Basic Principles

Question 1

What kinds of treatment are available when severe skeletal discrepancies result in malocclusion?

Answer 1

1. growth modification
2. orthodontic camouflage
3. orthognathic surgery

Question 2

When should the treatment approach of growth modification be considered?

Answer 2

This treatment approach should only be considered for mild skeletal deformities

Question 3

How can growth modification in adolescents influence maxillary anteroposterior excess?

Answer 3

Excessive horizontal growth of the maxilla may be impeded by headgear or camouflaged by extraction of the maxillary first premolars and orthodontic retraction of the incisors

Question 4

How can growth modification in adolescents influence maxillary anteroposterior deficiency?

Answer 4

moderate improvement can be established by orthodontic protraction

Question 5

How can growth modification in adolescents influence vertical maxillary excess?

Answer 5

High-pull headgear with temporary anchorage devices can impede the vertical growth of the maxilla and diminish the severity of the deformity

Question 6

How can growth modification in adolescents influence mandibular anteroposterior deficiency?

Answer 6

Headgear combined with functional appliances may improve mandibular projection

Question 7

Which skeletal deformities cannot be easily influenced by growth modification?

Answer 7

• mandibular anteroposterior excess
• vertical maxillary deficiency
• microgenia

Question 8

What often happens when patients seek dental compensation for a skeletal deformity aka orthodontic camouflage?

Answer 8

• impaired esthetics
• questionable post-treatment stability
• prolonged treatment time

corrective treatment may require rebanding and a second orthodontic treatment followed by orthognathic surgery
