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. Most common cause is when the maxilla does not grow in proportion to the mandible






2. Starts closer to premolars






3. Survival of the dentition despite its deviation from a preconceived hypothetical normal






4. Normal contacts between max. and mand. teeth; momentary contacts






5. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






6. Laterally






7. Buck teeth are common and are considered






8. Incisal 3rd






9. Guidance for protrusive occ should be on the






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






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






12. A continuation of the spee of to extend through the condyle






13. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






14. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






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






16. Introduced the concept of codestruction






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






18. Anterior; no horizontal overlap






19. Cusps of maxillary teeth directly over cusps of mandibular teeth






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






21. Mandibular molars more mesial than maxillary molars (most children)






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






23. Aquired centric occlusion - habitual occlusion - convienience occlusion - or intercuspal position






24. Maxillary overlap mandibular; whole arch






25. Abnormal contacts; occlusal habits - and neuroses






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






27. Horizontal






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






29. Habitual - acquired - convenience - intercuspal & static






30. Mandible moves to the right or left






31. Muscles that work the jaw; may become sore due to occ trauma






32. Class III (mal)occlusion of permanent teeth






33. Occlusal guard =






34. 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






35. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






36. Tooth positioned more lingual






37. Above occlusal plane






38. Radiographically - the PDL space is wider at the coronal third of the root






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






40. #10 & #23






41. Tongue thrust or thumb sucking can cause






42. Anterior or posterior; bilateral or unitlateral - anterior more common






43. Mesially - Labially






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






45. Tongue thrusting; thumb sucking - pacifiers






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






47. Vertical






48. Tooth positioned more facial






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






50. Transverse occlusal curvature; posterior teeth; medio-lateral postion (r-l)
