A 22 year-old patient presents to you seeking correction of a bilateral posterior cross bite secondary to a constricted maxilla. How would you proceed? Would you attempt dental expansion, RPE (Rapid Palatal Expansion), MARPE (Mini-screw Assisted Rapid Palatal expansion), SARME (Surgically-Assisted Rapid Maxillary Expansion), or perhaps MPMO (Multiple Piece Maxillary Osteotomy)? This case-based clinical lecture will review the literature and present current research data from the University of Iowa to help you make this decision.
Understand the considerations for choosing the appropriate treatment approach for maxillary expansion in non-growing individuals.
Understand the limitations of each treatment approach.
Evaluate the University of Iowa laboratory technique for manufacture of MARPE appliances.
