背景/目的通常使用诸如乙烯醋酸乙烯酯和聚烯烃的护齿片材料。然而，在聚烯烃的加热期间片材温度的变化尚未确定。本研究的目的是检查在加热过程中片材温度的变化，并检查片材材料的真空成型护口器特性。材料和方法所用的护口器材料为4.0 mm的乙烯醋酸乙烯酯和聚烯烃片材。当加热后片材的中心从基线移位10、15和20 mm时，测量两种材料的片材温度。通过双向方差分析分析了不同板材的板材温差。当加热温度达到100°C时，使用乙烯乙酸乙烯酯片材和聚烯烃片材真空成形片材。在中切牙和第一磨牙处测量护齿厚度和适合度。结果随着悬挂距离的增加，乙烯醋酸乙烯酯片的片温逐渐升高（P<0. 05），聚烯烃片的片温无明显变化。乙烯醋酸乙烯酯片材组中切牙和第一磨牙处的真空成型护齿厚度大于聚烯烃片材组（P<0.01或P <0.05）。乙烯醋酸乙烯酯片材制成的护齿套与聚烯烃片材制成的护齿套的贴合性没有差异。结论乙烯醋酸乙烯酯片材和聚烯烃片材在加热过程中护齿套片材温度的变化不同。与具有更好贴合性的聚烯烃片材相比，乙烯醋酸乙烯酯片材保持真空成型护齿套厚度。
Background/AimMouthguard sheet materials such as ethylene vinyl acetate and polyolefin have been used commonly. However, the change of the sheet temperature during heating of the polyolefin has not been determined. The aim of this study was to examine the change of the sheet temperature during heating and to examine the vacuum‐formed mouthguard characteristics for the sheet materials.Materials and methodsThe mouthguard materials used were 4.0‐mm sheets of ethylene vinyl acetate and polyolefin. The sheet temperature of the two materials was measured when the center of the sheet was displaced by 10, 15, and 20 mm from the baseline after heating. Sheet temperature differences by sheet materials were analyzed by two‐way analysis of variance. The sheets were vacuum‐formed when the heating temperatures reached 100°C using ethylene vinyl acetate sheet and polyolefin sheet. Mouthguard thickness and fit was measured at the central incisor and the first molar. Differences in the thickness and fit between the sheet materials were analyzed by two‐way analysis of variance.ResultsThe sheet temperature of ethylene vinyl acetate sheets became higher as the hanging distance became larger (P<0.05), but that of polyolefin sheets was not different. The thicknesses of the vacuum‐formed mouthguard at the central incisor and the first molar were greater in the mouthguards formed by ethylene vinyl acetate sheets than that with polyolefin sheets (P<0.01 orP<0.05). The fit of the mouthguard was not different between mouthguards formed by ethylene vinyl acetate sheets and that formed by polyolefin sheets.ConclusionsThe change of mouthguard sheet temperature during heating was different between ethylene vinyl acetate and polyolefin sheets. The ethylene vinyl acetate sheets maintained the vacuum‐formed mouthguard thickness in comparison with the polyolefin sheets with a better fit.
