Evaluation of the Outcome of Osseodensification by Using Densah Burs and Bone Expanders in Cases of Posterior Mandibular Bone Atrophy A Randomized Controlled Study

INTERVENTION: Bone expander Densah Burs CONDITION: ; Oral Health Oral Health PRIMARY OUTCOME: CBCT was done immediately after placing the implant. Using Scanora 3Dx scanner CBCT machine. And for measurements were using OnDemand3D application immediately following implant placement for measuring the bone density around the implant. CBCT was done immediately after placing the implant. Using Scanora 3Dx scanner CBCT machine. And for measurements were using OnDemand3D application immediately following implant placement for measuring the buccal bone thickness to the implant. CBCT was done immediately after placing the implant. Using Scanora 3Dx scanner CBCT machine. And for measurements were using OnDemand3D application immediately following implant placement for measuring the crestal height to the implant. initial stability were assessed immediately after implant placement with an Osstell® Mentor magnetic resonance device. SECONDARY OUTCOME: CBCT was done after 4 months. Using the Scanora 3D Xscanner CBCT machine. And for measurements, we were using the OnDemand3D application for measuring the bone density around the implant. CBCT was done after 4 months. Using the Scanora 3D Xscanner CBCT machine. And for measurements, we were using the OnDemand3D application for measuring the buccal bone thickness to the implant. CBCT was done after 4 months. Using the Scanora 3D Xscanner CBCT machine. And for measurements, we were using the OnDemand3D application for measuring the crestal height to the implant. Stability was assessed after 4 months of implant placement with an Osstell® Mentor magnetic resonance device.
