Dr. SamsonGERALD S. SAMSON, D.D.S., Diplomate of the American Board of Orthodontics (ABO), Fellow of the American College of Dentists (FACD).  Dr.  Samson completed pediatric dental residency at Emory University in 1979 and orthodontics at Northwestern University in 1981. In addition to orthodontic private practice, Dr. Samson holds formal faculty appointments at seven postgraduate programs and has lectured extensively.


As primary care providers of pediatric dentistry, all of us prefer to base our treatments on evidence-based principles. We yield to that obligation. As professionals we strive to provide accurate information to parents whose children present with occlusal relationships that, if left untreated, may lead to conditions that can be both unattractive, dysfunctional, and become more severe.

In this informative and entertaining course, Dr. Samson will cover treatment options and strategies that will help any dentist improve their knowledge of orthodontics.

Learning Objectives

  • What are the potential consequences of advising to not treat the anterior and/or posterior cross-bite and wait until all the permanent teeth are in occlusion?
  • Clinically, what are the most effective anterior and posterior cross-bite correction appliances and how are they adjusted by the doctor?
  • What is the best method to correct a true unilateral cross-bite?
  • When confronted with an anterior cross-bite, which are true Class III problems with eventual ortho-surgical potential?
  • What are the best post-treatment retention methods?
  • Which patients have the highest cross-bite relapse potential; what factors are responsible for the relapse and what can be done about that risk?
  • What are the evidence based consequences of bicuspid extraction and non-extraction?  Which are true “borderline extraction” patients?
  • Prior to treatment, which specific orthodontic records and informed consent forms are needed?
