Patent ID: 8262665

Claim:
Surgical guide for performing a sinus elevation procedure on a specific patient's maxillary sinus by penetrating a lateral bony wall proximate a maxillary sinus of the patient with a bur, said lateral wall having an external surface, and a varying length, height and depth extending along an X-axis, a Y-axis, and a Z-axis, respectively, said surgical guide comprising: a first curvilinear-shaped subsection for placement adjacent to and in direct and continuous contact with the external surface of said lateral wall of the maxillary sinus, said first curvilinear-shaped subsection having at least one elongated first ledge having a length that extends in a direction along the X-axis of the lateral wall, the first ledge having varying surface contours formed in X-Y and Z-X planes extending along the length to correspond to and align with surface contours formed in X-Y and Z-X planes of the lateral wall at the surgical site, the first ledge being configured to provide continuous contact with the lateral wall along its entire length at a first area of the surgical site; and a second curvilinear-shaped subsection for sequential placement adjacent to and in direct and continuous contact with the external surface of said lateral wall of the maxillary sinus, said second curvilinear-shaped subsection having at least one elongated second ledge having a length that extends in a direction along the X-axis of the lateral wall, the second ledge having varying surface contours formed in X-Y and Z-X planes extending along the length to correspond to and align with surface contours formed in the X-Y and Z-X planes of the lateral wall at the surgical site, the second ledge being configured to provide continuous contact with the lateral wall along its entire length at a second area of the surgical site; wherein the first and second ledges each include variable depths in the Z-X plane and are configured to directly correspond to thickness variations along the Z-X plane of the patient's lateral wall, said first and second ledges permitting movement, guidance and depth control of the bur in three-dimensions.
