Prosthetic rehabilitation in cases of Kennedy class 4th, particularly when the from gap is extensive, presents problems of both aesthetic (lack of front teeth) and functional nature that are not easy to solve. On one side a mixed dental and mucosa support must be obtained while on the other over-loading of the abutment teeth must be avoided by distributing force axially and unformly. This is done by using a special type of prosthesis described here where force is distributed by means of wires. Cases treated like this and followed up have shown positive results as regards both clinical and mechanical results.
