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






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






3. Mandibular molars and maxillary molars are even






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






5. Guidance for protrusive occ should be on the






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






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






8. Above occlusal plane






9. Maxillary - Mandibular - Facial






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






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






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






13. Difference between primary and secondary occ trauma






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






15. Functional occlusion






16. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






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






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






19. #10 & #23






20. Relationship of the arches bone to bone;






21. Starts closer to premolars






22. 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






23. Introduced the concept of codestruction






24. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






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






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






27. Mandible moves to the right or left






28. Tongue thrust or thumb sucking can cause






29. 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






30. Tooth positioned more facial






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






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






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






34. Retrognathic profile






35. Starts around the mesial of the 1st molar






36. Maxillary-between canines and laterals - mandibular-between canines and 1st molars






37. What is not affected by occ trauma






38. Overlap of anterior teeth






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






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






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






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






43. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






44. Maxillary overlap mandibular; whole arch






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






46. Vibrational mvmt of a tooth under occ function






47. Tooth positioned more lingual






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






49. Below occlusal plane






50. Crowns tipped lingually - roots tipped laterally
