Dentistry Quiz

What is the neutral zone in the oral cavity primarily determined by?

• Musculature of the cheek

• Musculature of the jaw

• Musculature of the lips

• Musculature of the tongue

Why is the neutral zone important in prosthodontics?

• To ensure maximum occlusal contact

• To conform to the horizontal position determined by the neutral zone

• To determine the vertical position of teeth

• To prevent tooth decay

What are compensating curves used for in dentistry?

• To determine the color of artificial teeth

• To develop balanced occlusion

• To shape the waxed up denture bases

• To reduce the size of artificial teeth

Which type of compensating curve is the Curve of Spee?

• Anteroposterior compensating curve

• Mediolatral compensating curve

• Vertical compensating curve

• Horizontal compensating curve

What is the significance of the Curve of Spee?

• To determine the vertical relationship of teeth to the occlusal plane

• To prevent disocclusion when the mandible moves forward

• To aid in seating the denture

• To allow for maximum occlusal contact in lateral movements

What should the central fossa of the mandibular posterior teeth be aligned with?

• The center of the crest of ridge

• The tip of the lower canine

• The anterior border of the ramus

• The buccal cusps of the premolars

Which cusps of the maxillary and mandibular posterior teeth are considered functional?

• Maxillary buccal cusps – mandibular buccal cusps

• Maxillary palatal cusps – mandibular buccal cusps

• Maxillary lingual cusps – mandibular lingual cusps

• Maxillary buccal cusps – mandibular lingual cusps

What is the purpose of waxing up in dentistry?

• To reduce the size of artificial teeth

• To clean the teeth surface

• To contour the trial denture bases

• To extract teeth

Why should the lingual flanges of the waxed up denture be concave?

• To increase the thickness of the palate

• To aid in denture retention

• To interfere with tongue movements

• To produce a perfect peripheral seal

What should the palate of the waxed up denture be like?

• Thin and uniform

• Convex and smooth

• Thick and irregular

• Concave and rough
