Lifespan of Splints in a Sample of German Soldiers Hospitalised with Post-traumatic Stress Disorder (PTSD) in Combination with Sleep Bruxism and Painful Temporomandibular Disorder (TMD).

PURPOSE: This cross-sectional longitudinal observational study aimed to clarify the question of whether painful temporomandibular disorders (TMD) in psychiatrically confirmed patients hospitalised for post-traumatic stress disorder (PTSD) therapy after using splint therapy (ST) show long-term therapeutic effects in the case of functional disorders. MATERIALS AND METHODS: One hundred fifty-three (153) inpatients (123 male and 20 female soldiers, age 35.8 ± 9.2 years, 26.6 ± 2.2 teeth) with confirmed PTSD (Impact of Event Scale - Revised ≥33), grade 3 to 4 chronic pain according to von Korff's Chronic Pain Scale and the research diagnostic criteria of painful TMD (RDC-TMD) were recorded. All participants received a maxillary occlusal splint that was worn at night. Control check-ups of the therapeutic effect of the splint were conducted for up to 9 years during psychiatric follow-ups. RESULTS: TMD pain worsened in 22 (14.4%) patients within the first 6 weeks and led to the removal of the splint. The pain intensity (PI) at BL was reported to be a mean of VAS 7.7 ± 1.1. Six weeks after ST (n = 131), the average PI was recorded as VAS 2.6 ± 1.3. Based on the last examination date of all subjects, the average PI was recorded as 0.7 ± 0.9. Seventy-two (72) patients used a second stabilisation splint in the maxilla after 14.4 ± 15.7 months, and 38 patients used between 3 and 8 splints during their psychiatric and dental treatment time (33.7 ± 29.8 months). CONCLUSION: The presented data shows that therapeutic pain reduction remained valid in the long term despite continued PTSD. The lifespan of a splint seems to be dependent on individual factors. Long-term splint therapy appears to be accepted by the majority of patients with PTSD and painful TMD.

Knowledge and awareness about temporomandibular disorder among dentists in India: Questionnaire study and review.

AIM: Temporomandibular disorders (TMD) comprise ailments involving the jaw joint (temporomandibular joint) and its associated anatomical structures. The complexity involved in TMD is primarily due to its broad spectrum of conditions, clinical signs and symptoms variability, and multifactorial etiology. Considering the above, the present study was performed to help understand the prevailing knowledge and awareness of TMD among Indian dentists in the context of the new specialty "orofacial pain". SETTINGS AND DESIGN: Questinnaire study and review. MATERIALS AND METHODS: The questionnaire was distributed using a web-based portal nationwide among Indian dentists. Dentists were invited to participate, clearly stating that the intent and purpose of the questionnaire was to record the existing knowledge and awareness concerning temporomandibular disorders among Indian dentists. The questionnaire was segregated into three sections: pathogenesis, diagnosis, and management of TMDs. The questions were recorded using a Likert three-point scale (1=agree; 2=disagree; 3=not aware). 310 dentists participated in the survey, among which 105 were general dentists (BDS [Bachelor of Dental Surgery] graduates), and 205 were dentists with specialist training (MDS [Masters of Dental Surgery] graduates). STATISTICAL ANALYSIS USED: The results obtained from the study participants was used to calculate the percentage and frequency, following which tabulations were made based on graduate type and clinical experience. The values obtained from all three sections were recorded, and the responses were analysed using Pearson's Chi-Square test with statistical significance kept at P < 0.05. RESULTS: Results of the study disclosed that only 58.1% of general dentists and 46.8% of specialists were confident in handling temporomandibular disorder patients. Splint therapy was the preferred treatment modality for general dentists, whereas dentists with specialist training preferred occlusal rehabilitation. CONCLUSION: The results of the current survey indicate that Indian dentists lack sufficient training in dental schools on all three sections and face difficulty diagnosing and treating TMDs.

