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






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






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






4. Mesially - Labially






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






6. Habitual - acquired - convenience - intercuspal & static






7. Difference between primary and secondary occ trauma






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






9. Horizontal distance of anterior teeth in crossbite






10. Mand. retruded-max. incisors protruded; deep overbite; excessive overjet - abnormal muscle function - short mandible - short upper lip






11. #10 & #23






12. After periodontal sugery - mobility will ________






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






14. Anterior; no horizontal overlap






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






16. Maxillary anterior teeth stick out labially from tongue thrusting






17. Rotated or twisted; rotated mesial or distal






18. Measurement of horizontal overlap w/ probe






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






20. II (mal)occlusion






21. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






22. Starts around the mesial of the 1st molar






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






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






25. Middle 3rd






26. Lateral mvmt results in contacct of all posterior teeth






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






28. 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






29. The side to which the mandible moves(chewing side)






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






31. What is not affected by occ trauma






32. When the jaws are closed - the buccal cusps of the mandibular posterior teeth are interlocked between the buccal & lingual cusps of the maxillary teeth






33. Spaces between two teeth






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






35. ____ is not a sign of occl trauma






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






37. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






38. Primary teeth set ___________________ for permanent






39. Maximum touching of max and mand






40. Crowns tipped lingually - roots tipped laterally






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






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






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






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






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






46. 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






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






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






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






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