Osseointegration of chemically modified sandblasted and acid-etched titanium implant surface in diabetic rats: a histological and scanning electron microscopy study.

INTRODUCTION The aim of this study is to assess the osseointegration of different dental implants surfaces in diabetic rats. MATERIALS AND METHODS In this study, were used 56 male Wistar rats, average weight of 300-350 g. Diabetes was induced by a single intraperitoneal injection of Streptozotocin. The glucose levels and weight of rats were periodically evaluated. After the diabetes mellitus is confirmed, the sandblasted, large-grit, acid-etched (SLA) and SLActive endosseous dental implants (TAG dental implants, TAG Medical, Israel), made of titanium alloy, Ti-6Al-4V, 1 mm diameter and 3 mm in length were inserted in the distal metaphysis of the left femur. RESULTS Diabetic rats have naturally lower number of bone cells and bone-implant contact (BIC%) than healthy rats when using the SLA implant, but when using SLActive implant, diabetic and healthy rats have the same numbers. CONCLUSIONS The use of the SLActive surface resulted in positive effects in healthy and especially in diabetic animals, which demonstrate that could improve the osseointegration progress in humans with diabetes.