Stabilisation Splint versus Other Conservative Therapies for the Treatment of TMD: A Systematic Review.

The purpose of this systematic review was to compare the effectiveness of stabilisation splint (SS) with other conservative treatment modalities in the management of temporomandibular disorders (TMD). An electronic search in PubMed, Google Scholar, and Cochrane was conducted to find randomised control trials published on the management of temporomandibular disorders in English language from March 2000 to June 2023 along with manual search in the relevant Journal of Prosthetic Dentistry, the American Journal of Prosthodontics, and the Journal of Oral Rehabilitation. A total of 64 studies were initially considered, out of which eight studies fulfilled the inclusion criteria. Furthermore, RoB-2 analysis tool was used for checking the risk of bias in the included studies. On comparing the readings and outcomes, only one study showed that the SS was better than the comparators. The review identified that there is weak evidence of effectiveness of SS splint therapy over other conservative therapies for the treatment of TMD. Key Words: Splints, Conservative treatment, Pain measurement, Temporomandibular disorders.

[Improvement of the mastication function of orthodontics combined with restoration in the treatment of deep overbite with severe lower anterior teeth attrition].

PURPOSE: To observe the effect of orthodontics combined with restoration on masticatory function in deep overbite patients with severe lower anterior teeth attrition. METHODS: From January 2018 to January 2022, a total of 164 deep overbite patients with severe lower anterior teeth attrition were collected and divided into two groups according to different treatment plans: control group(72 patients, with restoration treatment) and experimental group(92 patients, with orthodontics combined with restoration treatment). The chewing efficiency of the two groups was evaluated, temporomandibular joint dysfunction index (DI), muscle palpation index (PI) and cranio-mandibular index (CMI) were calculated. The satisfaction with facial esthetic, the Chinese version of Oral Health Impact Scale-14(OHIP-14) and the repair satisfaction score were evaluated, the occurrence of adverse events between the two groups was compared. SPSS 23.0 software package was used for statistical analysis. RESULTS: After treatment, the chewing efficiency of the experimental group was significantly improved compared to the control group, while the DI, PI, and CMI were significantly reduced compared to the control group(P＜0.05). Compared with the control group, the satisfaction degree with facial esthetic and restoration in the experimental group was significantly higher, while the OHIP-14 score was significantly lower after treatment(P＜0.05). The incidence of adverse events in the experimental group was significantly decreased compared with the control group (6.52% vs 25.00%, P＜0.05). CONCLUSIONS: Combination of orthodontics and restoration treatment can enhance the effectiveness of restoration treatment for deep overbite with severe lower anterior teeth attrition, improve the mastication function and temporomandibular joint balance,satisfaction and quality of life of patients, as well as reduce the risk of adverse events.

Evaluation of the efficacy and quality of life in patients with temporomandibular joint disorders treated with Kovacs digital occlusal splint: a pilot study.

BACKGROUND: Few studies have been conducted on treating temporomandibular disorders (TMDs) with new digital occlusal splints, which has increasingly attracted wide attention. METHODS: To evaluate the clinical efficacy and quality of life (QoL) of Kovacs digital occlusal splint (KDOS) treatment in patients with TMD. MATERIALS AND METHODS: Eighty-nine patients with TMD who were treated using KDOS were analyzed. The patients were divided into three groups according to the Wilkes stage. The clinical symptoms and QoL scores of the patients in each group were recorded before and at least three months after treatment, and the data were statistically analyzed and compared. The relationships between the disease severity, sex, age, and level of QoL before treatment and improvement in the clinical symptoms were analyzed using binary logistic regression. RESULTS: The mean age and follow-up period of the patients were 28.0 ± 10.4 years and 4.9 ± 2.1 months, respectively. After KDOS treatment, the improvement rates of joint noise and pain were 80.4% and 69.8%, respectively. Additionally, the patients' maximum mouth opening and global QoL mean scores significantly improved compared to those before treatment (p < 0.001). Binary logistic regression analysis revealed that the factors affecting the improvement in the clinical symptoms were disease severity and level of QoL before treatment. CONCLUSIONS: KDOS can improve the clinical symptoms and QoL of patients with TMD. Moreover, patients without osteoarthritis and with low pretreatment QoL levels are more likely to demonstrate clinical improvement. TRIAL REGISTRATION: The trial was registered with Chinese Clinical Trial Registry (ChiCTR) (ID: ChiCTR2300076518) on 11/10/2023.

