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






2. Tongue thrusting; thumb sucking - pacifiers






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






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






5. Vertical overlapping






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






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






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






9. Vibrational mvmt of a tooth under occ function






10. Tooth positioned more lingual






11. Teeth are misaligned when biting together






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






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






14. 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






15. 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






16. Maximum interlocking of cusp






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






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






19. When no teeth are contacting on this side






20. Curve of the occlusal plane; from anterior to posterior - increases with age






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






22. Cervical 3rd






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






24. Mesially - Labially






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






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






27. Maxillary incisors are are lingual to mandibular incisors






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






29. #10 & #23






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






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






32. After periodontal sugery - mobility will ________






33. Excessive occ force with adequate bone support =






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






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






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






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






38. Abnormal contacts; occlusal habits - and neuroses






39. Vertical






40. Difference between primary and secondary occ trauma






41. Occlusal guard =






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






43. Horizontal






44. 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






45. Cusps of maxillary teeth directly over cusps of mandibular teeth






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






47. Above occlusal plane






48. Incisal 3rd






49. Below occlusal plane






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