Dentistry Occlusion

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

14. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






15. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth

20. Prognathic profile






21. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






22. Associated with performance; all contacts during function of the oral cavity






23. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






24. Because the permanent premolars are narrower than the primary molars that they replace - this is what happens when the premolars erupt
