Study Notes
Development of Occlusion
- Primary dentition, mixed dentition, and permanent dentition are the stages of occlusion development
- Class I, II, and III occlusion and space maintainers are essential concepts in occlusion development
Classifications of Occlusion
- Class I: Normal occlusion, ideal relationship between upper and lower teeth
- Class II: Upper teeth are more forward than lower teeth
- Class III: Lower teeth are more forward than upper teeth
- End on Class II: A type of Class II occlusion where the upper and lower teeth meet at the edges
Moyers Mixed Dentition Analysis
- A method to predict space available for permanent teeth in mixed dentition
- Measures the size of unerupted canines and premolars from the mesiodistal widths of mandibular incisors
Primate Spaces
- Normal spacing found in primary dentition to accommodate the width of wider permanent teeth
- Maxilla: Space between lateral and canine
- Mandible: Space between canine and first molar
Terms in Occlusion
- Overbite: Vertical overlap of maxillary teeth over mandibular teeth
- Overjet: Horizontal overlap of maxillary teeth over mandibular teeth
- Physiologic Occlusion: Ideal occlusion, Class I, promotes health and good function
- Pathological Occlusion/Traumatic Occlusion: Causes destruction of periodontium and wear of teeth
- Mixed Dentition: Phase when some teeth are primary and some are permanent
- Leeway Space: Difference between the space available for permanent teeth in the mixed dentition and the space required for the permanent teeth
Problems with Space
- Too much space: Large jaw and/or small teeth
- Too little space: Small jaw and/or large teeth

Description
This quiz covers the different classifications of occlusion, including Class I, Class II, and Class III, and their characteristics. It also touches on the development of anteroposterior (AP) problems in mixed dentition.
