Implant-supported bar overdentures in patients treated surgically for head and neck cancer: Two case reports

Nadine Omeish et al. Clin Case Rep. .

Abstract

Prosthetic rehabilitation of patients who have undergone head and neck cancer (HNC) surgery could be very challenging. The aim of this article is to present two HNC clinical cases rehabilitated with implant-supported removable complete dental prosthesis with different types of CB.

Keywords: connecting bar; dental implants; head and neck cancer; implant‐supported prosthesis; overdentures.
