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. Relationship of the teeth in opposite arches; static position






2. Horizontal






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






4. Habitual - acquired - convenience - intercuspal & static






5. Measurement of horizontal overlap w/ probe






6. Laterally






7. Maxillary - Mandibular - Facial






8. Functional occlusion






9. Individual teeth from each arch can be involved in ________________ malocclusion






10. 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






11. Anterior crossbite; max/mand incisors-edge to edge occlusion; crowded mand. incisors






12. Tooth extracted






13. Tooth positioned more facial






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






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






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






17. Prognathic profile






18. 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






19. Lateral mvmt results in contacct of all posterior teeth






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






21. Retrognathic profile






22. Starts around the mesial of the 1st molar






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






24. 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






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






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






27. Guidance for protrusive occ should be on the






28. Maxillary overlap mandibular; whole arch






29. Lateral mvmt results in contact btwn the max and mand canines






30. Occlusal guard =






31. Vertical overlapping






32. Normal contacts between max. and mand. teeth; momentary contacts






33. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






34. Tooth positioned more lingual






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






36. Crowns tipped lingually - roots tipped laterally






37. Incisal 3rd






38. Horizontal distance of anterior teeth in crossbite






39. Maxillary anterior teeth stick out labially from tongue thrusting






40. 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






41. Starts closer to premolars






42. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






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






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






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






46. Tongue thrusting; thumb sucking - pacifiers






47. Buck teeth are common and are considered






48. Relationship of the arches bone to bone;






49. Difference between primary and secondary occ trauma






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