Study Notes
Mandible Anatomy
- The temporalis muscle attaches to the coronoid process.
- The mental foramen allows the inferior alveolar nerve and artery to exit the mandibular canal.
- The lateral pterygoid muscle is responsible for protraction of the mandible.
- Elevation is the movement of the mandible that closes the mouth.
- The mental nerve innervates the skin of the lower lip and the front of the chin.
Mandible Structure
- The mandible is commonly known as the jawbone.
- The mental foramen is located near the roots of the lower premolars.
- The digastric muscle attaches medially at the digastric fossa.
- The alveoli are the parts of the mandible that lodge the teeth.
- The mental protuberance forms the shape of the chin in the mandible.
Dental Terminology
- The term for the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin is erosion.
- The diastema is the open space found between the upper incisors.
- The overbite is the term for the extent of the vertical overlap of the maxillary central incisors over the mandibular central incisors.
- The occlusal relationship forms when teeth erupt and meet their antagonist in the opposite arch.
- A working tooth is a tooth that articulates during occlusion with a tooth in the opposing jaw.
- The centric relation is the relationship between the maxillary and mandibular teeth when they approach each other as occurs during chewing or at rest.
- Attrition is the wearing away of the tooth structure by mechanical forces from opposing teeth through contact of its functioning surfaces.
- The overjet is the extent of the horizontal overlap of the maxillary central incisors over the mandibular central incisors.
