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. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






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






3. Maxillary - Mandibular - Facial






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






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






6. Occlusal guard =






7. Cervical 3rd






8. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






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






10. #7 - 26 - 27






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






12. Habitual - acquired - convenience - intercuspal & static






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






14. Tooth extracted






15. 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






16. Maxillary incisors are are lingual to mandibular incisors






17. II (mal)occlusion






18. Above occlusal plane






19. Relationship of the teeth in which the incisal ridges of the maxillary anterior teeth extend below the incisal edges of the mandibular anterior teeth when the teeth are placed in a centric occlusal relationship






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






21. Mandible moves to the right or left






22. #10 & #23






23. Functional occlusion






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






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






26. Mandibular molars more distal than maxillary molars






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






28. Both sides






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






30. Middle 3rd






31. Prognathic profile






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






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






34. Posterior; no horizontal overlap






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






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






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






38. What is not affected by occ trauma






39. Mesially - Labially






40. When the jaws are closed - the buccal cusps of the mandibular posterior teeth are interlocked between the buccal & lingual cusps of the maxillary teeth






41. Lateral mvmt results in contacct of all posterior teeth






42. Difference between primary and secondary occ trauma






43. ____ is not a sign of occl trauma






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






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






46. The permanent molars erupt posterior to the primary teeth and push them all mesially






47. When no teeth are contacting on this side






48. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts






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






50. Incisal 3rd
