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. Maxillary incisors are are lingual to mandibular incisors






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






3. Buck teeth are common and are considered






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






5. Abnormal contacts; occlusal habits - and neuroses






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






7. Below occlusal plane






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






9. Mandible moves to the right or left






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






11. Maxillary anterior teeth stick out labially from tongue thrusting






12. Measurement of horizontal overlap w/ probe






13. After periodontal sugery - mobility will ________






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






15. Relationship of the arches bone to bone;






16. Middle 3rd






17. Mesognathic profile






18. 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






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






20. Habitual - acquired - convenience - intercuspal & static






21. #10 & #23






22. ____ is not a sign of occl trauma

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






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






26. Vertical overlapping

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






31. Need tooth to tooth contact on both working and non working sides to func effectively






32. Reshaping of the occ or incisal surfaces of teeth to create contacts btwn upper and lower dentition






33. During protrusive occ - ______ is considered undesirable






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






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






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






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






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






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






40. Anterior; no horizontal overlap






41. 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
