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






2. Class III (mal)occlusion of permanent teeth






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






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






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






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






7. Excessive occ force with adequate bone support =






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






9. 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






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






11. Above occlusal plane






12. 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






13. Spaces between two teeth






14. Posterior; no horizontal overlap






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






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






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






18. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






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






20. 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






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






22. #7 - 26 - 27






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






24. Vibrational mvmt of a tooth under occ function






25. During selective grinding - occlusion should be adjusted In what four relationships






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






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






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






29. Measurement of horizontal overlap w/ probe






30. Starts closer to premolars






31. Buck teeth are common and are considered






32. Rotated or twisted; rotated mesial or distal






33. Vertical overlapping






34. Both sides






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






36. Survival of the dentition despite its deviation from a preconceived hypothetical normal






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






38. Tongue thrusting; thumb sucking - pacifiers






39. Retrognathic profile






40. Occlusal guard =






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






42. Starts around the mesial of the 1st molar






43. 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






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






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






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






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






48. Curved alignment of the occlusal plane when looking from a lateral view(distal to mesial)






49. Tooth positioned more lingual






50. Starts closer to the posterior of the 1st molar
