Course overview

Big course on design, insertion, activation, and treatment workflow of surgical and miniscrew-assisted maxillary skeletal expanders (MSE)!

Aimed at orthodontic professionals, this course offers evidence-based approaches and all the clinical tips and protocols for both non-surgical and surgical maxillary expansion.

Course lessons

• Skeletal expander troubleshooting
• Aligner treatment planning for skeletal expanded cases
• Analysis of clinical cases.

Lesson 2: Maxillary Expansion: Diagnosis and Treatment Planning

• Anatomy of the maxillary bone and palatine bone
• Indications for maxillary expansion
• Etiology of maxillary constriction
• Differentiating between skeletal and dental crossbites
• Treatment philosophies:
• Slow maxillary expansion

• Advantages and disadvantages of surgically assisted rapid maxillary expansion (SARME)
• Clinical solutions to common side effects and errors that could occur during maxillary expansion
• Analysis of various expansion appliances and their protocols of application
• Radiographic analysis of before and after maxillary expansion
• Step-by-step analysis of clinical cases.

Lesson 4: Digital Workflow of MSE Appliance Design

• Surgical and non-surgical maxillary skeletal expansion (MSE) and its clinical applications
• Benefits of MSE in addressing maxillary deficiencies

Lesson 5: MSE Appliance Placement and Activation

• Step-by-step appliance insertion protocols
• Expansion protocols for children, adolescents, and adults
• Failures and complications: protocols for management and prevention
• Troubleshooting maxillary resistance to expansion
• Evaluation of the treatment process and radiographic assessment protocols.

Lesson 6: Clinical Application of MSE Appliances and Case Selection

• Case selection, diagnosis, and treatment planning
• Indications, clinical findings, and contraindications for maxillary skeletal expansion
• Step-by-step analysis of clinical cases: from diagnosis to post-treatment retention.

Lesson 7: RPE: From Diagnosis to a Predictable and Successful Result

• Diagnosis of transverse maxillary discrepancy
• Evaluation of midpalatal suture maturation
• Protocols for planning and placing miniscrews
• Hybrid vs. bone-borne appliances
• Limitations of the MARPE appliance and how to overcome them
