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. Maxillary anterior teeth stick out labially from tongue thrusting






2. Widening of the PDL in areas under pressure results due to






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






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






5. Maximum touching of max and mand






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






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






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






9. #7 - 26 - 27






10. Maxillary incisors are are lingual to mandibular incisors






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






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






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






14. Posterior; no horizontal overlap






15. Difference between primary and secondary occ trauma






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






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






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






19. When no teeth are contacting on this side






20. Mandibular molars more distal than maxillary molars






21. Measurement of horizontal overlap w/ probe






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






23. Crowns tipped lingually - roots tipped laterally






24. During protrusive occ - ______ is considered undesirable






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






26. Curve spee & wilson - 3-d - not proven






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






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






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






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






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






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






33. Lateral mvmt results in contacct of all posterior teeth






34. Prognathic profile






35. Middle 3rd






36. Mandibular molars and maxillary molars are even






37. Maximum interlocking of cusp






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






39. Mesially - Labially






40. Abnormal contacts; occlusal habits - and neuroses






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






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






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






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






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






46. Mandible moves to the right or left






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






48. Horizontal






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






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