What is a sinus lift procedure?

Timing depends on residual bone height and graft material. When 5 mm or more of native bone remains, many surgeons place implants simultaneously with a crestal lift. For lateral window grafts with under 4 mm residual bone, the healing window is typically 4 to 9 months before implant placement, with xenograft and allograft requiring the longer end of that range and autogenous bone reaching load-bearing density closer to 4 months. The post-graft CBCT confirms density and volume before implant surgery is scheduled.

Schneiderian membrane perforation is the most common intraoperative complication, occurring in 10 to 25 percent of lateral window procedures depending on operator experience and septa anatomy. Small perforations (under 5 mm) are managed with a collagen membrane and the graft proceeds. Larger perforations may require staging the graft to a second appointment. Postoperative sinusitis occurs in roughly 3 to 20 percent of cases and is more common when sinus pathology was present preoperatively, which is why CBCT screening and ENT consultation are part of case planning.

Yes. Dani Dental designs implant surgical guides off the post-graft CBCT for cases where the sinus lift was staged ahead of implant placement, and we coordinate the prosthetic workflow (custom abutments, provisional, final restoration) on a single digital case file. For simultaneous lift-and-place cases, the guide is designed off the preoperative CBCT with the planned augmentation modeled in. Every case ships with the named technician's direct line, and prosthetic delivery is timed to the graft maturation window the surgeon specifies.
