What is the optimal crown-to-root ratio for FPD abutment teeth? - 2:3 is the OPTIMAL ratio 1:1 is the maximum acceptable ratio (You can't have more crowns than roots supporting it) (E.g. 2 abutment teeth with 3 roots total) What is Ante's law? - Abutment teeth root surface are should be equal to or more than replaced/pontic teeth (e.g. A pontic tooth that would normally have 2 roots should have at least 2 (preferably more) roots on abutment teeth.) How does deflection (bend) change for 2-tooth vs 3-tooth pontics? - If span length is doubled (e.g. 1 tooth to 2 tooth), deflection (bend) will be 8x more. (number of teeth in the pontic cubed = deflection) (E.g. 2-tooth = 8x (2^3), 3-tooth = 27x (3^3)) What planes should the abutment teeth be parallel to each other to have effective path of insertion and draw? - Facial plane, buccal plane, and occlusal/incisal plane Describe the different pontic designs? Which do we use at UDM? - Hygenic design: Non-mucosal contact Conical design: Small tip, can collect debris
