title: A cast metal core for a deformed implant body: case report.
abstract: The present report consists of a clinical evaluation of an osseointegrated implant using a cast metal core instead of abutment for a deformed implant body. The intramobile connector insert for the implant in the mandibular left first premolar region broke 7 years after the superstructure was attached to the implant system. The intramobile connector insert was replaced, and the prosthesis was reattached, but the new intramobile connector insert broke again 2 weeks later. A thorough examination confirmed deformation of the upper section of the implant body in the mandibular left first molar region. Breakage of the new intramobile connector insert in the mandibular left first premolar region was believed to be due to deformation of the implant body in the mandibular left first molar region. Therefore, a cast metal core was used to deal with the deformation of the implant body in this region. Although slight bone resorption was observed around the implant body after 5 years, no major problems were found in the implant body itself.
