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






3. Above occlusal plane






4. Teeth are misaligned when biting together






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






6. Horizontal






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






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






9. Most retruded position of the mandible in relation to the maxilla From which lateral mvmts of the jaw can be made






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






11. Starts closer to premolars






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






13. When one tooth hits before all others when closing teeth together(may cause TMJ problems)






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






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






16. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






17. II (mal)occlusion






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






19. Measurement of horizontal overlap w/ probe






20. Horizontal distance of anterior teeth in crossbite






21. Abnormal contacts; occlusal habits - and neuroses






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






23. Excessive occ force with adequate bone support =






24. #7 - 26 - 27






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






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






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






28. Tooth positioned more lingual






29. Maxillary incisors are are lingual to mandibular incisors






30. Below occlusal plane






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






32. Transverse occlusal curvature; posterior teeth; medio-lateral postion (r-l)






33. A continuation of the spee of to extend through the condyle






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






35. Crowns tipped lingually - roots tipped laterally






36. Mesognathic profile






37. Mesially - Labially

39. Posterior; no horizontal overlap






40. During protrusive occ - ______ is considered undesirable






41. Maximum touching of max and mand






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






43. Maximum interlocking of cusp






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






45. Relationship of the arches bone to bone;






46. Vertical






47. Retrognathic profile
