What is the correct sequence of preparations in occlusal rest seats?
What is the correct sequence of preparations in occlusal rest seats?
- Occlusal rest seat preparation followed by proximal preparation
- It does not matter which preparation is done first
- Both preparations can be done simultaneously
- Proximal preparation followed by occlusal rest seat preparation (correct)
What happens when proximal preparation follows occlusal rest seat preparation?
What happens when proximal preparation follows occlusal rest seat preparation?
- The marginal ridge becomes too high and rounded
- The marginal ridge becomes too low and too sharp (correct)
- The center of the floor of the rest seat moves away from the marginal ridge
- The rest preparation becomes impossible to correct
Why is it often impossible to correct the rest preparation?
Why is it often impossible to correct the rest preparation?
- Because the marginal ridge is too high
- Because the proximal preparation was done incorrectly
- Because the center of the floor of the rest seat is too close to the marginal ridge (correct)
- Because the rest seat is too deep
