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






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






3. After periodontal sugery - mobility will ________






4. Tooth positioned more lingual






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






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






7. Muscles that work the jaw; may become sore due to occ trauma






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






9. What is not affected by occ trauma






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






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






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






13. Introduced the concept of codestruction






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






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






16. Mandibular molars more distal than maxillary molars






17. Vertical overlapping






18. #10 & #23






19. Laterally






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






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






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






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






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






25. Crowns tipped lingually - roots tipped laterally






26. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious






27. Lateral mvmt results in contacct of all posterior teeth






28. Teeth are misaligned when biting together






29. Class III (mal)occlusion of permanent teeth






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






31. Relationship of teeth in which the incisal ridges or buccal cusp ridges of the maxillary anterior teeth extend facially to the incisal ridges/cusps of the mandibular teeth when the teeth are in centric occlusion relationship






32. Measurement of horizontal overlap w/ probe






33. 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






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






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






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






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






38. Difference between primary and secondary occ trauma






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






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






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






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






43. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






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






45. Starts around the mesial of the 1st molar






46. 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






47. Tooth extracted






48. The patient is constantly tightening the lower lip against the lower anterior teeth causing the the mandibular teeth to be pushed back into the mouth by this overdeveloped lower lip






49. Functional occlusion






50. Tooth positioned more facial
