Mandibular Reconstruction Based on the Concept of Double Arc Reconstruction

Abstract

The natural mandible has 2 arcs, the marginal arc and the occlusal arc. The marginal arc is situated along the lower margin of the mandible and affects the contour of the lower third of the face. The occlusal arc is situated along the dental arc and affects the stability of prosthodontics. The gap between these 2 arcs widens in the molar area. Our developed concept of "double arc reconstruction" involves making these 2 arcs for the reconstructed mandible. For the double-barrel fibula reconstruction, 2 bone segments are used to make both arcs. For reconstructions using the iliac crest, the double arc is made by inclination of the top of the bone graft toward the lingual side. Ten patients underwent double arc reconstruction: 2 underwent reconstruction with the double-barrel fibula, and 8 underwent reconstruction with the iliac crest. Four patients had a removable denture prosthesis, 1 had an osseointegrated dental implant, and 5 did not require further prosthodontic treatment. The shape of the reconstructed mandible after double arc reconstruction resembles the native mandible, and masticatory function is good with the use of a dental implant or removable denture prosthesis, or even without prosthodontics.
