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. Curve spee & wilson - 3-d - not proven






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






3. Below occlusal plane

5. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






6. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






7. Mb cusp of max 1st molar-buccal groove of mand 1st molar






8. Slight buccal inclination of crown - lingual inclination of root

13. Tooth positioned more facial






14. Individual teeth from each arch can be involved in ________________ malocclusion






15. Both sides






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






17. During a left working movement - the right side is known as the






18. Maxillary incisors are are lingual to mandibular incisors






19. Functional occlusion






20. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






21. Tooth positioned more lingual

23. #10 & #23






24. The way you normally bite your teeth together when not chewing






25. Usually indicative of moderate to sever perio and secondary occ trauma






26. Horizontal distance of anterior teeth in crossbite






27. Excessive deposition of cementum around the apex - due to excessive occlusal forces






28. Anterior; no horizontal overlap

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






32. Patients show evidence or signs and syptoms of occ disease

39. Mandibular molars and maxillary molars are even






40. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






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

46. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






47. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious
