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-tooth contacts; tooth-hard objects contacts; tooth-oral tissues contact






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






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






4. Later






5. Guidance for protrusive occ should be on the






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






7. 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






8. Above occlusal plane






9. Functional occlusion

11. When no teeth are contacting on this side






12. Horizontal distance of anterior teeth in crossbite






13. Both sides






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






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






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






17. Tooth positioned more facial






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






19. Tooth extracted






20. #7 - 26 - 27






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






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






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






24. Occlusal guard =






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






26. Abnormal contacts; occlusal habits - and neuroses






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






28. 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






29. Primary teeth set ___________________ for permanent






30. When the jaws are closed - the buccal cusps of the mandibular posterior teeth are interlocked between the buccal & lingual cusps of the maxillary teeth






31. #10 & #23






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






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






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

39. Middle 3rd






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






41. Introduced the concept of codestruction






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






43. Mandibular molars and maxillary molars are even






44. Tongue thrust or thumb sucking can cause

46. The relationship of the teeth in the mandibular arch to those in the maxillary arch as they are brought together






47. What is not affected by occ trauma






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






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






50. 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
