Scanning electron microscopy observations of osseointegration failures of dental implants that support mandibular overdentures.

Aim: : Investigating possible failure causes of mandibular implants after their immediate loading with an overdenture retained with bilateral bar attachments, using scanning electron microscope.

Patients And Methods: Twenty edentulous male patients were included in the present study. Each patient had 2 fixtures inserted in the canine and the first molar areas on each side of the mandible.
