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






2. 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






3. Starts closer to premolars






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






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






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






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






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






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






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






11. Vertical






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






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






14. Tooth extracted






15. Cervical 3rd






16. Maxillary - Mandibular - Facial






17. Middle 3rd






18. Functional occlusion






19. Mandibular molars more distal than maxillary molars






20. Rotated or twisted; rotated mesial or distal






21. Maxillary incisors are are lingual to mandibular incisors






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






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






24. Relationship of the arches bone to bone;






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






26. Incisal 3rd






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






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






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






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






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






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






33. When no teeth are contacting on this side






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






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






36. #7 - 26 - 27






37. Overlap of anterior teeth






38. Posterior; no horizontal overlap






39. Horizontal






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






41. Mandibular molars and maxillary molars are even






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






43. Prognathic profile






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






45. Abnormal contacts; occlusal habits - and neuroses






46. Introduced the concept of codestruction






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






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






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






50. Teeth that are in func when the mandible moves in lateral or protrusive excursions or mvmts
