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. Measurement of horizontal overlap w/ probe






2. Maxillary anterior teeth stick out labially from tongue thrusting






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






4. 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






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






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






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






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






9. #7 - 26 - 27






10. Excessive occ force with adequate bone support =






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






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






13. Later






14. Prognathic profile






15. Retrognathic profile






16. Mandibular molars and maxillary molars are even






17. Functional occlusion






18. Tooth positioned more lingual






19. Mesognathic profile






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






21. Horizontal






22. Posterior; no horizontal overlap






23. Maxillary overlap mandibular; whole arch






24. Mandible moves to the right or left






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






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






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






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






29. Spaces between two teeth






30. Maximum touching of max and mand






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






32. 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






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






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






35. Lateral mvmt results in contacct of all posterior teeth






36. Relationship of the arches bone to bone;






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






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






39. Starts around the mesial of the 1st molar






40. Vibrational mvmt of a tooth under occ function






41. Overlap of anterior teeth






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






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






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






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






46. During protrusive occ - ______ is considered undesirable






47. 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






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






49. Rotated or twisted; rotated mesial or distal






50. 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
