The Effect of Early Versus Delayed Loading on The Stability of Implants placed by Transalveolar Augmentation Using PRGF In Partially Edentulous Maxilla

INTRODUCTION Two main different protocols are aiming to decrease the time till the loading of the final prosthesis. Immediate loading within the first two weeks after surgery or early loading after at least one month and before six months period (1) Platelets’ from plasma rich in growth factors (PRGF) release various wound healing cytokines and growth factors that have a great role in the process of wound healing, increased vascularity and bone regeneration. (2) This study aimed to compare the effect of early and delayed loading protocols on the stability of implants placed after transalveolar augmentation with PRGF mixed with bone graft in partially edentulous maxilla unilateral free end saddle. Implant stability was measured using Osstell at the time of insertion, loading, three months after loading and six months after loading.
