Transcript of Growth of the maxilla
- 1. GROWTH OF THE MAXILLA
- 2. 2 types
- 3. 1 Growth at sutures
- 4. Since, the maxillary complex is attached to thecranial base, there is a strong influence of thelatter on the former. Although there is no sharpline of demarcation between the cranium &maxillary growth gradients
- 5. It continues till 10 years ofage thenbecomeslesssignificant. Themaxillaarticulates with the otherbones of the skull by 4 mainsutures:a)Frontomaxillary suture.b)Zygomaticomaxillarysuture.c) Zygomaticotemporal suture.d)Pterygopalatine suture.
- 6. All these sutures are parallel to each other and directed fromupward anteriorly to downward posteriorly. So growth at thesesutures will shift the maxilla forward and downward.
- 7. There areOF
- 8. 1.Downward2.Forward&3.Lateral Forward
- 9. 1.Downward2. Forward 3.Lateraland Forward
- 10. Later the Sutures will turn intofibrous unions Of skull bonesallowing adjustments by appositionand modeling
- 11. 2 Growth by
- 12. Bone remodeling of the palate resulting inits downward displacement
- 13. Enlargement of the maxillary sinus. The sinus expands by bone resorption on the sinus sideand bone deposition on the facial surface of the maxillaryprocess. A process known as pneumotization
- 14. Alveolar process developmentIt will add to the height of the maxilla. Eruption of teeth specially thepermanent set that serves much in this direction, while eruption ofthe upper permanent molars adds to the length of the arch.
