Study Notes
Classification of Occlusion
- Skeletal classification is based on the relationship of the bone of the maxilla to the bone of the mandible.
- Dental classification is based on the relationship of the teeth of the mandible to the teeth of the maxilla.
Angle's Classification System
- This system is based primarily on the relationship of the permanent first molars.
- It is the most popular classification system used in dentistry today.
- It allows for different classifications on each side.
- A Class I occlusal relationship is characterized by the lingual cusps of the maxillary teeth positioned in the buccal groove of the mandibular teeth.
- A Class II occlusal relationship is characterized by the maxillary teeth being positioned anterior to the mandibular teeth.
- An ideal Class I occlusion is defined by the maxillary teeth being positioned slightly anterior to the mandibular teeth.
- In an ideal Class I occlusion, the buccal cusps of the maxillary crown should be positioned in the buccal groove of the mandibular teeth.
Skeletal Classification
- Class I skeletal classification describes a normal relationship between the maxilla and mandible.
- Class II skeletal classification is characterized by a retrognathic mandible (maxillary teeth positioned anterior to the mandibular teeth).
- Class III skeletal classification is characterized by a protruded mandible.
Occlusion Stability
- Occlusion is most stable when the teeth are in a position of maximum intercuspation.
Other Facts
- Pulp exposure is caused by excessive wear or decay.
- There is no classification system based on the relationship of the pulp to the surrounding tissues.
