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






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






3. Mandible moves to the right or left






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






5. Maxillary incisors are are lingual to mandibular incisors






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






7. Tooth positioned more lingual






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






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






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






11. Vertical






12. Incisal 3rd






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






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






15. Functional occlusion






16. Horizontal distance of anterior teeth in crossbite






17. Later






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






19. Rotated or twisted; rotated mesial or distal






20. Class III (mal)occlusion of permanent teeth






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






22. Cervical 3rd






23. Maxillary anterior teeth stick out labially from tongue thrusting






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






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






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






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






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






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






30. Primary teeth set ___________________ for permanent






31. Horizontal






32. When no teeth are contacting on this side






33. Buck teeth are common and are considered






34. Measurement of horizontal overlap w/ probe






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






36. 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






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






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






39. Tooth positioned more facial






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






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






42. 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






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






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






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






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






47. II (mal)occlusion






48. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






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






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