Transverse skeletal deficiencies in orthodontics: etiology, consequences and treatment approaches

Aim: This paper explores the etiology, consequences, and treatment strategies for transverse skeletal deficiencies in orthodontics, focusing on treatment duration and growth prediction models. Materials and Methods: A comprehensive literature review encompassed embryological development, environmental factors, clinical presentations, and treatment strategies for transverse skeletal deficiencies. Studies on craniofacial growth, orthodontic interventions, surgical approaches, and Elastodontic therapy were analyzed. Results: Transverse skeletal deficiencies arise from genetic, intrauterine, and postnatal factors such as pacifier use, thumb-sucking, mouth breathing, and insufficient maxillary expansion during childhood. These deficiencies commonly lead to dental malocclusions, posterior crossbites, and airway issues, including sleep-disordered breathing. Traditional treatments like rapid maxillary expansion (RME) and surgical-assisted rapid palatal expansion (SARPE) are effective for younger and older patients. In addition, Elastodontic therapy, which utilizes elastic-based appliances to improve the alignment and function of the maxilla, offers a non-invasive, patient-friendly alternative for managing transverse deficiencies. This approach benefits cases requiring slower, more gradual expansion, providing better long-term stability than other methods. Treatment duration typically ranges from three to six months for younger patients, with more extended retention periods in older patients to prevent relapse. Conclusions: Transverse skeletal deficiencies are influenced by genetic, intrauterine, and environmental factors, leading to functional and aesthetic concerns, such as malocclusions and compromised airway function. Early intervention, including methods like orthopedic expansion and Elastodontic therapy, offers promising results, while surgical approaches are necessary for more severe cases. Understanding the developmental trajectory of these deficiencies is essential for tailoring treatment plans and ensuring both functional and aesthetic improvements. Future research should refine growth prediction models and evaluate the long-term effectiveness and stability of Elastodontic therapy in managing transverse skeletal deficiencies.
