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.
