8. The correct answer is C. Lingualized articulation. Lingualized articulation is not a type of complete denture articulation. The other options, balanced articulation, linear or monoplane articulation, and canine-protected articulation, are all types of complete denture articulation.<br /><br />9. The correct answer is B. Soft palate. The posterior palatal seal is seen in the soft palate. It is a type of seal that is used to prevent air and food from passing through the nasal cavity during swallowing.<br /><br />10. The correct answer is D. All of the above. Mandibular complete denture should cover the retromolar pad because it provides a better retention, provides a border seal, and resists movement of the denture base.<br /><br />11. The correct answer is B. Hamular process. In determining the posterior limit of a maxillary denture base, the hamular process is on the posterior border.<br /><br />12. The correct answer is B. Flabby ridges. Selective pressure impression technique is indicated in flabby ridges. This technique is used to record the shape of the ridge and the surrounding tissues.<br /><br />13. The correct answer is C. Stippling. Stippling is defined as carving in the base material of a denture that simulates the contours of the natural tissues.<br /><br />14. The correct answer is D. Irreversible hydrocolloid. Irreversible hydrocolloid is used in a custom tray. It is a type of material that is used to make custom trays for impressions.
