Implants, tools, and methods for sinus lift and bone augmentation

An implant apparatus, comprising:

• an anchor having a distal implant end and an opposite proximal end;
• and
• a channel extending through a portion of the anchor, the channel having an outlet opening in the distal implant end, and an inlet opening on a side of the anchor between the distal implant end and the proximal end, wherein the inlet opening, the channel, and the outlet opening are configured to convey fluid therethrough,
• wherein the implant is configured for implantation in, and the anchor is configured for insertion in, a jaw bone such that when fully implanted, the side inlet opening is buried in the jaw bone,
• wherein the anchor is configured to alternatively assume a partially-implanted orientation and a fully-implanted orientation, wherein in the partially implanted orientation the side inlet opening is configured to protrude from the bone to permit access to the channel, and wherein in the fully-implanted orientation the side inlet opening is buried in the bone to block access to the channel,
• wherein the proximal end is configured to permit a prosthesis to be connected thereto when the anchor is in the fully inserted position, and
• further comprising an inlet conduit configured to direct fluid into the channel through the side inlet opening and an integral connection between the anchor and the inlet conduit, the integral connection being configured to be permanently severed during an implantation procedure,
• wherein the integral connection includes a weakened region, such that the inlet conduit is configured to sever from the anchor at the weakened region.

• further comprising:
• an inlet conduit configured to direct fluid into the channel through the side inlet opening and an integral connection between the anchor and the inlet conduit, the integral connection being configured to be permanently severed during an implantation procedure;
• and
• a lever, accessible from the proximal end, for permitting a user to exert force on and sever the integral connection.

An implant method, comprising:

• drilling a hole in a maxillary bone;
• inserting an implant into the hole in a manner forming a substantially liquid tight seal between the implant and the maxillary bone;
• and
• lifting a Schneiderian membrane by introducing fluid through a channel in the implant such that the fluid contacts the Schneiderian membrane and exerts a force thereon, causing a space between the maxillary bone and the Schneiderian membrane,
• wherein the introducing fluid includes introducing fluid through a side inlet opening in the implant, and further comprising subsequently further inserting the implant into the maxillary bone such that the side inlet opening is buried inside the bone.
