摘要: 目的:研究雷奈酸锶治疗对骨质疏松时种植体骨结合的影响。方法:36只雌性SD大鼠随机分成骨质疏松组(A组,行双侧卵巢手术)、雷奈酸锶低剂量治疗组(B组,同A组手术)、 雷奈酸锶高剂量治疗组(C组,同A组手术)(n=12),骨质疏松模型造模成功后,在SD大鼠右侧胫骨近中干骺端植入羟基磷灰石涂层种植体,同时B组给予雷奈酸锶450 mg·kg-1·d-1口服,C组给予雷奈酸锶900 mg·kg-1·d-1口服,种植术后12周,处死动物,标本制作不脱钙硬组织标本,行形态学、显微CT观察及骨计量学检测。 结果:种植术后12周,B、C组种植体周骨密度、种植体骨结合率、新生骨量均显著高于A组(P<0.01),但C组与B组比较,各项指标差异不显著。结论:雷奈酸锶应用可拮抗骨质疏松的负面影响,促进种植体愈合,使种植体骨结合率增加。

Abstract: Objective: To investigate the effect of strontium ranelate on osseointergration in osteoporotic rats. Method: Thirty-six female rats were randomly divided into three groups: ovariectomization group(A=12), strontium ranelate lower dose treatment group(B=12) and strontium ranelate high dose treatment group(C=12). Animals all received bilateral ovariectomy. After the success of the osteoporosis model building, HA coated titanium implants were inserted into proximal metaphyses of tibiae, meanwhile, the animals of group B and C were received oral medication strontium ranelate(B:450mg·kg-1·d-1 C:900mg·kg-1·d-1), Twelve weeks after surgery, animals were killed and undecalcified sections were prepared and examined histologically, micro-CT examnation and histomorphometrically. Results: 12 weeks after implantation surgery, BMD, IBCR and NBV in group B and C were significantly higher then those in group A(P<0.01). Conclusion: Strontium ranelate may resist the negative influence of osteoporosis and promote osseointagration of implant.
