To understand how Basal-implants are able to avoid bone grafts and sinus lift we need to understand basal bone.
Bone maintains its shape, as long as there is function associated with it. The alveolar bone appears and disappears with the presence of teeth. In contrast, the basal-bone is maintained by the stimulus of the muscles inserted into it. These muscles always maintain the form, shape and density of the basal bone. The bone density is very high where muscles are inserted on the bone surface. This bone is very resistant to resorption and infection.
Any implant engaging the cortex of basal bone is termed “Basal Implant”.
Basal implants are the most advanced implants, successful for any condition of bone. It can be used on patients with any bone density and any bone volume. These implants engage the highly dense cortical bone which has least propensity for resorption. Basal-bone is present in everyone, despite severe bone loss due to gum disease or loss of teeth. As such, they are highly recommended for patients who are in need of bone grafts and sinus lift.
There are no absolute contraindications for basal-implants.
Less bone volume needing bone grafts and sinus lift
Less bone density
Gum disease and infected teeth
Regular bone which will eventually shrink with time
