What influences the final arrangement of the arch in complete dentures?
The pressure of the cheeks and tongue against the facial and lingual surfaces of the erupting natural teeth
What is the solution to positioning the posterior teeth in complete dentures?
Position the teeth along a line extending from the tip of the canine to the middle of the retromolar pad
Which of the following is true about the amount of curvature developed in complete dentures?
It rarely requires more than a combined 20-degree elevation of the occlusal surfaces of the posterior teeth.
What is the purpose of the anteroposterior compensating curve in complete dentures?
To provide the needed tooth structure for balancing contacts in the protrusive movement.
