Modifications in the design and fabrication of mandibular osseointegrated fixed prostheses frameworks

This article presents the advantages of design modifications and fabrication techniques for mandibular osseointegrated fixed prostheses. These design features provide definite mechanical advantages and access for oral hygiene maintenance. A review of implant surface properties is presented that affect bacterial plaque and food debris adherence. The suggested design involves a lingual contour of the cast alloy suprastructure to yield an environment for reduced plaque and debris accumulation. The right angle cross-section ensures strength and increased stress distribution in structurally compromised areas when compared with conventional implant framework designs.
