Study Notes
Overjet and Overbite Measurements
- Normal overjet range: 1 to 3 millimeters.
- Abnormal overjet values are typically considered to be greater than 3 millimeters, indicating potential alignment issues.
Tooth Occlusion Relationships
- In a normal dental arch relationship, the mesiobuccal cusp of the maxillary first permanent molar occludes with the buccal groove of the mandibular first permanent molar.
- The typical range for overbite is 2 to 4 millimeters, with overbites measured vertically.
Occlusion Types
- Correct occlusion pattern occurs when all teeth interdigitate properly; this is also identified as a Class I occlusion.
- If the mesiolingual cusp of the maxillary first permanent molar occludes correctly, it indicates appropriate positional alignment with the corresponding mandibular tooth.
Clinical Indicators
- An overbite of 5 millimeters would be characterized as deep or increased overbite, often indicative of dental or skeletal discrepancies.
- In a normal occlusion, the correct positioning of the maxillary teeth is crucial for proper function and esthetics in a healthy dental arch relationship.
