The aim of the present study is to show the aesthetic and functional advantages of a “one to one” immediate-loading protocol, in terms of proper distribution of occlusal loads.

MATERIALS AND METHODS:
The clinical case concerns a 54-year-old male patient with a mobile prosthesis. At first, 6 implants (self-tapping with deep spirals and wrinkled surface) were inserted to fill the gaps of the mobile prosthesis.

Then, we performed a crestal sinus lift and 5 implant insertions to restore the normal occlusion. In the immediate postoperative period of the first 6 implants, which had an excellent primary stability, we placed a temporary prosthesis acting as a surgical guide; the case was finished by zirconia-ceramic single crowns.

RESULTS:
X-ray examination after 6 months revealed good implant stability, without healing defects and bone dehiscence and with an excellent morphology of peri-implant soft tissues.

DISCUSSION AND CONCLUSIONS
The choice of immediate loading has an aesthetic advantage, because allows for an immediate resolution of edentulism and an excellent mucogingival aspect, and a functional advantage, because adequate loads in the immediate postsurgical period lead to osseointegration;
“One to one” protocols allow to transfer the occlusal load on every implant pillar, with a reduced risk of overload and implant loss. They also allow to achieve an appearance similar to natural teeth and an easier oral hygiene.
