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






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






4. Starts closer to premolars






5. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






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






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






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






9. II (mal)occlusion






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






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






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






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






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






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






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






17. #10 & #23






18. Mandible moves to the right or left






19. Maximum touching of max and mand






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






21. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






22. Mandibular molars and maxillary molars are even






23. Maxillary - Mandibular - Facial






24. Guidance for protrusive occ should be on the






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






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






27. Middle 3rd






28. Functional occlusion






29. 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






30. Maximum interlocking of cusp






31. Starts around the mesial of the 1st molar






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






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






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






35. Incisal 3rd






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






37. Cervical 3rd






38. Above occlusal plane






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






40. Posterior; no horizontal overlap






41. Maxillary overlap mandibular; whole arch






42. Buck teeth are common and are considered






43. Retrognathic profile






44. Tooth-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






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






46. Mesognathic profile






47. Both sides






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






49. Class III (mal)occlusion of permanent teeth






50. Vertical overlapping
