Dental implantology drill bit

to prepare the bone in cases where it is necessary to sink the spherical part of the fixture. When placing a ORBIT fixture in soft bone (D IV) the surgeon should consider undersizing osteotomy. The final drill diameter should be limited to the one immediately smaller than the diameter that should have been used. When placing an ORBIT fixture in hard bone (D I) do not underpre- pare the osteotomy site. The surgeon should consider to use as final drill diameter the one immediately bigger than the diameter that should have been used, stopping at the second laser mark. This will create an osteotomy of proper dimension in the dense cortical bone without any under- preparation.
