Clasification of ma xillary impacted teeth

  1. 1. Clasification of MAXillaryimpacted teeth3rd molars & canines<br /> Done by : Ahmed Al-Asmari @DrAlasmari<br />
  2. 2. Classification of Impacted Third Molar : <br />Removal of an impacted maxillary third molar is difficult because of : <br />insufficient visualization of the area.<br />limited access.<br />maxillary sinus.<br />
  3. 3. Classification: <br />Impaction of the maxillary third molar may be classified as:<br />Mesioangular<br />Distoangular<br />Vertical <br />Horizontal <br />Buccoangular<br />linguoangular<br />Inverted<br />

  5. 5. Cont...<br />Impacted maxillary third molars may also be classified according to the depth of impaction compared to the second molar : <br />Class A: The occlusal surface of the impacted tooth is at approximately the same level as the occlusal surface of the second molar .<br />
  6. 6. Cont...<br />Class B: The occlusal surface of the impacted tooth is at themiddleof the crown of the adjacent second molar . <br />Class C: The occlusal surface of the crown of the impacted tooth is below the cervical line of the adjacent molar or even deeper. <br />

  8. 8. Classification Impacted Canines : <br />Impacted maxillary canines are quite common, and approximately 12%–15% of the population present with impacted canines. <br />They are localized palatally more often than labially.<br />
  9. 9. The impacted canine presents five basic localizations :<br />Palatal localization.<br />Palatal localization of crown and labial localizationofroot.<br />Labial localization of crown and palatal localization of root.<br />Labial localization<br />Ectopic positions<br />
