A multiplicity of therapeutic possibilities is available in modern implantology. For using implants in severe periodontal cases a two step procedure is recommended. Immediate loading of implants after extracion was rejected predominantly. In the past 3D-planning and guided templates were indicated for edentulous or semitoothless jaws. For transdental implant planning and guided surgery a new approach is presented. Transdental Guided Implant Planning and Positioning (TdGIP) permits an immedate implantation post extractionem and immedate funcional loading with crown and/or bridges. The procedure was flanked by antimicrobiotial photodynamic therapy and YSGG laser treatment.
