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






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






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






4. Most common cause is when the maxilla does not grow in proportion to the mandible






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






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






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






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






9. Starts closer to premolars






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






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






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






13. Mandible moves to the right or left






14. Below occlusal plane






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






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






17. Starts around the mesial of the 1st molar






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






19. Horizontal






20. During protrusive occ - ______ is considered undesirable






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






22. Prognathic profile






23. Above occlusal plane






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






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






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






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






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






29. Guidance for protrusive occ should be on the






30. Vertical

32. Functional occlusion






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






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






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






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






37. 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






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






39. Tongue thrust or thumb sucking can cause






40. Mesognathic profile






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






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






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






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