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-between canines and laterals - mandibular-between canines and 1st molars






2. Teeth are misaligned when biting together






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






4. Contact between maxillary incisors does not line up with contact of mandibular incisors






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






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






7. Buck teeth are common and are considered






8. Usually indicative of moderate to sever perio and secondary occ trauma






9. Below occlusal plane






10. Maximum touching of max and mand






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






12. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






13. Mandibular molars and maxillary molars are even






14. Introduced the concept of codestruction






15. Laterally






16. 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






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






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






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






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






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






22. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






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






24. ____ is not a sign of occl trauma






25. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






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






27. Difference between primary and secondary occ trauma






28. Spaces between two teeth






29. During protrusive occ - ______ is considered undesirable






30. Habitual - acquired - convenience - intercuspal & static






31. Relationship of the arches bone to bone;






32. Crowns tipped lingually - roots tipped laterally






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. What is not affected by occ trauma






35. II (mal)occlusion






36. Overlap of anterior teeth






37. Maxillary incisors are are lingual to mandibular incisors






38. Curve spee & wilson - 3-d - not proven






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






40. Starts around the mesial of the 1st molar






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






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






43. 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






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






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






46. Tooth positioned more lingual






47. Tooth positioned more facial






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






49. Both sides






50. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip
