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






3. Introduced the concept of codestruction






4. Mandible moves to the right or left






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






6. Primary teeth set ___________________ for permanent






7. II (mal)occlusion






8. 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






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






10. Mandibular molars and maxillary molars are even






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






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






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






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






15. Maxillary anterior teeth stick out labially from tongue thrusting






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






17. Lateral mvmt results in contact btwn the max and mand canines






18. 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






19. Mandibular molars more distal than maxillary molars






20. Posterior; no horizontal overlap






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






22. Buck teeth are common and are considered






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






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






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






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






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






28. Anterior; no horizontal overlap






29. High restoration - parafunctional habits - malpositioned tooth - periapical abcess - physical 'blow' - removable partial - ortho mvmt






30. Maxillary - Mandibular - Facial






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






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






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






34. Cervical 3rd






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






36. Horizontal






37. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






38. Difference between primary and secondary occ trauma






39. Maximum touching of max and mand






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






41. Selective grinding should always be completed after ______ has been controlled






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






43. Later






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






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






46. Vibrational mvmt of a tooth under occ function






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






48. Excessive deposition of cementum around the apex - due to excessive occlusal forces






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






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