Understanding Dental Occlusion Concepts

The video tutorial explains dental terminologies such as misal, distal, buckle, and lingual, and describes the occlusal surface of teeth. It introduces Angle's classification of occlusion, detailing Class I, II, and III occlusions with diagrams. Class I is considered normal occlusion, Class II involves a protruded maxilla and retruded mandible, and Class III features a prognathic mandible and retruded maxilla.

Which part of the tooth is oriented towards the midline?

• Mesial

• Distal

• Lingual

• Buccal

Which part of the tooth faces the buccal mucosa?

• Lingual

• Distal

• Mesial

• Buccal

What is the term for the part of the tooth oriented towards the tongue?

• Mesial

• Lingual

• Distal

What is the surface of the teeth that contacts the maxillary teeth called?

• Distal surface

• Buccal surface

• Occlusal surface

• Lingual surface

In Class I occlusion, where does the cusp of the maxillary first molar align?

• With the buccal groove of the mandibular first molar

• With the mesial groove of the mandibular first molar

• With the distal groove of the mandibular first molar

• With the lingual groove of the mandibular first molar

What is another name for Class II occlusion?

• Normal occlusion

• Prognathism

• Retrogenia

• Crossbite

In Class II occlusion, how is the maxillary first molar positioned relative to the mandibular first molar?

• Distal

• Buccal

• Mesial

• Lingual

What is the characteristic feature of Class III occlusion?

• The maxillary first molar's cusp is lingual to the mandibular first molar

• The maxillary first molar's cusp is mesial to the mandibular first molar

• The maxillary first molar's cusp is distal to the mandibular first molar

• The maxillary first molar's cusp is buccal to the mandibular first molar

What is another term for Class III occlusion?

• Normal occlusion

• Prognathism

• Retrogenia
