Height Parallelism of Implants in the Treatment of the Edentulous Mandible with Ball-Retained Overdentures: A Technical Note

The objective of this report is to present a device to achieve equal platform height in the vertical axis to allow the spherical abutments to work correctly in mandibular overdentures retained with 2 implants. The device is fabricated over plastic castable abutments, with a plate perpendicular to the implant platforms and located at the top of the platform height. Once implants are inserted, the device is screwed to an implant and allows evaluation of the height of the platforms. Parole chiave: edentulous arch, overdenture, surgical template