[Research progress in mesenchymal stem cell-related therapies in the treatment of temporomandibular joint osteoarthritis].

Temporomandibular joint osteoarthritis (TMJOA) is a kind of organic disease with synovial inflammation, cartilage degeneration and subchondral bone remodeling as the main pathological changes. The current treatment is mainly to relieve symptoms, but cannot completely stop the progression of the disease. Mesenchymal stem cells (MSC) have multi-lineage differentiation potential and have good prospects in the repair therapy of TMJOA. Intra-articular injection of MSC from bone marrow, adipose, umbilical cord, dental pulp, etc. has been shown to be effective in numerous animal studies. The above exogenous MSCs can also be used as seed cells to participate in tissue engineering and repair more severe defects. Recent studies have shown that exosomes are important mediators of MSC action and have some potential in the treatment of TMJOA. As the mechanisms of TMJOA are further investigated, there is some prospect that endogenous repair capacity can be activated by local injection of relevant drugs targeting the resident stem cells in the joint.

Enkephalin Rescues Temporomandibular Joint Pain-Related Behavior in Rats.

Temporomandibular joint disorders include a variety of clinical syndromes that are difficult to manage if associated with debilitating severe jaw pain. Thus, seeking additional experimental therapies for temporomandibular joint pain reduction is warranted. Targeted enkephalin gene therapy approaches provide clear promise for pain control. The studies detailed here indicate significant analgesia and protection of joint tissue are provided after injection of an overexpression viral vector gene therapy near the joint. The viral vector gene therapy described provides overexpression of naturally occurring opioid peptides after its uptake by trigeminal nerve endings. The viral vectors act as independent "minipump" sources for the opioid peptide synthesis in the neuronal cytoplasm producing the intended biological function, reduction of pain, and tissue repair. The antinociceptive effects provided with this delivery method of opioid expression persist for over 4 weeks. This is coincident with the expected time frame for the duration of the transgene overproduction of the endogenous opioid peptide before its diminution due to dormancy of the virus. These experimental studies establish a basis for the use of replication-defective herpes simplex type 1-based gene therapy for severe chronic inflammatory temporomandibular joint destruction and pain. As innovative means of significantly reducing joint inflammation and preserving tissue architecture, gene therapies may extend their clinical usefulness for patients with temporomandibular joint disorders.

Study of axiography changes in patients with temporomandibular joint dysfunction.

OBJECTIVE: Aim: To determine the effectiveness of treatment of temporomandibular joints muscle and joint dysfunction with occlusive splints based on the analysis of axiography data. PATIENTS AND METHODS: Materials and Methods: 274 (two hundred and seventy-four) patients aged 18 to 44 years with a diagnosis of temporomandibular joints dysfunction before and after treatment. RESULTS: Results: All patients with signs of temporomandibular joints dysfunction before treatment had a violation of the movement trajectory of the lower jaw: deviation - 68.7%, diflexion - 31.3%. When opening and closing the mouth, asymmetric shifts of the lower jaw of more than 2 mm were observed. After treatment with occlusive splints, the correct trajectory of opening and closing the mouth was noted: the number of patients with a trajectory violation decreased by 89.1%, and the amount of displacement of the lower jaw during opening and closing the mouth in 92.4% of patients decreased on average to 0.9 mm. When analyzing the movements of the lower jaw in the sagittal plane, deviations of the trajectory of the lower jaw were found in 79% of clinical cases. After the treatment using occlusive splints, 93.4% of cases of mandibular movement trajectory violations in the transversal plane were eliminated, and 78.1% of patients had a reduction in displacement volume to 0.9 mm. When analyzing the movements of the lower jaw in the sagittal plane, deviations of the trajectory of the lower jaw were found in 79% of clinical cases. After the treatment using occlusive splints, 93.4% of cases of mandibular movement trajectory violations in the transversal plane were eliminated, and 78.1% of patients had a reduction in displacement volume to 0.9 mm. CONCLUSION: Conclusions: Movement trajectories of the lower jaw in the sagittal plane improved in 80.1% of patients, normalization of the position of the lower jaw in relation to the neuromuscular trajectory was achieved in 93.4% of clinical cases. According to the analysis of the parameters, this treatment should be considered effective.

