In this study the role of rh-PDGF along with a bioresorbable carrier beta-TCP and resorbable barrier membrane (polyglycolide, polylactide and d,l-lactide/glycolide copolymer)were used in the management of peri-implant defects and also determine the value of resorbable barrier membrane to improve the efficacy of the procedure . It is very helpful to regenerate the deficient alveolar bone specially in fully/partially edentulous patients for housing the dental Implant.
