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. Tooth extracted






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






3. Mandibular molars and maxillary molars are even






4. Overlap of anterior teeth






5. Tooth positioned more facial






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






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






8. ____ is not a sign of occl trauma






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






10. Maxillary anterior teeth stick out labially from tongue thrusting






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






12. Measurement of horizontal overlap w/ probe






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






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






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






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






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






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






19. Excessive occ force with adequate bone support =






20. The tooth has insufficient bone support and normal chewing and swallowing forces are excessive - causing injury to the attachment appartatus






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






22. Starts around the mesial of the 1st molar






23. Tooth positioned more lingual






24. Posterior; no horizontal overlap






25. Teeth are misaligned when biting together






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






27. Injury to the attachment apparatus (bone - PDL - and cementum) as a consequence of normal or excessive occ forces






28. During protrusive occ - ______ is considered undesirable






29. Transverse occlusal curvature; posterior teeth; medio-lateral postion (r-l)






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






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






32. Vertical






33. Both sides






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






35. Occlusal guard =






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. Relationship of the arches bone to bone;






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






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






40. The side to which the mandible moves(chewing side)






41. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






43. Incisal 3rd






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






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






46. 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






47. Retrognathic profile






48. Contact between maxillary incisors does not line up with contact of mandibular incisors






49. 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






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