The trial's goal was to assess the retentiveness of specially formulated implant cement besides comparing it to dental cements that are widely utilized by means of implant systems.
Twenty implant analogs were implanted in auto-polymerizing acrylic resin blocks and bonded to titanium abutments. Fifty uniform copings were waxed and cast unswervingly onto the abutment. (1) Resin-bonded zinc oxide eugenol cement, (2) purposefully designed implant cement, (3) zinc phosphate cement, (4) zinc polycarboxylate cement, and (5) glass ionomer cement were the cements used. Following cementation, each sample was pulled out by utilizing a widespread testing machine, and the stresses necessary to confiscate the crowns were recorded. The ANOVA and Bonferroni tests were used to examine the mean values and standard deviations of cement failure loads.
Zinc polycarboxylate cement had the peak mean cement failure load, followed by glass ionomer cement. Zinc phosphate cement had the next highest mean cement failure load, followed by resin-bonded zinc oxide eugenol cement. The mean cement failure load for Premier implant cement was the lowest. The difference in mean cement failure loads across the groups was statistically significant ( < 0.001).
The findings do not imply that one type of cement is superior to another, but they do present a ranking directive of cements based on their capacity to maintain the prosthesis and facilitate retrievability.
该试验的目标是评估特制种植体黏固剂的固位力,并将其与通过种植系统广泛使用的牙科黏固剂进行比较。
将20个种植体代型植入自凝丙烯酸树脂块中,并与钛基台相连。制作50个均匀的顶盖,直接在基台上用蜡型铸造。使用的黏固剂有:(1)树脂黏结氧化锌丁香酚水门汀,(2)特制种植体黏固剂,(3)磷酸锌水门汀,(4)聚羧酸锌水门汀,(5)玻璃离子水门汀。黏固后,使用通用测试机拔出每个样本,并记录拔除牙冠所需的应力。采用方差分析和Bonferroni检验来分析黏固剂破坏载荷的平均值和标准差。
聚羧酸锌水门汀的平均黏固剂破坏载荷最高,其次是玻璃离子水门汀。磷酸锌水门汀的平均黏固剂破坏载荷次之,其次是树脂黏结氧化锌丁香酚水门汀。Premier种植体黏固剂的平均黏固剂破坏载荷最低。各组间平均黏固剂破坏载荷的差异具有统计学意义(<0.001)。
研究结果并不意味着一种黏固剂优于另一种黏固剂,但它们确实根据黏固剂维持修复体和便于取出的能力给出了黏固剂的排序指南。
