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. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






2. After periodontal sugery - mobility will ________






3. Anterior; no horizontal overlap






4. What is not affected by occ trauma






5. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






6. Maximum interlocking of cusp






7. Growth hormone imbalance that causes the mandible to grow faster than the maxilla(all teeth are in crossbite)






8. Difference between primary and secondary occ trauma






9. Laterally






10. Tooth positioned more lingual






11. Measurement of horizontal overlap w/ probe






12. 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






13. Maxillary overlap mandibular; whole arch






14. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






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






16. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






17. Abnormal contacts; occlusal habits - and neuroses






18. Mandibular molars and maxillary molars are even






19. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






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






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






22. During protrusive occ - ______ is considered undesirable






23. Posterior; no horizontal overlap






24. Horizontal






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






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






27. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






28. Middle 3rd






29. Vertical overlapping






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






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






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






33. Symptom free dentition that 'survives' or 'adapts' to a deviated occl






34. The tooth has insufficient bone support and normal chewing and swallowing forces are excessive - causing injury to the attachment appartatus






35. Tooth extracted






36. Mesognathic profile






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






38. Maxillary incisors are are lingual to mandibular incisors






39. Later






40. #7 - 26 - 27






41. Cervical 3rd






42. Vertical






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






44. If the mandible moves to the left - the mvmt is known as a left working movement






45. Tooth positioned more facial






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






47. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






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






49. Mandibular molars more distal than maxillary molars






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