2011 Annual Session - Early Class III Treatment: What are the Nonsurgical Limits? / Camouflage Class III Treatment Using Temporary Skeletal Anchorage

Credits: None available.

Early diagnosis by general dentists and enhanced parental awareness bring many Class III patients to the orthodontist at a younger age than was done with previous generations. As a result, orthodontists are frequently required to develop a diagnosis and treatment plan when the patient still has a primary or mixed dentition. This paper will present an effective treatment strategy for Class III patients who are initially seen between the ages of 4 and 10. One of the key goals of early intervention of the Class III patient is reducing the need for jaw surgery; this presentation will conclude with an assessment of 100 consecutively treated Class III patients between the age of 4 and 10. Evidence based guidelines will be presented that demonstrate an acceptable cephalometric threshold range for Class III patients who can be effectively managed non-surgically.

Learning Objectives:

  • Differential diagnosis of the Class III skeletal problem using key cephalometric indicators.
  • Effective therapeutic measures that emphasize compliance, sutural activation, inter-incisal correction, and periodic assessment of growth vectors.
  • A method of assessing treatment response that differentiates the non-surgical Class III and the surgical Class III patient.
  • A method of discussing treatment progress that allows both the patient and parent to be presented with appropriate informed consent.

Camouflage Class III Treatment Using Temporary Skeletal Anchorage

Most of us who use protraction facemasks in treating developing Class III malocclusions with deficient maxilla will encounter anchorage loss such as mesial movement of maxillary molars and incisors. The speaker will address whether this anchorage loss can be prevented with the help of TAD or miniplates. Another opportunity in normalizing a mild to moderate skeletal Class III malocclusion is to camouflage using extraction or non-extraction treatment. The speaker will illustrate with cases on whether the use of miniscrews can simplify the biomechanics of distalizing the lower arch or retracting the lower anterior segment in extraction cases.

Learning Objectives:

  • How to camouflage Class III malocclusions with early orthopedic treatment
  • How to camouflage Class III malocclusion with extraction and non-extraction treatment
  • How to use TAD to simplify the biomechanics of treating Class III cases
