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. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






2. Maxillary overlap mandibular; whole arch






3. Tongue thrusting; thumb sucking - pacifiers






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






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






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






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






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






9. Mandibular molars more distal than maxillary molars






10. Tongue thrust or thumb sucking can cause






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






12. Class III (mal)occlusion of permanent teeth






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






14. What is not affected by occ trauma






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






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






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






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






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






20. 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






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






22. Buck teeth are common and are considered






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






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






25. After periodontal sugery - mobility will ________






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






27. Posterior; no horizontal overlap






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






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






30. Maxillary anterior teeth stick out labially from tongue thrusting






31. ____ is not a sign of occl trauma






32. Middle 3rd






33. Maxillary incisors are are lingual to mandibular incisors






34. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






35. Tooth positioned more lingual






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






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






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






39. Maxillary - Mandibular - Facial






40. Tooth positioned more facial






41. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






42. Horizontal






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






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






45. Vibrational mvmt of a tooth under occ function






46. Excessive occ force with adequate bone support =






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






48. Prognathic profile






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






50. #7 - 26 - 27
