Abstract

Objective
To compare bone regeneration in critical sized femoral defects in a rabbit model after the application of autogenous graft, biphasic calcium phosphate bone graft and biphasic calcium phosphate bone graft in adjunct to hyaluronic acid gel.
Materials and Methods
6 white New Zealand rabbits about 3-6 months of age were included in this study. Three identical bony defects were created in each femur. Defects are divided into three groups and filled with one of the materials used in this study. Group I: Autogenous bone graft. Group II: Biphasic calcium phosphate (BCP) bone graft and Group III: Hyaluronic acid (HA) gel and BCP. Bone regeneration has been evaluated at 6 and 8 weeks after surgery by means of histological and histomorphometric investigations.
