Oral rehabilitation of edentulous maxilla is particularly difficult because of the lack of bone in correspondence of maxillary sinuses. Therefore, the surgeon is forced to place implants in sites where bone is more prevalent. In addition, patients require more frequently oral immediate rehabilitation in order to reduce the discomfort related to wearing a total denture. A viable solution to provide stability and retention of the prosthesis in a short time, is represented by the technique of intraoral welding systems supporting total denture or fixed prosthesis. This goal may be achieved thanks to the technique of welding titanium bars on implant abutments. In fact, the procedure can be performed directly in the mouth eliminating possibility of errors or distortions due to prosthetic procedures. This paper describes a case report and the most recent data about long-term success and high predictability of intraorally welded titanium bar in immediate loading implants.
A 56 year old male came to our clinic for an examination. A panoramic radiograph evidencing periodontal disease was performed. Subsequently periodontal teeth in maxilla were extracted. It was decided to stabilize his denture by the insertion of six implants in the maxilla, and a computer guided implantology surgery was programmed with the appropriate software. The insertion of the six implants was followed by screwing six abutments on implants. The patient was checked after two days, and fifteen days and during this period no problems were noted.
Titanium bars intraorally welded on prostheses is now a widely proven technology and allows the stabilization of fixed prostheses in edentulous ridges that otherwise could not be rehabilitated, improving the quality of the results, reducing the operative time, and giving greater comfort to the patients.
