Manual method of determination of SafA using OsiriX™ 3D-MPR mode. First, 2 orthogonal planes containing the safety margin points (green points) are identified. The intersection of these 2 planes simulates the implant site (IE). Then, circles of the same diameter as the simulated implant are positioned around the safety point (green circles). Tangent lines to each circle passing through the insertion point are used to measure SafA (red arrows)
