• 1) The vertical implant site dimension is measured over the basal bone surface respectively over the roof of the mandibular canal according to the dental scheme site by site. Every site is divided basically in 4 categories:
• 1. As a basic assumption, the implant site is at the base larger than crestal. Thus, the shape in unfavorable cases is more or less acuteangled triangular, in favorable casesz a quadrangular or oviform cross-section of implant sites with a multiplicity of individual variations results.
• 2) The transversal implant site dimension is clinically determined 5mm below the bony al.,eolar crest site by site. It is judged to be sufficient in case of 5mm.
• 3. The width of implant sites is measured with clinical procedures easily (by direct measurement and probing of gingiva width).
• A: Abundant height over 20mmz identification color code blue.
• C: Critical height under 15mmz identification color code yellow.
• S: Sufficient height over 15mm, identification color code green.
