GUIDED SINUS LIFT

摘要

A method and apparatus are herein provided, the method including: receiving a three dimensional virtual model of a maxillary alveolar bone of a patient, and a digital dental implant plan that defines a planned dental implant site of the maxillary bone; receiving a set of values consisting of predefined distances; creating a virtual model of a surgical guide stent for placement against an occlusal surface, wherein the virtual model of the surgical guide stent defines: a hole through the surgical guide stent at a site corresponding to the planned dental implant site defined in the digital dental implant plan, and an inferior surface surrounding the hole; and outputting the virtual model of the surgical guide stent in association with the one of the predefined distances.

1. A method comprising:
receiving (a) a three-dimensional virtual model of at least a maxillary alveolar bone of a patient, and (b) at least one digital dental implant plan that defines a planned dental implant site of the maxillary bone; receiving a set of values consisting of between two and eight predefined distances; creating a virtual model of a surgical guide stent for placement against an occlusal surface selected from the group consisting of: an occlusal surface of the maxillary bone of the patient, an occlusal surface of gingiva covering the maxillary bone, and an occlusal surface of teeth near the planned dental implant site, wherein the virtual model of the surgical guide stent defines: a hole through the surgical guide stent at a site corresponding to the planned dental implant site defined in the digital dental implant plan, and an inferior surface surrounding the hole, such that one of the predefined distances of the set equals a sum of (a) a modeled distance between the inferior surface and a superior surface of the maxillary bone and (b) an over-advancement depth equal to between 0.1 and 5mm; and outputting the virtual model of the surgical guide stent in association with the one of the predefined distances.
