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






2. Below occlusal plane






3. Posterior; no horizontal overlap






4. Teeth are misaligned when biting together






5. Horizontal distance of anterior teeth in crossbite






6. Mandibular molars more distal than maxillary molars






7. Horizontal






8. Mesognathic profile






9. Occlusal guard =






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






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






12. Laterally






13. Prognathic profile






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






15. Vibrational mvmt of a tooth under occ function






16. Spaces between two teeth






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






18. 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






19. What is not affected by occ trauma






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






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






22. II (mal)occlusion






23. During protrusive occ - ______ is considered undesirable






24. ____ is not a sign of occl trauma






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






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






27. Maxillary-between canines and laterals - mandibular-between canines and 1st molars






28. Tooth extracted

31. Buck teeth are common and are considered






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






33. Mandibular molars and maxillary molars are even






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

43. The permanent molars erupt posterior to the primary teeth and push them all mesially






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






45. Does not result from brushing at all - but from traumatic lateral forces placed on the teeth as a result of a malocclusion or abnormal tongue activity. Root surface is exposed & can become carious
