The article aims to provide a broad and as far as possible complete picture of the functions of the Drill Bone Expander (D.B.E.) System in controlled bone expansion methods.
The concept of prosthetically guided implantology is now a fundamental assumption of modern implantoprosthesis, which is applied in all cases that dental surgeons have to deal with every day. This means that the position of the implant must not be dictated by where the surgeon finds an adequate quantity of residual bone tissue, but rather by scrupulous prosthetic planning, conducted a priori, which establishes the ideal point for then having a correct unloading of the forces, emergence profile, tissue management, etc.
It is also equally certain that one of the major anatomical limiting factors that can prevent the correct positioning of the implants is horizontal and/or vertical bone reabsorption.
In the light of these two factors it is therefore clear that, when in the presence of bone loss such as to preclude an adequate implantoprosthetic rehabilitation, it is necessary or, even more, indispensable to resort to regenerative techniques suitable for restoring a new and sufficient bone anatomy.
For this purpose the use of the Drill Bone Expander D.B.E. System has proven, in our daily clinical practice, to be an extremely useful, simple and above all versatile method that is able to provide reliable support in many situations where we have had to resort to bone regeneration techniques.
One of the most frequent situations that the surgeon has to deal with and in which the use of the D.B.E. System may be fundamental is certainly that of post-extraction implants. Very often, especially when the lack of a sufficient apical bone thickness or an inadequate density prevent the insertion of longer implants, the greatest difficulty lies in achieving a minimum primary stability that guarantees perfect osseointegration of the implant. This publication presents an interesting series of clinical cases.
