OBJECTIVE
The physical properties and wettability of 3-D printed Polyethylene terephthalate - glycol (PET-G) and Poly(lactic) acid (PLA) dental sectional matrices were investigated.
METHODS
Experimental matrices was designed in a rectangular shape one-side depression corresponds to gingival col and without sharp edges and printed on FDM machine Ender Pro 3 (Creality, Shenzhen, China). The physical textures, thicknesses, water contact angles were compared to conventional stainless steel (SS) matrix.
RESULTS
PETG and PLA sample matrices were clinically single-side smooth compared to SS matrix. PETG specimens had uniformly 0.055 mm whereas PLAs were non-uniformly ∼0.065-0.075 mm in thickness. The mean ± standard deviation (SS) of contact angle for SS was 78.29 ± 0.18, for PETG was 72.09 ± 0.94, for PLA was 73.03 ± 1.17.
CONCLUSION
PETG and PLA dental matrices might have desirable properties: being hydrophobic, non-charged, easy to manufacture and mimicking the gingival col depression in the dental interproximal contact area.
目的
研究3D打印的聚对苯二甲酸乙二醇酯-二醇（PET-G）和聚乳酸（PLA）牙科切片基质的物理性质和润湿性。
方法
将实验基质设计为矩形，一侧凹陷对应牙龈乳头间隙且无尖锐边缘，并在FDM机器Ender Pro 3（中国深圳创想三维）上打印。将其物理纹理、厚度、水接触角与传统不锈钢（SS）基质进行比较。
结果
与SS基质相比，PETG和PLA样品基质在临床上单侧光滑。PETG标本厚度均匀为0.055毫米，而PLA标本厚度不均匀，约为0.065 - 0.075毫米。SS的接触角平均值±标准差为78.29 ± 0.18，PETG为72.09 ± 0.94，PLA为73.03 ± 1.17。
结论
PETG和PLA牙科基质可能具有理想的特性：疏水、不带电、易于制造且能模拟牙邻面接触区的牙龈乳头间隙凹陷。
