Sinus Lift Grafting Surgery

Sinus lift/ elevation for implant placement

One of the main criteria of implant placement for replacement of the upper back teeth is to prevent damage to the sinus floor. In situations that the floor of the sinus is too low, the sinus floor must be elevated and the space must be augmented with bone graft materials to create enough vertical space between the jaw bone and the floor of the sinus for dental implant placement. The bone used in a sinus lift may derived from your own body (autogenous bone), from animal like pig (xenograft), or from a cadaver (allograft bone).

This procedure is called sinus lift/elevation. A sinus lift surgery usually should be performed by an expert specialist such as a periodontist or an oral surgeon. The healing period for conventional sinus lift procedure is at around 7-9 months and additional 4 months should be considered for integration of the implant too.
Perforation of the sinus membrane is one of the main complications. If this happens during the procedure, the surgical site must be repaired and another attempt for sinus elevation must be considered after healing of the membrane which usually takes a few months.
  • Infection is a risk of any surgical procedure. However, this rarely occurs after sinus lifts.
  • Failure in integration of grafted bone, in the situation, if there no enough live bone is available for implant placement, the sinus lift procedure and bone graft should be repeated.
  • What are the risks with this procedure?
