Chapter 3: Orthodontic Diagnosis and Treatment Planning
Summary:
This chapter discusses the process of diagnosing orthodontic problems, including the importance of taking a comprehensive medical and dental history. It covers various diagnostic tools, such as radiographs, study models, and photographs.
Example:
An orthodontic therapist records a patient's history and takes a cephalometric radiograph to assess head and jaw development. They analyze the results and contribute to the development of the treatment plan.
Chapter 4: Orthodontic Appliances
Summary:
This chapter describes different types of orthodontic appliances, including fixed and removable appliances, as well as their components. It covers the principles of appliance design and activation.
Example:

Chapter 6: Orthodontic Treatment Considerations
Summary:
This chapter explores the factors that influence orthodontic treatment, including age, dental health, and skeletal growth. It covers the principles of extraction therapy and the management of impacted teeth.

Chapter 8: Orthodontic Mechanics
Summary:
This chapter explains the biomechanical principles behind orthodontic tooth movement, including force systems, moments, and stresses. It covers the different techniques used to control tooth movement.
Example:
An orthodontic therapist calculates the appropriate force to apply to a patient's teeth using a calibrated appliance to achieve desired tooth alignment.
Chapter 9: Retention and Relapse Prevention
Summary:
This chapter discusses the importance of retaining the results of orthodontic treatment after the active phase is complete. It covers different types of retainers and the principles of relapse prevention.
Example:
An orthodontic therapist provides a patient with instructions on how to wear a removable retainer and schedules regular check-ups to monitor tooth position and prevent relapse.
