Bone Density _ D1,D2, D3,D4
D1 (Type I)
-dense cortical bone and is the highest in the density
- Mandibular Anterior area
- Oak/Maple-like texture
D2 (Type II)
- coarse trabecular bone surrounded by thick porous cortical bone
- Mandibular Anterior area
- Mandibular Posterior area
- Maxillary Anterior area
- Spruce/White pine-like texture
D3 (Type III)
- fine trabecular bone surrounded by thin porous cortical bone
- Maxillary Posterior area
- Balsa wood-like texture
D4 (Type IV)
- fine trabecular bone with almost no cortical bone
- Styrofoam-like texture
