They share one rigid rotation and translation plus recorded individual vertical lifts to align the cusp heights. No scaling, smoothing, subdivision or root replacement is applied. See source-transform.json. The crown retains the source occlusal morphology with a 0.65-unit lift and a taller, newly authored cervical body extending to a lowered titanium shoulder, rounded annular margin, fitted inner titanium-base cavity, occlusal screw access and a separate surface-matched closure. Bone, gingiva, instruments, implant components, procedural surface textures and tissue color attributes are independently authored teaching assets. Gingival socket contours are derived from sections of the attributed tooth meshes. The combined model and editable source are distributed under CC BY-SA 2.1 Japan. There is no Open Dental CAD crown geometry in this version. Editable source and regeneration script: source.zip (same directory). No manufacturer photos, videos or proprietary CAD are included. The model is not clinically validated or patient-specific.
