Abstract: 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.

Abstract: A drill guide system for use in the installation of dental implants. The guides are configured in the shape of teeth and have drill bushings passing through to guide and position the drill so that the resulting hole will receive an implant that is properly positioned and aligned. The guides are provided in different configurations depending on the number of adjacent implants to be installed and have a depending pin to position the guide in an initial drilled hole. By being configured in the shape of teeth, the dental surgeon is able to position the guide prior to drilling and be able to observe how the resulting work will appear once the actual prosthetics are installed on the implants. The drill bushings not only guide the drill but provide additional patient security since the possibility of slippage or breakage of the drill bit during drilling is substantially reduced.
