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






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






3. Habitual - acquired - convenience - intercuspal & static






4. 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






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






6. After periodontal sugery - mobility will ________






7. 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






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






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






10. Cervical 3rd






11. Mesognathic profile






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






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






14. Hereditary - Tongue - Intercuspation of teeth - Alignment of previously erupted teeth affects alignment of successive teeth






15. Laterally






16. Maxillary - Mandibular - Facial






17. Abnormal contacts; occlusal habits - and neuroses






18. When no teeth are contacting on this side






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






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






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






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






23. Individual teeth from each arch can be involved in ________________ malocclusion






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






25. Vibrational mvmt of a tooth under occ function






26. Mandibular molars more mesial than maxillary molars (most children)






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






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






29. Crowns tipped lingually - roots tipped laterally






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






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






32. ____ is not a sign of occl trauma






33. Relationship of the arches bone to bone;






34. Posterior; no horizontal overlap






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






36. What is not affected by occ trauma






37. Both sides






38. Tooth positioned more lingual






39. 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






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






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






42. Maxillary anterior teeth stick out labially from tongue thrusting






43. During protrusive occ - ______ is considered undesirable






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






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






46. Occlusal guard =






47. Maximum interlocking of cusp






48. Lateral mvmt results in contacct of all posterior teeth






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






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