【摘要】：目的研究氧化锆和纯钛基底冠材料及饰瓷烧结对种植全冠内部和边缘适合性的影响。方法制作计算机辅助设计/计算机辅助制作(CAD/CAM)氧化锆烤瓷种植全冠(A组)和纯钛烤瓷种植全冠(B组)各8个(n=8)。分别用硅橡胶轻体复制饰瓷烧结前基底冠和饰瓷烧结后全冠的内部和边缘间隙,采用Micro-CT扫描硅橡胶,建立三维图像,测量冠边缘垂直间隙(MG)、冠边缘水平间隙(HMD)和冠内部轴面中点间隙(AW)。采用SPSS17.0软件对测量结果进行统计学分析。结果饰瓷烧结前,A组基底冠MG、HMD和AW均大于B组(P0.05)。饰瓷烧结后,A组全冠MG小于B组(P0.05),两组的HMD和AW均无统计学差异(P0.05)。饰瓷烧结使A组MG减小(P0.05),使B组MG、HMD和AW均增大(P0.05),而A组HMD和AW烧结前和烧结后的差异无统计学意义(P0.05)。结论氧化锆烤瓷种植全冠边缘适合性优于纯钛烤瓷种植全冠;饰瓷烧结对氧化锆和纯钛烤瓷种植全冠适合性均会产生影响。
[Abstract]:Objective to study the effect of sintered zirconia and pure titanium substrate and porcelain on the interior and edge suitability of implant crown. Methods computer aided design (CAD / CAM) zirconia ceramic implants (group A) and pure titanium fused porcelain (group B) (n = 8) were made. The inner and edge gaps of the base crown and the whole crown after sintering were reproduced by using silicone rubber light body, respectively. The Micro-CT scanning silicone rubber was used to establish the 3D image. The vertical gap of the crown edge, the horizontal gap of the crown edge and the gap between the central point of the inner axial plane of the crown were measured. The measurement results were statistically analyzed by SPSS17.0 software. Results the HMD and AW of group A were higher than that of group B before sintering. After sintering, the full crown MG of group A was lower than that of group B (P 0.05). There was no significant difference in HMD and AW between the two groups (P 0.05). Sintered porcelain made MG in group A decrease P0.05U, HMD and AW increased in group B, but there was no significant difference between group A HMD and AW before and after sintering. Conclusion the edge suitability of Zirconia ceramic implant crown is better than that of pure titanium fused porcelain crown, and the effect of ceramic sintering on the fit of zirconia and titanium fused porcelain implant crown is significant.
