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. Maxillary - Mandibular - Facial






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






3. Starts around the mesial of the 1st molar






4. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






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






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






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






8. #10 & #23






9. Mvmt of the mandible in a direction anterior to centric occ






10. Mesially - Labially






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






12. Tongue thrust or thumb sucking can cause






13. II (mal)occlusion






14. Tooth positioned more facial






15. Buck teeth are common and are considered






16. Abnormal contacts; occlusal habits - and neuroses






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






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






19. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






21. During protrusive occ - ______ is considered undesirable






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






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






24. Primary teeth set ___________________ for permanent






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






26. After periodontal sugery - mobility will ________






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






28. 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






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






30. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






31. Vertical






32. Vertical overlapping






33. 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






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






35. Both sides






36. Maxillary anterior teeth stick out labially from tongue thrusting






37. Crowns tipped lingually - roots tipped laterally






38. Anterior; no horizontal overlap






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






40. Curve of the occlusal plane; from anterior to posterior - increases with age






41. Lateral mvmt results in contacct of all posterior teeth






42. What is not affected by occ trauma






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






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






45. Prognathic profile






46. Tongue thrusting; thumb sucking - pacifiers






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






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






49. 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






50. Posterior; no horizontal overlap
