The bone inferior to the maxilla sinus cavity of a patient is augmented, irrespective of the physical integrity of the Schneiderian membrane, by a resorbable package or vessel that contains granularized bone. The package is matched to be resorbed at about the time the desired bone augmentation is achieved. If an entry is available in the vessel, the ratio of the largest dimension of the vessel entry to the length of the vessel is less than 0.50. The resorbable package may be used with the Caldwell (window) technique or the osteotome technique.
