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. Malocclusion cause excessive incisal or occlusal wear(attrition); teeth continue to erupt in order to occlude with teeth in the opposite arch & roots become exposed






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






3. Maxillary incisors are are lingual to mandibular incisors






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






5. Habitual - acquired - convenience - intercuspal & static






6. Vibrational mvmt of a tooth under occ function






7. Incisal 3rd






8. 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






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






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






11. Mandible moves to the right or left






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






13. Tooth positioned more lingual






14. Starts around the mesial of the 1st molar






15. 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






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






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






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






19. Occlusal guard =






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






21. Crowns tipped lingually - roots tipped laterally






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






23. Relationship of the arches bone to bone;






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






25. Class III (mal)occlusion of permanent teeth






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






27. Both sides






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






29. Tooth extracted






30. 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






31. Mesognathic profile






32. Mandibular molars more distal than maxillary molars






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






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






35. During protrusive occ - ______ is considered undesirable






36. Retrognathic profile -buccal groove of mand. 1st molar-distal to mb cusp of 1st max.molar -distal of mand canine distal to mesial of max canine - tendency towards class II






37. Later






38. Mandibular molars and maxillary molars are even






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






40. Starts closer to premolars






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






42. Tongue thrust or thumb sucking can cause






43. Mesially - Labially






44. Maxillary - Mandibular - Facial






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






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






47. II (mal)occlusion






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






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






50. Introduced the concept of codestruction
