I have a patient with 3mm of residual bone in the maxilla under the maxillary sinus. I want to place a 4x9mm Morse taper implant after sinus lift and bone graft. I was thinking of using OsteoVation (OsteoMed), a calcium phosphate bone cement for the graft. Has anybody used this for bone augmentation to the sinus? How long should I wait to place the implant after grafting?
