Background/Objectives: Tongue thrust (TT) occurs when abnormal tongue movements cause anterior tongue placement with pressure and contact against or between the teeth, potentially affecting the oral phase of swallowing, impacting eating, breathing and speaking. There is limited literature on the diagnostic and treatment approaches for TT, as well as involvement of health practitioners in its management. This study aims to examine the current knowledge and practices related to TT diagnosis and treatment among health professionals in Australia. Methods: A two-phase explanatory sequential mixed methods approach was adopted, comprising an online survey that collected participants’ demographic information and details on assessment, diagnosis, management, referral practices, and relevant experience and training. Phase one involved 47 health professionals from various disciplines in Australia who completed an online survey in its entirety. Phase two included in-depth interviews with seven speech-language pathologists (SLPs) to gain further insights into their experiences in managing TT. Survey data were analysed descriptively, and interview data was analysed thematically. Results: Most participants diagnosed TT using clinical assessments, such as general observation and oral motor examinations. Treatment approaches commonly included orofacial myofunctional therapy and the use of myofunctional devices. Interviews with SLPs identified four key themes: tongue thrust as a symptom rather than a diagnosis, facilitators to effective treatment, multidisciplinary approaches to management, and training and education gaps in clinical practice. Conclusions: This study provides valuable insights into how TT is identified, assessed, diagnosed, and managed by health professionals in Australia. It highlights the perspectives of SLPs on treatment approaches, as well as their views on the availability and adequacy of training and education in this field. The findings suggest the need for a broader understanding of TT management, emphasising the importance of multidisciplinary collaboration and professional development. These insights are globally relevant, as they stress the shared challenges and the value of international collaboration in improving TT diagnosis and treatment practices. Full article

Obstructive sleep apnea syndrome (OSAS) in children and adolescents is a prevalent and multifactorial disorder associated with significant short- and long-term health consequences. While adenotonsillectomy (AT) remains the first-line treatment, a substantial proportion of patients—especially those with obesity, craniofacial anomalies, or comorbid conditions—exhibit persistent or recurrent symptoms, underscoring the need for individualized and multimodal approaches. This review provides an updated and comprehensive overview of current and emerging treatments for pediatric OSAS, with a focus on both surgical and non-surgical options, including pharmacological, orthodontic, and myofunctional therapies. A narrative synthesis of recent literature was conducted, including systematic reviews, randomized controlled trials, and large cohort studies published in the last 10 years. The review emphasizes evidence-based indications, mechanisms of action, efficacy outcomes, safety profiles, and limitations of each therapeutic modality. Adjunctive and alternative treatments such as rapid maxillary expansion, mandibular advancement devices, myofunctional therapy, intranasal corticosteroids, leukotriene receptor antagonists, and hypoglossal nerve stimulation show promising results in selected patient populations. Personalized treatment plans based on anatomical, functional, and developmental characteristics are essential to optimize outcomes. Combination therapies appear particularly effective in children with residual disease after AT or with specific phenotypes such as Down syndrome or maxillary constriction. Pediatric OSAS requires a tailored, multidisciplinary approach that evolves with the child’s growth and clinical profile. Understanding the full spectrum of available therapies allows clinicians to move beyond a one-size-fits-all model, offering more precise and durable treatment pathways. Emerging strategies may further redefine the therapeutic landscape in the coming years. Full article

Background/Objectives: The study evaluated the effectiveness of Nuvola^® OP aligners, combined with an interceptive myofunctional device, in achieving dental arch expansions over an 18–26-month treatment period. Methods: 54 patients (31 women and 23 men, aged between 18 and 48 years old) participated in the study. The inclusion criteria for the present research were optimal oral hygiene, no prior orthodontic treatments, and no systemic conditions affecting outcomes of the treatment. Linear measurements (D1, D2, D3, D4) were obtained from STL files of the dental arches before and after treatment using Carestream CSMODEL™ software 3.10.47. Statistical analysis included MANOVA, Pearson’s correlation, and paired t-tests, following the Shapiro–Wilk test for data normality. Results: The treatment duration averaged 22.4 months. D1–D4 measurements means increased by 2.1 mm for D1, 2.37 mm for D2, 1.0 mm for D3, and 3.67 mm for D4. MANOVA results (p = 0.063) confirmed similar effects on all parameters, while Pearson’s correlation showed a weak positive association among distance changes. Conclusions: Nuvola^® OP aligners, used with an interceptive myofunctional device, effectively improved arch parameters. The significant increases in D1–D4 mean values suggest that this approach might be beneficial for controlled dental arch expansion in adult patients. Full article

