Response surface plots showing effects of implant placement depth (Depth), gingival height of titanium base (TiBase), and abutment taper degree (Taper) on standard deviation of density in (a–c) cortical and (d–f) cancellous bone regions: (a) depth and TiBase in relation to cortical bone; (b) depth and Taper in relation to cortical bone; (c) TiBase and Taper in relation to cortical bone; (d) depth and TiBase in relation to cancellous bone; (e) Depth and Taper in relation to cancellous bone; (f) TiBase and Taper in relation to cancellous bone.
