Abstract
A mandibular overdenture supported by 2 implants is an effective treatment alternative for the maladaptive denture wearer. The implants may be either splinted, using a bar, or nonsplinted and retained by attachments, such as balls or magnets. When the use of a ball attachment is contemplated, the implant abutments should be parallel to one another along the path of insertion. The following report describes the procedure to correct a nonparallel implant abutment to retain a mandibular overdenture.
