A dental implant system and method are provided. The dental implant method may include forming a hole in bone of an alveolar of a maxilla, adjacent a sinus cavity. The hole is typically formed so as to leave a bridge portion separating the hole from a bottom surface of a sinus cavity wall. The method may further include separating the bridge portion from the sinus cavity wall, and lifting the bridge portion and the sinus membrane together at least partially into the sinus cavity.
