Applications of PEEK in implant retained finger prosthesis

This article presents and describes the use of polyether ether ketone (PEEK) to fabricate an abutment in implant retained finger prosthesis using computer-aided design and manufacturing (CAD/CAM) technology. The titanium implant was scanned by conventional implant impression coping and a model was fabricated from computer software and the height of the abutment was increased to 15 mm in length. The custom designed implant abutment for the finger prosthesis was milled with PEEK and it was tried on the patient. After its use, tissue reactions were absent. The thumb prosthesis was fabricated by silicone connected with abutment by polyvinyl siloxane which had good retention and function. PEEK abutment was fabricated for the implant retained finger prosthesis using 3D technology. PEEK abutment had better biocompatible with peri-implant tissue than metal alloy abutment and improved the retention.
