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






2. Tongue thrusting; thumb sucking - pacifiers






3. During selective grinding - occlusion should be adjusted In what four relationships






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






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






6. 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






7. Posterior; no horizontal overlap






8. Tooth extracted






9. Anterior teeth do not occlude - or remain open - while posterior teeth may have a normal occlusion






10. Class III (mal)occlusion of permanent teeth






11. Prognathic profile






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






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






14. Maxillary anterior teeth stick out labially from tongue thrusting






15. Introduced the concept of codestruction






16. II (mal)occlusion






17. Overlap of anterior teeth






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






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






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






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






22. Tooth positioned more lingual






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






24. Abnormal contacts; occlusal habits - and neuroses






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






26. Horizontal distance of anterior teeth in crossbite






27. Maximum touching of max and mand






28. 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






29. Tongue thrust or thumb sucking can cause






30. Measurement of horizontal overlap w/ probe






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






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






33. Can be caused by forces of malocclusion - teeth can become loose - periodontal disease may develop(alveolar bone loss)






34. Occlusal guard =






35. Curve spee & wilson - 3-d - not proven






36. Selective grinding should always be completed after ______ has been controlled






37. Teeth are misaligned when biting together






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






39. Any deviation from the ideal or normal occl. includes crowding - malpositioned or tipped teeth






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






41. Functional occlusion






42. Vertical overlapping






43. Above occlusal plane






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






45. Cusps of maxillary teeth directly over cusps of mandibular teeth






46. Laterally






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






48. During protrusive occ - ______ is considered undesirable






49. Spaces between two teeth






50. ____ is not a sign of occl trauma