Temporomandibular Disorders in Relation to Mandibular Advancement Devices for Treating Obstructive Sleep Apnea.

Mandibular advancement devices (MADs) keep the upper airways patent by holding the mandible and attached soft tissues forward via altered position of its condyles relative to the articulating surfaces of the temporal bones. During the first weeks of MAD therapy, pain may occur in the area of the temporomandibular joints, masticatory muscles, and/or teeth with a tendency of spontaneous resolution. In patients reporting temporomandibular disorder (TMD) symptoms prior to therapy, the MAD-related anterior condylar position during sleep may result in a reduction of TMD signs and symptoms.

The TMD management dilemma.

As temporomandibular disorders (TMDs) become ever more prevalent in both primary and secondary care settings, successful management is increasingly challenging in both sectors. The authors aim to explore the dilemma of TMD management as the patient journeys through from primary to secondary care and offer educational tools to support practitioners in managing this complex patient cohort, as well as outlining alternative solutions for the delivery of TMD management strategies.

Mesenchymal stem cells-derived exosomes alleviate temporomandibular joint disc degeneration in temporomandibular joint disorder.

Temporomandibular joint (TMJ) disorder (TMD) is a chronic progressive disease that is commonly seen in clinical settings. TMJ disc degeneration is an important manifestation of TMD, and further aggravates the progression of TMD. However, treatments on TMJ disc degeneration are very limited till now. In this study, we first observed the effects of bone marrow stem cells (BMSC) conditioned medium on functions of TMJ disc fibroblasts. Then BMSC-derived small extracellular vesicles (BMSC-EVs) were isolated and exposed to TMJ disc fibroblasts. RNA-sequencing was used to further investigate the mechanisms. BMSC-EVs were finally injected into a rat model with TMD. Results showed that in the transwell co-culture system, the medium derived from BMSC reduced inflammation and enhanced chondrogenesis in TMJ disc fibroblasts. BMSC-EVs promoted proliferation, migration, and chondrogenic differentiation of TMJ disc fibroblasts, and inhibited apoptosis and inflammatory responses. Local injection of BMSC-EVs into the TMD model alleviated TMJ disc degeneration. Therefore, BMSC-EVs were a potentially effective, sustainable and clinically translational-promising option for TMJ disc degeneration, and further reduce the progression of TMD.

Mesenchymal Stem Cell-Based Therapies for Temporomandibular Joint Repair: A Systematic Review of Preclinical Studies.

Temporomandibular disorders (TMDs) are a heterogeneous group of musculoskeletal and neuromuscular conditions involving the temporomandibular joint (TMJ), masticatory muscles, and associated structures. Mesenchymal stromal/stem cells (MSCs) have emerged as a promising therapy for TMJ repair. This systematic review aims to consolidate findings from the preclinical animal studies evaluating MSC-based therapies, including MSCs, their secretome, and extracellular vesicles (EVs), for the treatment of TMJ cartilage/osteochondral defects and osteoarthritis (OA). Following the PRISMA guidelines, PubMed, Embase, Scopus, and Cochrane Library databases were searched for relevant studies. A total of 23 studies involving 125 mice, 149 rats, 470 rabbits, and 74 goats were identified. Compliance with the ARRIVE guidelines was evaluated for quality assessment, while the SYRCLE risk of bias tool was used to assess the risk of bias for the studies. Generally, MSC-based therapies demonstrated efficacy in TMJ repair across animal models of TMJ defects and OA. In most studies, animals treated with MSCs, their derived secretome, or EVs displayed improved morphological, histological, molecular, and behavioral pain outcomes, coupled with positive effects on cellular proliferation, migration, and matrix synthesis, as well as immunomodulation. However, unclear risk in bias and incomplete reporting highlight the need for standardized outcome measurements and reporting in future investigations.

