Endosseous implants for total support and retention of a complete mandibular removable prosthesis.

This is a clinical report illustrating and discussing the use of endosseous root-form implants, both anterior and posterior to the mental foramen, in support of three separate Hader bars which in turn provide total occlusal support, resistance, and retention for a conventionally fabricated full mandibular overdenture. Principles of design, advantages, and disadvantages are listed.
