Cusp Placement: Marginal Ridge Occlusion (Upper Jaw)
This section details the placement of cusps in the upper jaw to achieve a marginal ridge top occlusion.
- First premolar: Distal fossa of the first premolar.
- Second premolar: Distal fossa of the second premolar.
- First molar: Mesio-lingual cusp, central fossa of first molar.
- First molar: Disto-lingual cusp, distal marginal ridge of the first molar and mesial marginal ridge of the second molar.
- Second molar: Mesio-lingual cusp, central fossa of the second molar.
- Second molar: Disto-lingual cusp, distal marginal ridge of the second molar.
Cusp Placement: Cusp to Fossa Occlusion (Upper Jaw)
This section describes cusp placement in the upper jaw for a cusp to fossa occlusion.
- First premolar: Distal fossa of the first premolar.
- Second premolar: Distal fossa of the second premolar.
- First molar: Mesio-lingual cusp, central fossa of first molar.
- First molar: Disto-lingual cusp, distal fossa of first molar.
- Second molar: Mesio-lingual cusp, central fossa of the second molar.
- Second molar: Disto-lingual cusp, distal fossa of the second molar.
Cusp Placement: Marginal Ridge Occlusion (Lower Jaw)
This section focuses on cusp placement in the lower jaw for a marginal ridge top occlusion.
- First premolar: Mesial marginal ridge of the first premolar.
- Second premolar: Distal marginal ridge of the first premolar and the mesial marginal ridge of the second premolar.
- First molar, mesiobuccal cusp: Distal marginal ridge of the second premolar and the mesial marginal ridge of the first molar.
- First molar disto-buccal cusp: Central fossa of first molar. First molar distal cusp, usually non-functional.
- Second molar, mesiobuccal cusp: Distal marginal ridge of the first molar and the mesial marginal ridge of the second molar.
- Second molar disto-lingual cusp: Central fossa of the second molar.
Cusp Placement: Cusp to Fossa Occlusion (Lower Jaw)
This section details cusp placement in the lower jaw for a cusp to fossa occlusion.
- First premolar: Mesial fossa of the first premolar.
- Second premolar: Mesial fossa of the second premolar.
- First molar, mesiobuccal cusp: Mesial fossa of first molar.
- First molar disto-buccal cusp: Central fossa of first molar.
- First molar distal cusp: Distal fossa of first molar.
- Second molar, mesiobuccal cusp: Mesial fossa of the second molar.
- Second molar disto-buccal cusp: Central fossa of the second molar. Second molar distal cusp, usually non-functional.
