ABSTRACT:
A dental implant system and method are provided. The dental implant system typically includes a boring device for boring a hole in an alveolar bone and leaving a bridge portion separating the hole from the maxillary sinus cavity. The system may also include a scoring device for scoring the bridge portion, and a lifting device for breaking the bridge portion along the score, and lifting the freed bridge portion a first predetermined distance. The system may further include a membrane separation elevator for separating the sinus membrane from the sinus cavity wall. The system may also include a second lifting device configured to contact the freed bridge portion to further raise the freed bridge portion and sinus membrane together to a second predetermined penetration distance into the sinus cavity.
