Kulzer's HeraCeram® is a high-fusing porcelain-veneer used for conventional bonding to ceramic metals for alloys in a CTE range of 13.5 to 14.9 x 10⁻⁶K⁻¹ (25-500 °C) with a stabilised leucite structure.
The HeraCeram® Special technique builds up metal-free crown margins using shoulder ceramics, inclusive of 7 HM and LM margins.
The Margin LM is a low-fusing material used to add, build up and correct ceramic margins after the veneering is complete, i.e. post glaze firing. Due to the low firing temperature of 790°C, the materials can also be used for correction e.g. the contours, pontics or contact areas. LM1–6 are coordinated with the respective shades as shown in a shade chart, whereas LM7 is also referred to as bleach. It is a whitish opaque shoulder ceramic with increased fluorescence and is used for masking dark areas (discoloured tooth structure) and modifying the brightness and transparency of LM material.
