Ensuring adequate approximal contacts when performing class 2 composite resin restorations is a significant challenge for the dentist. Fabrication of custom composite cylinders for placement into prepared cavity preparations enables the dentist to wedge the matrix band firmly against adjacent teeth, as well as eliminating the curing contraction variable that occurs when composite restorations are placed. Thus, predictable approximal contacts are obtained when class 2 composite restorations are completed.
在进行二类复合树脂修复时，确保足够的邻面接触对牙医来说是一项重大挑战。制作定制的复合树脂圆柱体并将其放置在预备好的窝洞中，能使牙医将成形片带牢固地楔紧在相邻牙齿上，同时消除复合树脂修复体放置时出现的固化收缩变量。因此，在完成二类复合树脂修复时可获得可预测的邻面接触。
