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 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






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






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






4. #7 - 26 - 27






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






6. Maxillary incisors are are lingual to mandibular incisors






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






8. 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






9. Tooth positioned more lingual






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






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






12. Mandibular molars more distal than maxillary molars






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






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






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






16. Difference between primary and secondary occ trauma






17. Laterally






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






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






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






21. Tooth extracted






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






23. 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






24. Guidance for protrusive occ should be on the






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






26. Relationship of the arches bone to bone;






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






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






29. Prognathic profile; buccal groove of mand. 1st molar-mesial to mb cusp of max. 1st molar; distal of mand. canine mesial to mesial of max canine; tendency toward class III






30. Tongue thrust or thumb sucking can cause






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






32. Both sides






33. Abnormal contacts; occlusal habits - and neuroses






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






35. Mandible moves to the right or left






36. Retrognathic profile






37. Vertical overlapping






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






39. Muscles that work the jaw; may become sore due to occ trauma






40. Vertical






41. When no teeth are contacting on this side






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






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. Cervical 3rd






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






46. Mesially - Labially






47. Occlusal guard =






48. Overlap of anterior teeth






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






50. Measurement of horizontal overlap w/ probe
