Objective: The purpose of this presentation is to show the difficulty in prosthetization of a clinical case with a pronounced atrophy of the upper jaw and the various types and nature of restrictions imposed by the requirements of the patient.
Methods: The clinical analysis, surgical protocol and prosthetic solution are presented in the treatment of 72 year-old woman with a pronounced atrophy of the upper jaw.
OPG, standard CT of the upper jaw was used in the planning and a special surgical template was fabricated, helping us to find intraoperatively the exact locations of implants. The preliminary analysis of the number, height and diameter of intraossal implants helped us to find the exact prosthetic solution in this clinical case. The preparation of the implant bed was done by conical osteotomy in order to expand and condense the existing bone, which allowed us to use endoossal implants with a possible maximum size in a very limited maxillary volume and the reluctance of the patient to use other methods and surgical techniques. Conical threaded and self-tapping intraossal implants were used, placed according to a classic two-stage methodology with a flap and a long-term functional loading after a period of four months.
Results and Conclusion: The applied surgical and prosthetic solution allowed us to achieve a good functional and aesthetic rehabilitation in this case of severe atrophy of the upper jaw, following a number of restrictions imposed on us by the reluctance of the patient to use other surgical solutions. This shows that  in the case of severe atrophy of the upper jaw, a good clinical result can be achieved. For this reason, the use of CT,a well-planned surgical template, sufficient preparation ,the maximum use of available bone volume and the choice of  a good prosthetic solution is very important.

Key words: dental implants,osteotome techniques.
