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






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






3. Mandible moves to the right or left






4. Lateral mvmt results in contacct of all posterior teeth






5. Starts around the mesial of the 1st molar






6. Introduced the concept of codestruction






7. Horizontal distance of anterior teeth in crossbite






8. Prognathic profile






9. #10 & #23






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






11. Above occlusal plane






12. Teeth are misaligned when biting together






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






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






15. Both sides






16. Maximal intercuspation or contact of the max and mand teeth






17. Primary teeth set ___________________ for permanent






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






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






20. Mesially - Labially






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






22. When no teeth are contacting on this side






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






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






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






26. Overlap of anterior teeth






27. Below occlusal plane






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






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






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






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






32. 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






33. Tooth positioned more facial






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






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






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






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






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






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






40. Maximum interlocking of cusp






41. Congenitally missing teeth - Impacted teeth & size and shape of muscle and bone






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






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






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






45. ____ is not a sign of occl trauma






46. 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






47. Overclosure of the anterior teeth can cause trauma to the gingiva of the max teeth






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






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






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