Radiographic and Histomorphometric Assessment for Maxillary Sinus Floor Elevation and Augmentation Using A Mixture of 1:1 Autogenous Bone With Deproteinized Bovine Bone Particulate Versus Deproteinized Bovine Bone Particulate

"Phase 1: Grafting~* after administration of Local anesthesia (articaine hydrochloride 68 mg/1.7 ml~ \+ adrenaline0.017 mg), full-thickness mucoperiosteal flap originating from the mid-crestal area or slightly toward the palate side would be opened.~* lateral window will be created in the maxillary bone to allow for adequate access to the sinus membrane.~* The membrane will be carefully elevated using a sinus elevator.~* bone graft will be placed into the sinus cavity using Autogenous Bone with Deproteinized Bovine Bone Particulate.~* collagen membrane will be secured in place using resorbable sutures or tacks if necessary.~Phase 2 (delayed implant placement and core biopsy harvesting 6 Months Postoperative):~* full thickness mucoperiosteal flap originating from the mid-crestal area or slightly towards palate side would be opened.~* core biopsy would be harvested using trephine burs from the site of implant placement prior to drilling, to be sent to the Lab for Histological assessment."
