Study Notes
Tooth Junction Terminology
- The junction of the mesial, buccal, and occlusal surfaces of a molar is referred to as the "point angle."
- The junction of the mesial, lingual, and incisal surfaces of anterior teeth is also called a "point angle."
- In tooth morphology, the junction of mesial, distal, and incisal surfaces of a tooth is known as a "corner junction."
Drawing and Carving of Teeth
- The subject of drawing and carving teeth is introduced to improve understanding of tooth morphology and its practical applications in dentistry.
- Figure 1-14 illustrates the specific angles depicted for posterior teeth, focusing on their distinctive geometry.
Specific Types of Angles
- The rounded mesial and distal incisal angles of anterior teeth are categorically named "incisal angles."
- A "point angle" is specifically formed at the junction of three surfaces of a tooth.
- The mesioincisal line angles and distoincisal line angles are considered "rounded" due to the curvature of the incisal angles in anterior teeth.
Division and Highlighted Angles
- In the division into thirds, exemplified in Figure 1-13, a specific point angle is highlighted that represents significant anatomical detail.
- A line angle is designated when discussing the junction of the lingual and incisal surfaces, contributing to a more comprehensive understanding of anterior tooth structure.
