Temporomandibular joint (TMJ) dysfunctions are conditions in which there is a disruption in the anatomical and functional relationship between the various structures of the joint, including the articular disc, intra-articular ligaments, mandibular head and capsule. These disorders have a negative impact on the patient’s quality of life, resulting in limitations in masticatory function and articulation. The multifactorial nature of this pathology emphasizes the need for an individualized and comprehensive approach to the treatment of each patient. In most cases, treatment includes both surgical and orthopedic methods. Currently, combined treatment approaches aimed at synergistic effects are being actively developed to maximize therapeutic Results.The purpose of this study. To evaluate the efficacy of the combination of treatment with a repositioning mouthguard and the use of the hydraulic articular disk repositioning method in patients with internal TMJ disorders combined with dental row end defects.Materials and methods. The study included 6 patients with TMJ dysfunction and end defects of the dentition. The study was conducted between September 2023 and May 2024. As part of the study, each patient underwent cone beam computed tomography (CBCT) to evaluate the bony structures of the TMJ and ultrasound (US) to evaluate the soft tissue structures of this joint.Results. The CBCT data showed that the mean posterior temporomandibular joint displacement before treatment was 1.67, while this value increased to 3.02 after treatment. The US results showed a significant decrease in the mean value of mandibular head displacement after treatment ranging from 0.21 to 0.03, indicating a positive effect of treatment. In addition, there was a decrease in the difference in the size of the anterior and posterior parts of the articular disc, confirming the elimination of its displacement.Conclusion. The treatment combination of using a repositioning mouth guard with the hydraulic repositioning method brought about a synergistic effect on the restoration of TMJ function.

This rapid review summarizes the latest primary research in temporomandibular joint (TMJ) injection treatment. The final literature searches were conducted on 4 January 2024. Selection was performed systematically following predefined eligibility criteria. Randomized control trials concerning the treatment of TMJ disorders with intra-articular injections were included. Studies on more invasive interventions were excluded. Quality of life, joint pain and range of mandibular mobility were assessed. Ultimately, 12 studies covering a total of 603 patients qualified. They concerned: (1) arthrocentesis (AC) and the administration of, (2) injectable platelet-rich fibrin (I-PRF), (3) platelet-rich plasma (PRP), (4) hyaluronic acid (HA), (5) non-steroidal anti-inflammatory drugs (NSAIDs), and (6) hypertonic dextrose (HD) with a local anesthetic. The dominant approach was to perform arthrocentesis before administering the appropriate injection substance (I-PRF, PRP, HA, or NSAID). Two current studies on the intra-articular administration of NSAIDs, specifically tenoxicam and piroxicam, are noteworthy. A mixture of PRP and HA was injected in another two trials. These two innovative approaches may prove to be significant directions for further research on injection treatment of TMJs.
Objectives: This review aimed to gather and summarize the existing information on the clinical application of allogeneic umbilical and placental derivatives in the treatment of temporomandibular joint disorders. Methods: Research on the impact of the use of umbilical and placental derivatives on reducing pain and improving mobility in the temporomandibular joint was included in the article. Medical databases, including ACM, BASE, Cochrane, Scopus, Google Scholar, ClinicalTrials.gov, and PubMed, were searched. The final search was conducted on 20 October 2024. Results: Out of the 43 records found, 5 were considered eligible for further analysis and showed that the use of placental and umbilical derivatives has the greatest potential in the treatment of ankylosis. The intra-articular administration of these tissues into the TMJ brings beneficial results, but they are similar to other, parallel methods, such as PRP or corticosteroids. Conclusions: The studies discussed may guide researchers in expanding clinical trials, particularly by including more patients with TMDs, and have promising potential in ankylotic disorders, where amniotic membrane use has shown clear benefits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
