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






2. 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






3. Maxillary anterior teeth stick out labially from tongue thrusting






4. Maximum interlocking of cusp






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






6. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






7. Incisal 3rd






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






9. Tooth positioned more lingual






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






11. What is not affected by occ trauma






12. Mandible moves to the right or left






13. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






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






15. 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






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






17. The way you normally bite your teeth together when not chewing






18. 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






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






20. Measurement of horizontal overlap w/ probe






21. Overlap of anterior teeth






22. 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






23. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






24. Class III (mal)occlusion of permanent teeth






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






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






27. Tooth positioned more facial






28. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






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






30. Habitual - acquired - convenience - intercuspal & static






31. Posterior; no horizontal overlap






32. Tooth extracted






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






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






35. After periodontal sugery - mobility will ________






36. 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






37. Teeth are misaligned when biting together






38. Lateral mvmt results in contacct of all posterior teeth






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






40. Maxillary overlap mandibular; whole arch






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






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






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






44. Prognathic profile






45. During protrusive occ - ______ is considered undesirable






46. Buck teeth are common and are considered






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






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






49. Curve spee & wilson - 3-d - not proven






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