HOSA Dental Terminology Practice

Angle's Classification is primarily based on the relationship of which teeth?

1. Permanent molars and canines

2. Incisors and canines

3. Deciduous molars and incisors

4. Permanent incisors only

The correct answer is: Permanent molars and canines

Angle's Classification is primarily based on the relationship of the permanent molars and canines. This classification system was developed by Dr. Edward Angle in the early 20th century and is used to categorize malocclusion, or misalignment of teeth. The key focus in Angle's Classification is how the first permanent molars, specifically the maxillary first molar and the mandibular first molar, align relative to each other, as well as the position of the canines. This system helps in diagnosing and planning orthodontic treatment by providing a clear framework for understanding different types of bite relationships, such as Class I, Class II, and Class III malocclusions. Therefore, the relationship between these specific teeth is essential in determining proper dental occlusion and alignment.
