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. Mesognathic profile






3. Maximum interlocking of cusp






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






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

7. After periodontal sugery - mobility will ________






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






9. Tooth positioned more lingual






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






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






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






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






14. Tooth extracted






15. Max. incisors lingual to mand. incisors; incorrect horizontal overlap






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






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






18. During a left working movement - the right side is known as the






19. Tongue thrust or thumb sucking can cause






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






21. Mesially - Labially






22. Mandible moves to the right or left






23. Vertical overlapping






24. Incisal 3rd






25. 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






26. Relationship of the teeth in opposite arches; static position






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






28. Can affect the TMJ - muscles of mastication - pulp and integrity of restorations






29. Position of the mandible relative to the maxilla during swallowing and other times when the jaw muscles contract






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






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






32. 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






33. Curve of the occlusal plane; from anterior to posterior - increases with age






34. Vertical






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






36. Horizontal distance of anterior teeth in crossbite

42. Functional occlusion






43. Tongue thrusting; thumb sucking - pacifiers






44. 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






45. Maxillary anterior teeth stick out labially from tongue thrusting
