Description
A screw-retained implant crown has a small access hole that must be filled invisibly. Four authors compared three fillings for that hole in the lab: flowable composite alone, an opaque layer under flowable composite, and a porcelain plug. Samples were soaked and temperature-cycled in coffee, orange juice, and water to mimic months in the mouth.
Color was measured at several stages against the surrounding crown. Material choice mattered. The porcelain plug started closest in color but ended furthest off after the full cycling, while the layered composite held its match better. Porcelain plugs are also fiddly to make and seat in a tiny hole. The authors therefore recommend the simpler recipe: an opaque composite layer under a flowable one, which hides the dark metal beneath and keeps the color honest.
