Management of fractured components in Implant prosthesis- A Case Report.

Abstract

Dental implant treatment is a fast-growing field witnessing high success rate due to its osseointegration feature. Nevertheless, there are some complications relating to biological (Peri-implantitis; unsuccessful osseointegration) and mechanical (relating to implant prosthetic components) factors. Some of the mechanical factors which lead to failure are Prosthetic screw loosening, Prosthetic screw fracture, implant fracture, and framework fracture. Fracture of implant is a nemesis for the prosthodontist. Identifying the etiology and appropriate planning bring success to the treatment. This case report is about re- restoration of failed implant prosthesis with fracture at the abutment internal helix due to overload and active fixation. Multiple clinical difficulties were encountered (limited mouth opening, accessibility) during the procedure which were overcome by intra- orally adjusting the abutments (for parallelism and occlusal clearance) and proceeded with abutment level impression. The retainers were fabricated with an access hole for future retrievability in case of failure. Re-restoration with minimal intervention like modification of abutments intra-orally can be considered for a successful outcome. Sometimes, simpler choices may provide solutions for complex challenges.
