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. Mand. facial or lingual to max. - unitlateral or bilateral; incorrect horizontal overlap






2. After periodontal sugery - mobility will ________






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






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






5. 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






6. Difference between primary and secondary occ trauma






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






8. Prognathic profile






9. What is not affected by occ trauma






10. Lateral mvmt results in contacct of all posterior teeth






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






12. Abnormal contacts; occlusal habits - and neuroses






13. Habitual - acquired - convenience - intercuspal & static






14. Tongue thrusting; thumb sucking - pacifiers






15. #10 & #23






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






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






18. Mandible moves to the right or left






19. Tongue thrust or thumb sucking can cause






20. Cervical 3rd






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






22. Functional occlusion






23. Permits healing of the attachment apparatus by holding a tooth in a totally fixed position; allows the PDL to become narrower and the mobility to be reduced






24. Crowns tipped lingually - roots tipped laterally






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






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






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






28. Tooth extracted






29. Patients show evidence or signs and syptoms of occ disease






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






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






32. Mand. retruded-one or more max. incisors retruded; max. laterals protruded-max centrals retruded; crowded max anterior teeth; deep overbite






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






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






35. Maxillary anterior teeth stick out labially from tongue thrusting






36. 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






37. Maxillary - Mandibular - Facial






38. Anterior; no horizontal overlap






39. Usually indicative of moderate to sever perio and secondary occ trauma






40. Muscles that work the jaw; may become sore due to occ trauma






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






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






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






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






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






46. Curved alignment of the occlusal plane when looking from a posterior view(right to left)






47. During protrusive occ - ______ is considered undesirable






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






49. Both sides






50. Max canine occludes with mand. canine and mand. 1st premolar.
