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






2. Guidance for protrusive occ should be on the






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






4. Mandibular molars and maxillary molars are even






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






6. 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






7. Cervical 3rd






8. Excessive occ force with adequate bone support =






9. 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






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






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






12. Tooth positioned more facial






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






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






15. Primary teeth set ___________________ for permanent






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






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






18. Above occlusal plane






19. Curved alignment of the occlusal plane when looking from a lateral view(distal to mesial)






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






21. Retrognathic profile; buccal groove of mand 1st molar-distal to mb cusp of max 1st; distal of mand. canine distal to mesial to max caniine - tendency toward class II






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






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






24. Crowns tipped lingually - roots tipped laterally






25. Maxillary incisors are are lingual to mandibular incisors






26. Mandibular molars more mesial than maxillary molars (most children)






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






28. Rotated or twisted; rotated mesial or distal






29. Tongue thrust or thumb sucking can cause






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






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






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






33. Class III (mal)occlusion of permanent teeth






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






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






36. Maxillary - Mandibular - Facial






37. When no teeth are contacting on this side






38. Posterior; no horizontal overlap






39. Radiographically - the PDL space is wider at the coronal third of the root






40. Occlusal guard =






41. Measurement of horizontal overlap w/ probe






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






43. 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






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






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






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






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






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






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






50. II (mal)occlusion
