Use Laser-Lok healing abutments when a Laser-Lok abutment restoration is planned to inhibit epithelial downgrowth, establish a soft tissue seal and protect the bone. After removing a Laser-Lok healing abutment to make an impression, use a new Laser-Lok abutment (healing or final) to establish the soft tissue connection again. Flares to 4.5mm in diameter. Hand-tighten with the .050" (1.25mm) Hex Driver.
