The anterior teeth (crowns must be intact) that have been removed for various reasons are soaked in formalin solution for half an hour to remove the roots, remove the coronal pulp, rinse, and soak in 95% alcohol for later use. Conventional preparation of abutments, the production of pile spikes, matching the size of the color appropriate spare crown, grinding to make with the abutment root anastomosis, and symmetry with the healthy lateral teeth, carefully tune (occlusion). Fully meet the requirements, the zinc phosphate cement pile peg, mixing compound resin filled crown cavity, and coated on the abutment root surface docking cement, remove the excess resin extrusion, until the resin is completely hard solid After further transfer (occlusion).
