• Aligning the teeth without adjusting the jaw

Definition of Malocclusion: What is the definition of malocclusion in orthodontics?

• Improper alignment of the upper and lower teeth when biting

• Discoloration of teeth

Distinguishing Class II Malocclusion: Class II malocclusion is divided into two divisions, 1 and 2. What is the primary difference between these two divisions?

• Division 1 features an overjet, while Division 2 features an underbite

• Division 1 features protruded upper front teeth, while Division 2 features retroclined upper front teeth

• Division 1 is characterized by a crossbite, while Division 2 is characterized by an open bite

• There is no significant difference