Obstructive sleep apnea (OSA) is a heterogenous disease process that cannot be adequately categorized by AHI alone. There is a significant prevalence of OSA in the general population with ongoing efforts to evaluate the risk factors contributing to OSA and its associated clinical implications. Only by improving our understanding of OSA can we advance our methods in the diagnosis and treatment of OSA. For this article, the authors reviewed keywords of obstructive sleep apnea diagnosis and therapy in the databases of Embase, Medline, and Medline ePub over the past 3 years, excluding any articles that only addressed sleep apnea in children under age 17 years. This review article is divided into three main sections. First, we will investigate the use of novel screening tools, biomarkers, anthropometric measurements, and novel wearable technologies that show promise in improving the diagnosis of OSA. There is mention of comorbid conditions seen in OSA patients since certain disease combinations can significantly worsen health and should raise our awareness to diagnose and manage those concomitant disorders. The second section will look at the current and developing treatment options for OSA. These include positive airway therapy (PAP), mandibular advancement device (MAD), exciting new findings in certain medications, orofacial myofunctional therapy (OMT), hypoglossal nerve stimulation therapy (HGNS), and other surgical options. We will conclude with a section reviewing the current Clinical Practice Guidelines for Diagnostic Testing in Adults with Obstructive Sleep Apnea from 2017, which strongly advises polysomnography (PSG) or home sleep apnea testing (HSAT), along with comprehensive sleep evaluation for uncomplicated patients with a clinical presentation of OSA.

Elastodontics is an interceptive orthodontic therapy that uses light and biological elastic forces through preformed or custom-made removable orthodontic appliances. This study aims to evaluate the effects of elastodontic devices on correcting sagittal discrepancies in growing subjects with mixed dentition. Electronic research was conducted on four databases: PubMed, Scopus, EMBASE, and Web of Science. Data were extracted based on the first author, year of publication, setting and country, study design, sample characteristics, sample size calculation, type of malocclusion, intervention, control group type, compliance, follow-up, and cephalometric measurements. Sixteen studies were included in the final review. Most studies observed a statistically significant reduction (p < 0.05) in SNB and ANB angles. Ten studies reported a reduction in overjet, while eight studies found no change in facial divergence. Comparisons with conventional functional devices revealed no consensus on the skeletal and dentoalveolar effects. Elastodontic appliances significantly improve cephalometric and dentoalveolar parameters, potentially correcting skeletal and dental relationships. However, result variability and unclear advantages over traditional appliances highlight the need for further research. Full article

Background: Achondroplasia is a genetic condition that results in several orofacial and physical manifestations that predispose patients to dental, breathing, and sleep issues. Case Description: This report details the case of a 2-year-old girl with achondroplasia, malocclusion, speech and breathing dysfunction, and obstructive sleep apnea (OSA). Treatment involved using a myofunctional device that required chewing twice per day, two simple tongue exercises, speech-language therapy, chiropractic therapy, and continuous positive airway pressure (CPAP) for 24 months. Throughout the treatment period, the patient demonstrated significant improvements in her sleep, breathing, dental occlusion, speech, and overall confidence. Conclusion: This case report highlights how pediatric patients with achondroplasia can improve their OSA symptoms and health with conservative myofunctional therapy interventions.