Comparative effects of post isometric relaxation technique and Bowen's therapy on pain, range of motion and function in patients with temporomandibular joint disorder.

BACKGROUND: The most common cause of mouth and facial pain is a temporomandibular joint disorder, which affects the patient's quality of life and interferes with their ability to perform daily tasks. OBJECTIVE: The purpose was to compare the effects of the Post-Isometric Relaxation Technique and Bowen's Therapy on pain, range of motion and functional activity in patients with temporomandibular joint disorders. METHODS: This study was a randomized clinical trial. A total of 24 participants were randomly allocated into two groups using the lottery method. Baseline treatment was the same (ultrasound and tapping) in both groups. Group 1 (12 participants) was treated with a post-isometric relaxation technique, and Group 2 (12 participants) with Bowen's therapy for two sessions per week (total duration of 4 weeks). Outcome measures were the Numeric Pain Rating Scale, Maximal mouth opening inter-incisal rural and jaw functional limitation scale-20. SPSS version 25 was used for statistical analysis. RESULTS: A significant improvement in pain, range of motions and functional activities in the post-isometric group showed significant results (p < 0.05) as compared to Bowen's group (independent t-test). However, within-group comparison (paired t-test), both groups showed significant results (p < 0.05). CONCLUSION: This study concluded that post-isometric relaxation was more effective in terms of pain, range of motions for mouth opening, lateral deviations and functional activity of temporomandibular joint disorder patients. However, both groups showed clinical results according to minimal clinical difference values. TRIAL REGISTRY NUMBER: The trial is registered under ClinicalTrials.govt with reference no. ID: NCT05392049 registered on 26/05/2022.

Evaluation of functional interaction masseter and sternocleidomastoid muscles affected by TMJ dysfunction.

OBJECTIVE: Aim: To evaluate the functional connection and the bioelectrical state of the m.masseter and m. sternocleidomastoid using functional tests before and after treatment. PATIENTS AND METHODS: Materials and Methods: The sample consisted of 21 individuals with temporomandibular joint dysfunction. Examinations were carried out before and after treatment using repositioning splint therapy and in seated/standing positions. RESULTS: Results: M. masseter - p=0.072 before treatment and p=0.821 after treatment. Symmetry is also maintained after treatment. After treatment, a significant difference is noted at the level of significance p<0.001 for the right chewing muscle. In seated and standing positions before treatment did not reveal a statistically significant difference (p=0.07, p=0.143) and after (p=0.272, p=0.623).M. sternocleidomastoid- p<0.001 when comparing right and left sides. After treatment, there was no difference between the right and left sides (p=0.169). No statistical difference was found when assessing indicators separately for the right and left muscles in seated and standing positions (p=0.304, p=0.611, p=0.089, p=0.869). When comparing the bioelectric potentials of the right muscle before, after treatment, a statistically significant difference was found p=0.001. CONCLUSION: Conclusions: Biostatistical analysis of the indicators of bioelectrical activity of m. masseter and sternocleidomastoid indicates no changes in muscle microvolt indicators with changes in body position in patients. However, repositioning splint therapy is associated with reduced muscle tone in initially more spasmodic muscles. It is worth noting that the symmetry of interaction between muscles improves.

How do Australian osteopaths manage migraines? Outcomes from a national practice-based research network.

