الزرع الفوري في مناطق الانتان مع استخدام البلازما الغنية بالصفيحات

The purpose of this research is to study the effect of PRP on enhancing and accelerating the osseointegration and reducing the marginal bone resorption around the dental implants in chronic periapical infected sites. The research sample comprised 24 implants which were immediately placed after extraction in infected sites; the sample was divided randomly into 2 groups: (I) received immediate implants without using PRP, and the other (II) received immediate implants with using PRP. Modified plaque index MPI, modified bleeding index MBI, bone density BD, and marginal bone loss MBL Implant survival, were evaluated for both groups. The results of the present study showed that the success rate was 91.6 % in group 1 and 100% in group 2. There was no statistical difference between the test and control regarding MBI, MPI, while there was statistical difference between the test and control regarding MBL during periods of follow up and bone density just after 3 months.
