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






2. Maxillary overlap mandibular; whole arch






3. Starts around the mesial of the 1st molar






4. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






5. Overlap of anterior teeth






6. Maxillary incisors are are lingual to mandibular incisors






7. Both sides






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






9. Later






10. Tooth positioned more facial






11. Tooth positioned more lingual






12. Horizontal






13. II (mal)occlusion






14. Mandibular molars more distal than maxillary molars






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






16. Excessive occ force with adequate bone support =






17. Introduced the concept of codestruction






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






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






20. Mandible moves to the right or left






21. Class III (mal)occlusion of permanent teeth






22. Maximum touching of max and mand






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






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






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






26. Difference between primary and secondary occ trauma






27. Above occlusal plane






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






29. Crowns tipped lingually - roots tipped laterally






30. During protrusive occ - ______ is considered undesirable






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






32. Primary teeth set ___________________ for permanent






33. Anterior; no horizontal overlap






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






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






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






37. #7 - 26 - 27






38. Prognathic profile






39. 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






40. Mesognathic profile






41. Mandibular molars and maxillary molars are even






42. Tooth extracted






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






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






45. Lateral mvmt results in contacct of all posterior teeth






46. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






47. Vertical






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






49. 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






50. Rotated or twisted; rotated mesial or distal
