Influence of direct laser metal sintering implants on the early stages of osseointegration in diabetic mini-pigs.
摘要
Abstract
Objective The diabetic pig model was established by intravenous injection of streptozocin in order to investigate whether direct laser metal sintering (DLMS)could improve osseointegration in diabetic animal models.Methods A diabetes model in mini-pigs was established by intravenous injection of streptozotocin (STZ)(150 mg/kg),and a total of 36 implants were inserted into the nandibular region.Micro-computed tomography (micro-CT)and histologic evaluations were performed three and six months after implantation.Results The blood glucose level remained at high level (≥ 10 mmol/L) after the induction of diabetes,reaching the diabetic level (≥ 7 mmol/L).Obvious improvement in osseointegration was observed in the micro-CT and Van Gieson (VG)staining analyses of DLMS implants compared with MAO at three months (P < 0.05),although this difference disappeared by six months (P > 0.05).Conclusion The rough surface of DLMS implants can accelerate the progress of osseointegration.关键词
