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. Laterally






2. Associated with performance; all contacts during function of the oral cavity






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






4. 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






5. When no teeth are contacting on this side






6. Excessive occ force with adequate bone support =






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






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

10. Below occlusal plane






11. Primary teeth set ___________________ for permanent






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






13. A tooth that occludes with an opposing tooth before full closure is achieved in centric occlusion






14. 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






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






16. Starts around the mesial of the 1st molar






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






18. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






19. Individual teeth from each arch can be involved in ________________ malocclusion






20. Overlap of anterior teeth






21. Mvmt of the mandible in a direction anterior to centric occ

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






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






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






43. Vibrational mvmt of a tooth under occ function






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






45. Maxillary overlap mandibular; whole arch

48. Prognathic profile






49. Starts closer to premolars






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