Heating from mixed‐post configurations, measured at the screw–melon interface. Circles show heating for carbon posts, with one insulated post (right anterior, hollow circles) and three uninsulated posts (temperatures obtained at left anterior, filled circles) at the other locations. Triangles show heating for alumina posts, with one insulated alumina post (right anterior, hollow triangles) and three uninsulated posts (temperatures obtained at left anterior, filled triangles) at the other locations. Uninsulated posts show higher temperature increases than insulated posts, and alumina posts have higher heating than carbon posts.
