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






2. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






3. Anterior; no horizontal overlap






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






5. Crowns tipped lingually - roots tipped laterally






6. Starts around the mesial of the 1st molar






7. If the mandible moves to the left - the mvmt is known as a left working movement






8. 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






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






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






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






12. Mandible moves to the right or left






13. Incisal 3rd






14. Mandibular molars and maxillary molars are even






15. Prognathic profile






16. Horizontal distance of anterior teeth in crossbite






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






18. 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






19. Need tooth to tooth contact on both working and non working sides to func effectively






20. Tooth positioned more facial






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






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






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






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






25. Buck teeth are common and are considered






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






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






28. Relationship of the arches bone to bone;






29. Maximum touching of max and mand






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






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






32. #7 - 26 - 27






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






34. Below occlusal plane






35. Guidance for protrusive occ should be on the






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






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






38. Lateral mvmt results in contacct of all posterior teeth






39. Vertical






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






41. During selective grinding - occlusion should be adjusted In what four relationships






42. Mesially - Labially






43. Starts closer to the posterior of the 1st molar






44. Posterior; no horizontal overlap






45. Vibrational mvmt of a tooth under occ function






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






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






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






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






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