The introduction of microsurgery for surgical endodontics minimizes trauma and enhances the outcome of results. When using magnification and illumination resected roots reveal intricate anatomical details. In conjuction with ultrasonic root-end preparation and tight sealing of the root end cavity with biocompatible materials, the requirements for mechanical and biological success are more adequately fulfilled. Microsurgery alone will not accelerate epithelial healing rates, but through perfect tissue adaptation of wound edges, it can create smaller distances for epithelial migration during the healing process. More rapid soft tissue healing is a result of reduced tissue trauma and enhanced wound closure after microsurgical procedures. To achieve these goals, several measures are necessary, including accurate preoperative treatment planning for the condition and quality of the tissue to be manipulated. Minimal trauma should be inflicted during incision and raising of the flap.
