66 year old healthy male wishes to commence tx on the UL quadrant. Large sinus with horizontal bone loss. Considered sinus lift alone however this will lead to long lever arms and high torque on the implants. Would like to augment bone vertically. I am considering use of BMP. Would you do the same? If so How much? Would you also graft the sinus and if so Conventionally or with BMP? I have recommended the removal of implant #15(no bone not mine). Tooth #12 is fractured will be removed. Implants placed eventually in #12 and #14 positions to provide abutments for a 3 unit fixed partial denture. The goal is to provide first molar occlusion as #18 will be removed due to 9mm pockets. If BMP is used would you also use ti-Mesh or tent screws? Thanks for the help!!!!
