The aim of the present study is to evaluate the effectiveness of Ditron implants abutment connection (IAC) to sealing the gap between two pieces.
To identify the efficacy of a new IAC, the passage of genetically modified bacteria across IAC was evaluated. A total of five Ditron Implants were used. All implants were immerged in a bacterial culture for forty-eight hours and then bacteria amount was measured inside and outside IAC with Real-time PCR. Bacterial quantification was performed by Real-Time Polymerase Chain Reaction using the absolute quantification with the standard curve method.
In all the tested implants, bacteria were found in the inner side, with a median percentage of 1.35%. The analysis revealed that, in untreated implants, bacteria grew (internally and externally). Moreover, the difference between outer and inner bacteria concentration was statistically significant at each time point.
Ditron Implant IAC (MPI, Ditron Dental, Israel) is efficacy in reducing bacterial leakage.
本研究旨在评估迪特龙种植体基台连接（IAC）在封闭两片之间间隙方面的有效性。
为确定新型IAC的功效，评估了转基因细菌通过IAC的情况。共使用了五颗迪特龙种植体。所有种植体均在细菌培养物中浸泡48小时，然后用实时聚合酶链反应测量IAC内部和外部的细菌数量。细菌定量通过实时聚合酶链反应，采用标准曲线法进行绝对定量。
在所有测试的种植体中，内侧均发现有细菌，中位数百分比为1.35%。分析表明，在未处理的种植体中，细菌生长（内部和外部）。此外，在每个时间点，外部和内部细菌浓度之间的差异具有统计学意义。
迪特龙种植体IAC（MPI，以色列迪特龙牙科公司）在减少细菌渗漏方面有效。
