inimally invasiv Minimally invasive preparation 1 2 3 Initial situation Minimally invasive preparation for indirect restoration with veneers (11-21-22). Fabrication of the master model with removable dies made of Exakto-Form polyurethane resin. Wax-up: The shape and texture of the wax model needs to include all details of the final restoration in order to reproduce them accurately in the compacted silicone key (using composite). 12
e preparation 4 5 6 Fabrication of the key made of transparent silicone visio.sil (shore hardness 60). An optimal hardness silicone should be selected in order to avoid damaging the wax model. The silicone key should be hardened at a pressure of 2.5 bar to avoid inclusion of air and ensure maximum precision of the duplicate. Preserving the wax model enables the assessment of the layer thickness of wax to composite during inverse layering. Once the silicone has hardenend and the individual dies have been adequately insulated, the inverse layering technique is carried out using crea.lign. Depending on the type of reconstruction, layering starts at the incisal edge. The effect materials are applied with a small brush. The Bleach material, for example, is recommended for young teeth. A pre-curing cycle (2-3 sec.) using a hand lamp is required after each individual layer to avoid individual effects mixing with other materials or with each other. 13