BACKGROUND: Individuals who experience migraines often seek out a variety of treatment options including manual or physical therapy. Evidence suggests that manual therapy, including osteopathy, can play a role in the management of migraines. Whilst there is some literature on the role osteopathy therapy plays in migraine management, none describes the treatment approaches used by practitioners. OBJECTIVES: To explore the demographic, practice and clinical management characteristics of Australian osteopaths who report treating migraine 'often' in clinical practice. METHODS: Secondary analysis of a cross-sectional survey of 988 osteopaths from the Osteopathy Research and Innovation Network (ORION), an Australian practice-based research network. Regression analysis was used to identify demographic, practice and clinical management characteristics of Australian osteopaths who reported 'often' treating migraine patients. RESULTS: Over 40% of respondents (n = 400) indicated treating patients with migraines 'often'. These osteopaths were less likely to be involved in research and be co-located with a dietician compared to osteopaths who do 'not often' treat migraine. Osteopaths who reported 'often' treating migraine were: five times as likely to treat non-English speaking ethnic groups; 2.5 times as likely to treat chronic pain, temporomandibular joint disorders and hand musculoskeletal complaints; compared to those that do not treat migraines 'often'. CONCLUSION: Australian osteopaths who treat migraine are five times more likely to treat non-English speaking ethnic groups; twice as likely to treat chronic pain; temporomandibular joint disorders, and hand musculoskeletal complaints. More research is needed to identify the practices and patient outcomes associated with osteopathy care for those experiencing migraines.

Clinical effect of digitalized designed and 3D-printed repositioning splints in the treatment of anterior displacement of temporomandibular joint disc.

OBJECTIVE: To compare the treatment effectiveness of digitized and 3D-printed repositioning splints with that of conventional repositioning splints in the treatment of anterior displacement of the temporomandibular joint disc. METHODS: This retrospective study included 96 patients with disc displacement of the anterior temporomandibular joint. They were treated with either digitally designed and 3D-printed repositioning splints or traditional splints and followed up for at least six months. Changes in signs and symptoms such as pain and mouth opening before and after treatment were recorded to evaluate treatment outcomes. RESULTS: During the first month of treatment, both the digitally designed and 3D-printed repositioning splint groups (Group B) and the traditional repositioning splint group (Group A) showed significant increases in mouth opening, with increases of 4.93 ± 3.06 mm and 4.07 ± 4.69 mm, respectively, and there was no significant difference between the two groups. Both groups had a significant reduction in visual analog scale (VAS) pain scores, with Group B showing a greater reduction of 1.946 ± 1.113 compared to 1.488 ± 0.978 in Group A (P < 0.05). By the sixth month, Group B's mouth opening further improved to 38.65 ± 3.22 mm (P < 0.05), while Group A's mouth opening did not significantly improve. Regarding pain, Group A's VAS score decreased by 0.463 ± 0.778 after one month, and Group B's score decreased by 0.455 ± 0.715; both groups showed significant reductions, but there was no significant difference between the two groups. CONCLUSION: Compared with traditional repositioning splints, digitally designed and 3D-printed repositioning splints are more effective at reducing patient pain and improving mouth opening. 3D-printed repositioning splints are an effective treatment method for temporomandibular joint disc displacement and have significant potential for widespread clinical application.

TEMPOROMANDIBULAR JOINT DISORDERS AND THE WAY OF THEIR OPTIMIZATION: A LITERATURE REVIEW.

