Would augmentation genioplasty using patient-specific PEEK (Polyether Ether Ketone) implant meet patient’s expectations?

Introduction: Patient-specific implants become very valuable in restoring facial contours, including the chin area. Evaluation of patient satisfaction with the esthetic results should be a primary concern. Aim of study: To evaluate the success of augmentation genioplasty using patient-specific PEEK (Polyether Ether Ketone) implant in meeting patient’s expectations. Methods: Seven patients were enrolled in this study. They were all having deficient chin that was managed by augmentation genioplasty using patient-specific PEEK implant. Preoperative clinical evaluation was performed for all patients. With the help of MIMICS and 3-MATIC soft wares, diagnosis, virtual planning and final implant design were done. Finally, STL file was sent for milling using PEEK material. Under GA, PSI was inserted through an intra-oral vestibular approach and fixed to the underlying bone using mini-screws. Patient expectations were evaluated by Face-Q questionnaire. Result: The study was conducted on 7 cases, 3(42.9%) of which were males and 4(57.1%) were females. The mean age of the cases was (22.00±1.29) years. All patients showed high degree of contentment with the procedure. Conclusions: Patient-specific PEEK implant can be used for chin augmentation with good esthetic results close to that of patients’ expectations.
