【摘要】：目的 (1)以大腸桿菌(ATCC25922)作為微滲漏檢測標(biāo)志物,比較Bicon種植系統(tǒng)的成品基臺和個性化基臺在細(xì)菌封閉能力方面的差異。(2)通過生物力學(xué)測試,評測Bicon兩種基臺與種植體的連接強(qiáng)度。方法 (1)Bicon植體10顆(內(nèi)徑2.0 mm),隨機(jī)分為A(1-5號)、B(6-10號)兩組,向10顆種植體內(nèi)徑滴入等量大腸桿菌液,A、B組分別裝入Bicon成品基臺和個性化基臺,然后將標(biāo)本分別放入培養(yǎng)液中培養(yǎng),于6h、24 h、48 h和72 h時取種植體周培養(yǎng)液計(jì)算大腸桿菌菌落數(shù)。(2)Bicon種植體10顆(內(nèi)徑2.0 mm),隨機(jī)分為A、B兩組。A、B組分別裝入Bicon成品基臺和個性化基臺,用MTS Bionix858微力拉扭材料試驗(yàn)機(jī)進(jìn)行拉力和扭矩測試。結(jié)果 (1)A組的1、3、4、5號標(biāo)本在4個時間點(diǎn)種植體周圍培養(yǎng)液均未出現(xiàn)菌落。2號標(biāo)本在24 h以及之后的時間點(diǎn),種植體周培養(yǎng)液出現(xiàn)了少量菌落;B組種植體周圍培養(yǎng)液在5個時間點(diǎn)均出現(xiàn)菌落。兩組之間菌落數(shù)目差異具有統(tǒng)計(jì)學(xué)意義(P0.05)。(2)A組最大脫位力和扭矩均大于B組,且差異具有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論 (1)2.0 mm內(nèi)徑的Bicon種植體的成品基臺在細(xì)菌封閉能力方面強(qiáng)于個性化基臺。(2)2.0 mm內(nèi)徑Bicon種植體的成品基臺與種植體的連接強(qiáng)度優(yōu)于個性化基臺。
[Abstract]:Objective 1) to compare the differences of bacterial sealing ability between the finished and individualized base of Bicon planting system by using Escherichia coli ATCC25922) as a marker of microleakage detection. The connection strength between two kinds of Bicon abutments and implants was evaluated. Methods 10 implants were randomly divided into two groups, the inner diameters of 10 implants were dropped into the same amount of Escherichia coli solution. The two groups were loaded into the Bicon finished bed and the individualized base bed, respectively, and the two groups were randomly divided into two groups. Then the specimens were cultured in culture medium respectively. At 6 h, 24 h, 48 h and 72 h, the colony number of Escherichia coli was calculated. The Bicon implants were randomly divided into two groups: group A, B, B, and group A, B, which were loaded into Bicon base and individualized group, respectively. The tensile force and torque were tested by MTS Bionix858 microtension and torsion material testing machine. Results No colony was found in the culture medium around the implant at 4 time points, and no colony was found in the culture fluid around the implant at 4 time points in group A, and no colony was found in the culture fluid around the implant at 4 time points, and the second specimen was at 24 h and later time point. There were a few colonies in the peri-implant culture fluid of group B at five time points, and there was statistically significant difference in the number of colonies between the two groups. The maximum dislocation force and torque of group A were higher than those of group B, and the results showed that there was no significant difference between group B and group B in the number of colonies in group B.There was significant difference in the number of colonies between the two groups. The difference was statistically significant (P 0.05). Conclusion the finished Bicon implant with 2.0 mm inner diameter has better bacterial sealing ability than that of the individualized Bicon implant with 2.0 mm inner diameter. The connection strength between the finished bed and the implant is better than that of the individualized base.
