Mandibular dental implant placement immediately after teeth removal in head and neck cancer patients.

Background: Little is known about immediate implant placement in head and neck cancer patients. We studied implant survival and functional outcomes of overdentures fabricated on implants placed immediately after removal of the lower dentition during ablative surgery or preceding primary radiotherapy (RT).

Methods: Inclusion criteria were primary head and neck cancer, dentate lower jaw, and indication for removal of remaining teeth.
