What is the recommended remaining bone height for performing an indirect sinus lift?

• A. 2mm
• B. 4mm
• C. 5mm
• D. 6mm

Answer: (C)

In the context of performing an indirect sinus lift, the precise remaining bone height is crucial for successful surgical outcomes. The recommended minimum remaining bone height before considering an indirect sinus lift is typically around 5mm. This height is essential because it provides adequate support for the placement of the sinus lift instruments and materials, such as grafting agents, while ensuring that the sinus membrane is not inadvertently perforated during the procedure. When the bone height is too low, there is an increased risk of complications, including failure to adequately elevate the sinus membrane or failure of the graft due to insufficient space. A minimum of 5mm allows for a safe and effective lift while creating enough vertical space to accommodate the graft material that promotes bone regeneration and stabilization for future implant placement. Thus, a remaining bone height of 5mm is the threshold that maximizes chances of a successful procedure while minimizing potential complications.
