Graftless lateral sinus floor elevation utilizing a new implant design
In this video, a new implant design was used with maxillary sinus floor elevation. The design allowed the implant threads to ‘rescue’ chips of bone from the osteotomy walls at the moment of insertion. After the Schneiderian membrane is lifted, these bone chips are pushed further into the sinus while the implant is inserted. It is hypothesised that the bone debris created by the drilling can facilitate new bone formation in the defect. Some studies on sinus floor elevation have come to this same conclusion (Dhore et al. 2008; Tabassum et al. 2009; Jungner et al. 2014).
“It is hypothesised that the bone debris created by drilling can facilitate new bone formation in the defect”
The video showed footage from the endoscopy, where it was visible how bone particles from the osteotomy attached to the implant surface and climbed along with it at the time of insertion into the sinus cavity. After the implant was placed (without grafting) the bone of the lateral bony window was replaced and ‘fixed’ with cyanoacrylate in the same position as it was before. 12-month post-op CBCT images showed bone formation around the implant, mostly around the middle third, with less around the apex.
