Maxillary Expansion: Removable Appliances, MARPE, and Surgically Assisted Rapid Palatal Expansion (SARPE)
Maxillary Expansion: Removable Appliances, MARPE, and Surgically Assisted Rapid Palatal Expansion (SARPE)
Course overview
Maxillary expansion requires precise diagnosis and an individualized choice of protocol taking into account the patient's age, the degree of transverse deficiency, and the condition of the palatal suture. Errors at the diagnostic stage can lead to selecting inappropriate appliances, insufficient expansion, or treatment complications.
This course is dedicated to the modern approach to diagnosing and treating transverse deficiencies of the maxilla — from analysis of digital models and CBCT to appliance selection and surgically assisted expansion.
Within the course you will learn:
Diagnosis of transverse deficiencies of the maxilla using digital models and CBCT, including the Penn method
Features of assessing maxillary width in growing patients
Assessment of the palatal suture condition and its significance for treatment strategy selection
Protocols for maxillary expansion in children and adolescents
Choice between tooth-borne appliances and skeletal anchorage (MARPE)
Appliance activation parameters, combination with other orthodontic appliances, and result monitoring
Indications and clinical protocols for SARPE
Typical errors and complications with different methods of maxillary expansion.
The course will help you build a sequential algorithm — from diagnosing transverse deficiency to selecting the optimal expansion method and monitoring its outcome.
