BACKGROUND
The temporary cement remaining inside the dental prosthesis can act as a source of microbial colonization and contamination and decrease the final cement retention. Consequently, complete removal of temporary cement before permanent cementation is suggested. This study aimed to assess the effect of different cleaning methods for removing temporary cement on the tensile bond force (TBF) of permanently cemented implant-supported zirconia copings.
MATERIALS AND METHODS
In this study fifty titanium abutments were screwed onto 50 analogs with 30 Ncm torque into in acrylic resin blocks. Each abutment was scanned separately, and 50 zirconia copings were designed and milled. Permanent resin cement was used to cement copings of control group ( = 10). Copings were divided into two temporary cementation types that in each group, two cleansing methods were used: Temp-S (temporary cement with eugenol and sandblasted after debonding), Samples of the control group were placed in the universal testing machine, and the TBF values were recorded. Samples of the test groups after debonding and cleaning the abutments were subjected to cement with permanent resin cement, aging, and removing. Levene test, two-way analysis of variance (ANOVA), and Tamhane post hoc tests were applied. α = 0.05.
RESULTS
The highest and lowest TBF values were found for the TempNE-SU (554.7 ± 31.5 N) and Temp-S (492.2 ± 48 N) groups, respectively. The two groups of isopropyl alcohol baths in ultrasonics in combination with sandblasting showed statistically higher TBF values than the other two groups that used only sandblasting ( < 0.001) and had similar values compared to the control group.
CONCLUSION
Sandblasting combined with immersion in an ultrasonic bath containing isopropyl alcohol resulted in statistically similar values to the values of cementation with resin cement from the beginning. However, cleaning the inside of the copings only by sandblasting method reduced the values of the final retention force in comparison to cement with permanent resin cement from the beginning.
背景
留在义齿内的临时粘固剂可成为微生物定植和污染的来源，并降低最终的粘固剂固位力。因此，建议在永久粘固前彻底清除临时粘固剂。本研究旨在评估不同清洁方法去除临时粘固剂对永久粘固的种植体支持氧化锆基台拉伸粘结力（TBF）的影响。
材料与方法
在本研究中，将50个钛基台以30 Ncm的扭矩拧入50个丙烯酸树脂块模拟体中。每个基台单独进行扫描，并设计和研磨50个氧化锆基台。对照组（n = 10）使用永久树脂粘固剂粘固基台。基台分为两种临时粘固类型，每组使用两种清洁方法：Temp-S（含丁香酚的临时粘固剂，脱粘后喷砂），对照组样本置于万能试验机中，记录TBF值。试验组样本在脱粘和清洁基台后，用永久树脂粘固剂粘固、老化并去除。采用Levene检验、双向方差分析（ANOVA）和Tamhane事后检验。α = 0.05。
结果
TempNE-SU组（554.7±31.5 N）和Temp-S组（492.2±48 N）的TBF值分别为最高和最低。两组异丙醇超声浴结合喷砂的TBF值在统计学上高于仅使用喷砂的其他两组（P < 0.001），且与对照组的值相似。
结论
喷砂结合浸入含异丙醇的超声浴在统计学上与从一开始就用树脂粘固剂粘固的值相似。然而，与从一开始就用永久树脂粘固剂粘固相比，仅通过喷砂方法清洁基台内部会降低最终固位力的值。
