An in vitro study was conducted to quantitatively compare the marginal adaptation of temporary crowns made from Protemp material with those made from Scutan, Provisional, and Trim materials. A direct technique was used to make temporary restorations on prepared teeth with an impression as a matrix. Protem, Trim, and Provisional materials produced temporary crowns of comparable accuracy. Crowns made from Scutan material had open margins.
进行了一项体外研究，以定量比较由Protemp材料制成的临时冠与由Scutan、Provisional和Trim材料制成的临时冠的边缘适应性。采用直接技术，以印模为基质在预备牙上制作临时修复体。Protem、Trim和Provisional材料制作的临时冠具有可比的精度。由Scutan材料制成的冠边缘不密合。
