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.
