摘要：
Tooling and methodologies for separation and dissection of the subantral membrane from the floor of the maxillary sinus, and for packing bone and bone substitutes under the subantral membrane. The tooling and associated methodology employ a handle and one or more support structures extending therefrom. A thin member extends from the distal end of the support structure(s). The thin member has a first peripheral region disposed opposite a second peripheral region. The first peripheral region is joined to or integrally formed with the distal end of the support structure(s). The second peripheral region defines a thin blade-like section for dissecting the subantral membrane from the floor of the maxillary sinus. In the preferred embodiment, the blade-like section is angled downward away from the distal support structure, which aids in positioning the blade-like section on the floor of the maxillary sinus.
