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 protrusive occ - ______ is considered undesirable






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






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






4. Prognathic profile






5. Deciduous molars and canines are wider than permanent premolars and canines; space saved during mesial drift of permanent molars






6. After periodontal sugery - mobility will ________






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






8. Lateral mvmt results in contacct of all posterior teeth






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






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






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






12. Laterally






13. Overlap of anterior teeth






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






15. Anterior or posterior; bilateral or unitlateral - anterior more common






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






17. 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






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






19. #7 - 26 - 27

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






22. Introduced the concept of codestruction






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






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






25. 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






26. Occlusal forces will accelerate the rate of perio destruction and result in CT attachment loss in the presence of preexisting inflammation






27. Both sides






28. Excessive occ force with adequate bone support =






29. Widening of the PDL in areas under pressure results due to






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