Abstract
In atrophied edentulous mandible cases, conventional denture systems present many treatment problems and difficulties. Although subperiosteal implants are very good procedures for these patients, some problems have been found in the conventionally designed subperiosteal implants. The tripodial subperiosteal implant (TSI) developed by Linkow is very effective and safe for the treatment of such cases. But the material nature and procedure to fit it to the mandibular surface should be improved to provide desirable results. Therefore,we used pure Titanium instead of Co-Cr-Mo alloy and divided the frame into 2 parts and 1 endosseous blade.
They were connected together with a mesostructure bur and held by 4-Meta resin. We named it modified TSI. It was adopted clinically and there were no disturbances of speech or mastication about 10 months after completion of dental implantation.
