[Use of endodontically treated teeth in removable partial dentures].

In our study, cases where teeth with excessive crown loss served as abutments, where examined in Kennedy Class II modification 1, that have tooth and tissue support on removable partial dentures which were constructed with the same design. Our study aims to examine, how vertically directed forces are transmitted to the supporting tissues by using photoelastic method. Teeth with case post and core appliances were used as abutments for removable partial dentures. Vertical loading procedure following the construction of removable partial dentures with the same design, revealed distribution of force over dentulous and edentulous ridge areas. When a comparison between endodontically treated and sound abutment teeth, was made, we had the conclusion that teeth with excessive crown loss can successfully serve as abutments for partial dentures, because the results of our finding exhibited no significant difference.
