Sažetak
One of the methods of implantoprosthetic therapy of complete edentia/edentulousness of the lower jaw is the fabrication of a fixed bridge on implants. Such therapy assumes the placement of 4 to 6 implants in the interforamen area and construction of bridges on the implants. Such bridges are usually fixed with screws, rarely cemented, and distal cantilever are the rule.
The basic problem in screwed fixed superstructures is passivity. Because of the technological process of constructing metal superstructures, thermal changes are not unusual, which results in the occurrence of tension when fixing on the implant. Any tension is harmful and finally leads to mechanical complications of the superstructure.
Another problem is distal cantilever. As a general rule the length of the cantilever amounts to 2X, in which X represents the vertical length (space) between the last and the penultimate implant. This means that cantilever can be longer, which is better spatial arrangement of the implants. Other less important problems with cantilevers are of a technical nature and can be avoided by correct shaping of the superstructure.
The presentation gives an evaluation of the success of therapy with screwed fixed bridges in the lower edentulous jaws. The period of monitoring ranges from 3 to 5 years, with analysis of complications in the same time period. Mechanical and biological complications are separately analysed. The frequency and character of mechanical complications are analysed. The results of the research provide guidelines for safer and more successful clinical work with such types of prosthetic superstructures on implants.
