Differences between Maxillary and Mandibular Incisors – Anatomically

17 main Differences between Maxillary and Mandibular Incisors:

  1. Differences between Maxillary and Mandibular Incisors

    Maxillary Incisors are larger than Mandibular Incisors.

  2. Maxillary incisors have wider Mesio-Distal diameter than Labio-Lingual Diameter.
  3. Mandibular Incisors have wider Labio-lingual Diameter than Mesio-Distal diameter.
  4. Maxillary Incisors have more distinct lingual Anatomy.
  5. Maxillary incisors have lingual pits not found on Mandibular incisors.
  6. Maxilary incisors have rounded roots on cross-section.
  7. All incisors except the Mandibular Central Incisor have Rounded Disto Incisal angle compared to the Mesioincisal Angles – Because Mandibular Central incisor is Symmetrical.
  8. In Mandibular incisors, Incisal edge is lingual to labiolingual midpoint.
  9. Maxillary Incisors Incisal edge is centered Labiolingually
  10. Facial Embrasure is greater than Lingual Embrasure in Mandibular Incisor.
  11. Lingual Embrasure is greater than Facial Embrasure in Maxillary Incisor.
  12. Height of Contour is more incisal on Mandibular Incisor.
  13. Mandibular Incisors Labial surface is straighter and Flatter than Maxillary Incisors.
  14. Smallest Tooth- Mandibular Central Incisor
  15. Bilaterally Symmetric Tooth- Mandibular Central Incisor
  16. Most distinct Lingual Anatomy – Maxillary Lateral Incisor.
  17. Incisal Edge is not Perpendicular to Labio-Lingual Bisecting Linein – Mandibular Lateral Incisor
