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






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






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






4. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






5. Class III (mal)occlusion of permanent teeth






6. Vertical overlapping






7. Retrognathic profile






8. Maxillary anterior teeth stick out labially from tongue thrusting






9. Laterally






10. 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






11. Mandible moves to the right or left






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






13. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






14. Mesognathic profile






15. After periodontal sugery - mobility will ________






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






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






18. Widening of the PDL in areas under pressure results due to






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






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






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






22. Tooth positioned more facial






23. Tooth extracted






24. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






25. Hereditary - Tongue - Intercuspation of teeth - Alignment of previously erupted teeth affects alignment of successive teeth






26. Horizontal distance of anterior teeth in crossbite






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






28. Difference between primary and secondary occ trauma






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






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






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






32. 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






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






34. Habitual - acquired - convenience - intercuspal & static






35. Crowns tipped lingually - roots tipped laterally






36. Maxillary - Mandibular - Facial






37. Lateral mvmt results in contacct of all posterior teeth






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






39. Vertical






40. Spaces between two teeth






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






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






43. Measurement of horizontal overlap w/ probe






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






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






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






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






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






49. Starts closer to premolars






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