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






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






3. Vertical






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






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






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






7. Spaces between two teeth






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






9. What is not affected by occ trauma






10. 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






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






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






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






14. 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






15. 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






16. 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






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






18. Occlusal guard =






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






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






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






22. Patient forces teeth together in centric occlusion on one side to get a more functional bite and has a crossbite on the other side(the midline of the maxillary anterior teeth does not line up with the midlineof the mandible






23. Tongue thrust or thumb sucking can cause






24. Lateral mvmt results in contacct of all posterior teeth






25. 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






26. Overlap of anterior teeth






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






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






29. ____ is not a sign of occl trauma






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






31. Any occl that produces forces that directly or indirectly cause injury to the attachment apparatus






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






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






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






35. Individual teeth from each arch can be involved in ________________ malocclusion






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






37. Severe ging inflammation extending into CT attachment - loss of supporting alveolar bone - pregnancy - ortho mvmt - and surgical therapy - may all cause ______






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






39. Mandibular molars more distal than maxillary molars






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






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






42. Tooth positioned more lingual






43. #7 - 26 - 27






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






45. 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






46. Later






47. Measurement of horizontal overlap w/ probe






48. Habitual - acquired - convenience - intercuspal & static






49. II (mal)occlusion






50. Rotated or twisted; rotated mesial or distal
