title: Bar attachments for overdentures with nonparallel abutments.
abstract: Bar attachments are easily fabricated and provide increased retention and support for overdentures. Nonparallel root abutments can preclude the routine use of bar attachments unless modifications are made in the design. This article reviews several existing techniques to successfully fabricate bar attachments in overdenture patients with nonparallel abutments. In addition, three alternative methods are presented for placing bar attachments on abutments with divergent roots.
