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.
1. Mandible moves to the right or left






2. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






3. Max canine occludes with mand. canine and mand. 1st premolar.






4. Mvmt of the mandible in a direction anterior to centric occ






5. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






6. Vertical overlapping






7. Relationship of the teeth in opposite arches; static position






8. Maxillary anterior teeth stick out labially from tongue thrusting






9. II (mal)occlusion






10. Need tooth to tooth contact on both working and non working sides to func effectively






11. Mandibular molars more distal than maxillary molars






12. Curved alignment of the occlusal plane when looking from a posterior view(right to left)






13. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






14. Malposition - crowded anterior teeth - protruded or retruded max incisors - anterior/posterior crossbite - mesial drift






15. Tongue thrust or thumb sucking can cause

17. Maximum interlocking of cusp






18. Mandibular molars and maxillary molars are even






19. Laterally






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

22. After periodontal sugery - mobility will ________






23. Maximal intercuspation or contact of the max and mand teeth






24. Maxillary incisors are are lingual to mandibular incisors






25. Lateral mvmt results in contact btwn the max and mand canines






26. Difference between primary and secondary occ trauma






27. Curve of the occlusal plane; from anterior to posterior - increases with age






28. Contact between maxillary incisors does not line up with contact of mandibular incisors






29. Tongue thrusting; thumb sucking - pacifiers






30. The side to which the mandible moves(chewing side)

37. Prognathic profile






38. Selective grinding should always be completed after ______ has been controlled






39. When no teeth are contacting on this side






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