Maxilla is a membranous bone and development/growth of maxilla is completed early & when compared to mandible. Maxilla (width) follows closely neural growth curve more than the general growth curve in scammon’s curve, Maxilla cannot be considered as separate bone it has to be nasomaxillary complex because of close association or attachment of maxilla to cranial base. Displacement, Growth at sutures, Surface remodelling, The mandible,at Birth is small, with short ramus,large gonial angle, and flat, mandibular fossa with no articular eminence.The condyles are at the level of the occlusal plane. It appears as if mandibular growth is forward and downwards, and as such one could suppose that the mandible enlarges by growth at the anter, ior end. Limited growth takes place at the symphysis menti until fusion occurs. At the condylar cartilages, Posterior border of ramus, Alveolar Ridges, Growth Progresses,bone from one leve lin the condylepper ramus region, getsincorporatedintothenextlevellowerdown. Insequence:, Condylar head parts incorporated into new upper Condylar neck, Upper parts of the neck undergo remodelling conversion into the new lower parts The lower portions receive direct remodelling changes into the ramus proper.
