular disorders. An additional objective is to determine possible predictors for treatment success based on the assessment of functional brain connectivity and psychosocial characteristics.

Aim of the study was to compare the efficacy of internal versus external photobiomodulation (PBM) in the management of patients with TMJ internal derangements (TMJ-ID).

The aim of our study is to evaluate temporomandibular joint (TMJ), cervical posture, balance, dual-task performance, and social adaptation skills in individuals with autism. The study will be conducted at Bartın Lider Special Education and Rehabilitation Center following the approval of the ethics committee. Individuals determined by the sample size calculated through power analysis will be included in the study. First, the socio-demographic characteristics (age, height, body weight, body mass index, education level, exercise and smoking habits, etc.) of the participants who voluntarily join the study will be recorded. Participants will be divided into two groups: individuals with typical motor development and those with autism spectrum disorder (ASD), and the same assessment tools will be used for both groups. Individuals with typical motor development will serve as the control group. The assessment tools include the Timed Up and Go (TUG) test, the 10-Meter Walk Test, the Vineland Adaptive Behavior Scale, the PostureScreen Android-based posture assessment application, and the Helkimo Clinical Dysfunction Index for craniomandibular disorders. Based on the evaluation results, the relationships between TMJ, cervical posture, functional balance, dual-task performance, and social adaptation skills in individuals with autism will be analyzed and compared with those of individuals with typical motor development.

The goal of this clinical trial is to investigate the possible role of levonorgestrel intrauterine system use(LIU) in the pathogenesis of temporomandibular joint disorder (TMD). In this clinical trial, levonorgestrel intrauterine system patients (n=30) aged 25-50 and control group patients (n=30) with the same demographics and age range are used. The main questions it aims to answer are: To compare the frequency of temporomandibular dysfunction in women using the levonorgestrel intrauterine system with the control group of the same demographic and age range. The levonorgestrel intrauterine system use group consisted of 50 women who had previously a mirena implanted by a gynecologist at least 3 months ago due to menstrual bleeding and pelvic pain. The control group included 50 randomised healthy women who had regular menstrual cycles and were not taking any medication.
