Abstract
Mandibular flexure is a phenomenon generated by the action of the muscles of mastication
and other muscles in the head and neck region which can lead to prosthetic and biological
complications such as pain, material fracture, and bone loss around dental implants.
To avoid such complications, dividing the mandibular prostheses into 3 short-span
prostheses or sectioning at the midline has been suggested. This clinical report presents
the management of an edentulous patient with clinically detectable mandibular flexure
treated with a 1-piece metal-free complete arch implant-supported prosthesis.