The literature review aims to investigate temporomandibular joint disorders and modern approaches to their treatment. An extensive literature search was performed using Scopus, ScienceDirect, and PubMed databases to identify the most relevant published articles. The year of publication was limited to over the past 5 years. The language was limited to English. More than 200 articles were found and analyzed. At first, abstracts were reviewed. After that 40 of the most relevant articles were selected and included. Systematical literature revision revealed that temporomandibular joint dysfunction is an essential public health issue worldwide due to its high prevalence and associated incapacity. Approximately one-third of the adult population worldwide suffers from at least one symptom of temporomandibular joint dysfunction. The etiology of this disease is considered to be multifactorial. Main risk factors include postural and parafunctional habits, several types of traumas, psychological distress, and occlusal factors. Temporomandibular disorder encompasses several pathological conditions. Based on the currently available evidence, chronic pain is frequently observed and results in lower quality of life. Proper diagnosis is crucial for successful treatment planning and outcomes of temporomandibular joint disorders. multidisciplinary treatment for the complete remission of all symptoms should be focused on the pain experience, jaw, and psychosocial functioning of the patients.

[Growth disturbances of the temporomandibular joint: causes, diagnosis and treatment]. / Groeistoornissen van het kaakgewricht: oorzaken, diagnose en behandeling.

Growth disturbances of the temporomandibular Joint are characterized by mandibular asymmetry, sometimes with secondary maxillar disturbances. Although the clinical symptoms are sometimes quite severe, patients usually have no pain. There are several growth disturbances, but in this article we discuss three particular causes of facial asymmetry, namely hemimandibular growth defects; overdevelopment, underdevelopment and neoplasms of the mandibular joint. Hemimandibular overdevelopment (hyperplasia) is a growth disorder characterized by progressive asymmetry of the mandibula. Hemimandibular hypoplasia, on the other hand, is a growth disorder involving underdevelopment of the condyle mandibulae due to impingement of the growth center and ankylosing. A pronounced asymmetrical face can cause aesthetic problems and always requires diagnostics, because in addition to the hyperplasia and hypoplasia mentioned above, other causes can explain the asymmetry such as, for example, an osteoarthritis or even a tumor emanating from the base of the skull, mandibula or soft tissues.

[Minimally invasive treatments and open joint surgery for disorders of the temporomandibular joint]. / Minimaal invasieve behandelingen en opengewrichtschirurgie voor aandoeningen van het kaakgewricht.

The initial treatment of symptomatic disorders of the temporomandibular joint typically consists of a conservative approach, in which medication (painkillers and muscle relaxants), orofacial physiotherapy and splints are most important. In most cases, minimally invasive treatment options, such as arthrocentesis, arthroscopy or joint injections, are only considered when conservative methods provide insufficient symptom reduction. There is, however, an ongoing debate about the optimal treatment strategy due to an increasing body of evidence concerning the superior effectiveness in symptom reduction of minimally invasive treatment options with regard to conservative treatments. If these minimally invasive treatment options are also ineffective, open joint surgery may be considered as a last option for a select group of patients.

Orthodontic camouflage treatment of a hyperdivergent adolescent patient with anterior open bite and TMD: a case report.

BACKGROUND: In orthodontics, anterior open bite is a common malocclusion that recurs frequently. Because the causes of anterior open bite are so varied, medical professionals must create customized treatment programs for each patient based on their unique etiology. Through the lowering of the posterior teeth, closure of the anterior teeth gap, and cooperation with intermaxillary traction, the treatment plan outlined in this case study sought to achieve a stable occlusion. CASE PRESENTATION: This case report aims to describe an orthodontic camouflage treatment of a 15-year-old female patient with anterior open bite, arch width discrepancy and a history of temporomandibular joint disorder. The patient was treated with intermaxillary vertical elastics and the multiple edgewise arch wire (MEAW) approach. A satisfactory occlusion with a neutral molar relationship was attained after 29 months of orthodontic therapy. The condylography recording showed that this patient's occlusion tended to be more stable both before and after our treatment. The purpose of this case study is to provide an overview of an orthodontic camouflage treatment for a female patient, who had a history of temporomandibular joint disease, anterior open bite, and arch width disparity. CONCLUSIONS: Our results demonstrated that more attention should be paid to levelling the occlusal plane, intrusion of the molars, decompression of temporomandibular joints and the etiology factors of malocclusion during the orthodontic period for those patients with anterior open bite.
