No results posted yet for this study

Summary

two group of patients with atrophied posterior maxilla that need implant/s placement. one group will be subjected to maxillary sinus floor elevation using 1:1 mixture of autogenous bone and deproteinized bovine bone particulate while the other will be subjected to maxillary sinus floor elevation using deproteinized bovine bone particulate alone.

Conditions

  • Maxillary Sinus Lifting

Interventions

PROCEDURE

maxillary sinus floor elevation using Open Maxillary sinus floor elevation and Augmentation using 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.