This review aims to reveal the effectiveness of myofunctional speech therapy on facial rejuvenation and/or improvement of orofacial function. A systematic review of four medical electronic databases (Medline, Google Scholar, SciELO, and LILACS) was conducted between January and March 2023. The research question was defined using the PICO model: Population (P): adult subjects with signs of physiological aging of facial skin. Intervention (I): aesthetic speech therapy (facial exercises and/or myofunctional therapy). Control (C): absence of treatment. Outcome (O): facial rejuvenation. Through the search process, a total of 472 potentially relevant articles were identified. A total of 21 studies were included in the review. Most of the studies required the participants to perform exercises learned during the weekly session on a daily basis. The subjects underwent an integrated treatment with facial exercises and worked on the stomatognathic functions for different durations. Many differences were found in the evaluation tools used to investigate the starting situation and the effects obtained following the treatment. At the diagnostic level, there was no concordance in the choice of the most appropriate scales and assessment tools, but great heterogeneity was observed. Indeed, forty-eight percent of the studies collected objective data through the use of various instruments (oral devices, electromyographs, cutometers, muscle ultrasound scans, and laser scans of the face). The observed improvements included not only a reduction in wrinkles and frown lines but also decreased muscle tension and slackness, enhanced facial symmetry and lip competence, improved skin elasticity, and restored stomatognathic function. These changes led to myofunctional restoration and facial rejuvenation, resulting in increased satisfaction with self-image and proprioception. Full article

This case report describes an 18-year-old female patient with a skeletal class I pattern, mandibular asymmetry, a molar class III on the right side, a molar class II on the left side, and an anterior open bite (AOB). Treatment of AOB is often difficult for orthodontists and a multidisciplinary approach is sometimes required to rehabilitate the correct function and posture of the tongue. In this case the AOB was treated using the Nuvola^® OP System: a treatment system that combines orthodontic aligners and a myofunctional elastodontic device called Freedom. An upper molar intrusion with miniscrews was performed during the first phase of the treatment programme, and then the aligner treatment began. The Nuvola^® OP System ’s aligners are characterized by lingual pins that guide the tongue to the palatal spot position and take advantage of tongue function. The patient was instructed to wear the Freedom device for 30 min a day and to clench every 3 s with closed lips while wearing the aligners. These exercises improve the fitting of the aligners, improve the tongue’s posture, and take advantage of the masticatory forces to resolve the malocclusion. The patient was successfully treated, thus demonstrating that the Nuvola^® OP System is a valid alternative for the treatment of AOB. Full article

Obstructive sleep apnea syndrome (OSAS) is the most common breathing-related sleep disorder. It is characterized by recurrent episodes of partial or complete airway obstruction during sleep, resulting in a reduction in or the total cessation of airflow, despite ongoing respiratory efforts, leading to oxygen desaturation and arousal. The purpose of this literature review is to evaluate the most common characteristics of this pathology, as well as to investigate the most effective treatment options, providing an update on the management of OSA patients.

Purpose: Poor oral health is a known predictor of aspiration pneumonia in vulnerable populations such as the elderly and chronically ill. This study examined the feasibility of using myofunctional devices during a 5-week intervention for the management of oral care and dysphagia for residents in a residential aged-care facility. Method: Feasibility was determined through evaluation of study recruitment and retention rates, adherence to intervention, and resident and staff acceptability of the intervention. Thirteen residents, ages 74–99, participated in the intervention and 10 care staff completed feedback on post-intervention questionnaires. Results: Enrolment and retention rates were 61.9% and 92.3%, respectively. Adherence rates for use of the device were 92.6% at 3 weeks, and 89.3% at 5 weeks for the 12 participants who completed the protocol. The device was considered acceptable for ease of use, comfort, and amount of support required. Conclusion: Results indicate that further research exploring device use in an aged care population for the management of dysphagia and oral hygiene is feasible. Full article

Obstructive sleep apnea (OSA) is a clinical disorder within the spectrum of sleep-related breathing disorders (SRDB) which is used to describe abnormal breathing during sleep resulting in gas exchange abnormalities and/or sleep disruption. OSA is a highly prevalent disorder with associated sequelae across multiple physical domains, overlapping with other chronic diseases, affecting development in children as well as increased health care utilization. More precise and personalized approaches are required to treat the complex constellation of symptoms with its associated comorbidities since not all children are cured by surgery (removal of the adenoids and tonsils). Given that dentists manage the teeth throughout the lifespan and have an important understanding of the anatomy and physiology involved with the airway from a dental perspective, it seems reasonable that better understanding and management from their field will give the opportunity to provide better integrated and optimized outcomes for children affected by OSA. With the emergence of therapies such as mandibular advancement devices and maxillary expansion, etc., dentists can be involved in providing care for OSA along with sleep medicine doctors. Furthermore, the evolving role of myofunctional therapy may also be indicated as adjunctive therapy in the management of children with OSA. The objective of this article is to discuss the important role of dentists and the collaborative approach between dentists, allied dental professionals such as myofunctional therapists, and sleep medicine specialists for identifying and managing children with OSA. Prevention and anticipatory guidance will also be addressed. Full article

