目的:比较不同系统种植体在口腔正畸中的应用及对种植体周围组织的影响。方法:选取2014年2月至2015年1月在本院接受牙种植术的患者54例,共植入38枚BLB(HA涂层)种植体,45枚ITI(SLA表面)种植体。观察两种系统种植体的应用情况,分别于种植术后3、6、9、12个月检查种植体周围骨吸收量,于基台连接后1、3、6、9个月时采集种植体周围龈沟液(GCF),检测GCF中天冬氨酸转氨酶(AST)水平,并选取种植部位同颌对侧同名天然牙36颗作为对照。结果:BLB、ITI种植体12个月内种植成功率均为100.00%,差异均无统计学意义(P>0.05);术后3、9、12个月时,BLB种植体骨吸收量均明显高于ITI种植体(P<0.05);基台连接后6、9个月时,BLB种植体PICF中AST水平均明显高于ITI种植体和天然牙(P<0.05),而ITI种植体和天然牙间比较,差异均无统计学意义(P>0.05)。结论:BLB、ITI种植体短期内的成功率均较高,其中ITI种植体周围骨组织及软组织稳定性更优。
OBJECTIVE: To compare the application of different system implants in orthodontics and their effects on the tissue around implants. Methods: From February 2014 to January 2015, 54 patients undergoing dental implantation in our hospital were enrolled. A total of 38 BLB (HA coated) implants and 45 ITI (SLA surface) implants were implanted. The application of the two system implants was observed. The bone resorption around the implants were examined at 3, 6, 9 and 12 months after implantation respectively. Implants were collected at 1, 3, 6, and 9 months after abutment connection Gingival crevicular fluid (GCF), GCF aspartate aminotransferase (AST) levels, and select the same site of implantation of the same name with 36 teeth of the same name as the control. Results: The success rates of BLB and ITI implants were all 100.00% within 12 months, with no significant difference (P> 0.05). At 3, 9 and 12 months, the bone resorption of BLB implants were all significantly higher (P <0.05). At 6 and 9 months after abutment abutment, AST levels in PICF of BLB implants were significantly higher than those of ITI implants and natural teeth (P <0.05), while ITI implants and There was no significant difference between the natural teeth (P> 0.05). Conclusion: The success rates of BLB and ITI implants are high in a short period of time, and the stability of bony tissue and soft tissue around ITI implants is better.
