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






2. ____ is not a sign of occl trauma






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






4. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






5. Tongue thrust or thumb sucking can cause






6. Mandibular molars more distal than maxillary molars






7. Laterally






8. #7 - 26 - 27






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






10. Mobility - migration - pain - premature contact - widening of PDL - parafuntional habits - TMJ problems - all result in _________






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






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






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






14. Maxillary anterior teeth stick out labially from tongue thrusting






15. Usually indicative of moderate to sever perio and secondary occ trauma






16. Both sides






17. 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






18. Middle 3rd






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






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






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






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






23. Later






24. Maxillary incisors are are lingual to mandibular incisors






25. Introduced the concept of codestruction






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






27. Functional occlusion






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






29. Crowns tipped lingually - roots tipped laterally






30. Tooth positioned more lingual






31. Tooth extracted






32. Slight buccal inclination of crown - lingual inclination of root






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






34. Maxillary overlap mandibular; whole arch






35. Habitual - acquired - convenience - intercuspal & static






36. Maxillary - Mandibular - Facial






37. 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






38. Rotated or twisted; rotated mesial or distal






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






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






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






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






43. Primary teeth set ___________________ for permanent






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






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






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






47. Cervical 3rd






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






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






50. During protrusive occ - ______ is considered undesirable