The purpose of the present study was to evaluate the mechanical resistance of elastodontic devices (ED): their maximum compression loads and plastic deformation under loading (percentage). An Instron universal machine (Model 3365, Instron, Industrial Product Group, Grove City, PA, USA) was employed with a 100 N load cell and with Bluehill software for loading analyses. Each device was submitted to a five-cycles test. The following ED were evaluated: A.M.C.O.P. (Micerium, Genova, Italy) in red color, in orange color, and in blue color; HealthyStart (Ortho-Tain, Winnetka, IL, USA), and T4K™ phase 1 (Myofunctional Research Co., Helensvale, Australia). During the five-cycles test, the Ortho-Tain device delivered the greatest compression load (7.56 N), with the lowest percentage of deformation (0.95%). For all devices, a slight plastic deformation of the material was registered, ranging from 0.95% to 1.75%. For the T4K device it was not possible to complete the five-cycles test. For all the analyzed ED, a slight plastic deformation under loading was registered, that in all cases can be considered clinically acceptable. Further studies are needed to test the appliances after clinical usage. Full article

Adult orthodontic patients with skeletal Class III malocclusion, open bite and bimaxillary dentoalveolar protrusion are complex problems that normally require surgical intervention to correct. This is a report of an adult female with a skeletal Class III jaw relationship; in addition, the patient had anterior open bite and bimaxillary dentoalveolar protrusion. The patient also had three premolars in the lower left quadrant. Treatment involved extracting the extra premolar distal to lower left canine, retraction of lower anterior teeth, closing extraction space and anterior open bite utilizing Invisalign clear aligners. The patient initially changed aligners every week before this was changed to 3–5 days after starting to use a high frequency vibration (HFV = 120 Hz) device. Satisfactory results were achieved in a relatively shorter period. Comparing before and after treatment cone beam computed tomography revealed that new bone has been formed labial to the lower incisors after their retraction/correction of their initial proclined position and the use of HFV and myofunctional therapy without gingival graft. The present case report shows the comprehensive multidisciplinary team approach in treatment for such cases and the advantage of using HFV to improve bone formation. Full article

PURPOSE: To investigate the motivation and the effects of: tongue movement direction; resistance force level; repetition number; and sustained tongue contraction duration on tongue motor performance in healthy pre-teen children using computer games. METHODS: An analytical observational cross-sectional study was conducted with 15 healthy 11–13 year-old children with normal lingual strength. The participants played six computer games using a tongue-controlled joystick. The series varied the time for continuous force application on the target (3 and 5 s) and the target force level (0.5, 1 and 2 N). After the tests, the participants answered a questionnaire about their impressions and reactions to the game. The variables analyzed were number of attempts to score (NAS), time for which the target force was maintained (TTFM), and the time spent for scoring (TSS). RESULTS: Of 43 normally developing candidates screened for the study, 15 (35%) were included for having entirely normal tongue structure and function and for being able to complete all of the study tasks. Of the 15 participants, 11 (73.3%) said that it was easy to play, three (20.0%) found it a bit hard to play, and only one (6.6%) considered it difficult to play. The results suggest that healthy individuals with normal lingual structure and function are able to successfully perform the games, but those with longer durations of sustained contraction (5 s) and the most required force (2 N) are the most difficult. Leftward and upward movements were more difficult than rightward and downward movements. CONCLUSION: All of these carefully selected participants were able to perform all of the study tasks, indicating that this method is feasible for pre-teens with normal lingual structure and function. The joystick device encouraged the participants to perform tongue movements that may be part of the typical orofacial myofunctional treatment exercises for tongue function. Results indicated that this game has the potential to be highly motivating for pre-teen children who are able to perform the tasks. Full article
