Objectives: The aim of this study was to compare the satisfaction index of 10 randomly chosen patients operated on in our service with two different techniques for mentum advancement. Introduction: Custom facial chin implants are made from bespoke solid PMMA. A prosthesis is planned and manufactured for each patient, making each one have a unique result. Implants have two basic functions: to deliver quality of life and aesthetics, which has an impact on the patient's emotional and social life. Thus, we understand that facial implants are a lasting and advantageous alternative to aesthetic procedures such as facial harmonization with hyaluronic acid (fillers) and silicone implants in the face region. Materials / method: We carried out a retrospective study with a series of cases operated on by our team, comparing the satisfaction index using a visual analogy scale (VAS 0-10), with five (05) patients undergoing chin advancement surgery with facial prostheses, and five (05) patients who had silicone implants. All ten (10) patients had the intention of harmonizing the face. The patients were submitted, after 12 months of surgery, to indicate their index of satisfaction with the procedure. Results: Of the five (05) patients who underwent chin advancement surgery with personalized chin prostheses, 04 indicated a satisfaction rate of 10 (VAS 0-10), and 01 indicated a satisfaction of 8. The patient (VAS-8) reported that he still had a slight edema and asymmetry. Of the (05) patients who underwent silicone implants, 02 indicated a satisfaction rate of 10 (VAS 0-10), and 02 indicated 7. Both (VAS-7) patients reported that they still had mobility and asymmetry. And 01 patient indicated satisfaction 0, as the prosthesis would have to be replaced, due to bone resorption. Conclusion: As noted in the literature, our study also presented a case of bone resorption with silicone implants. In customized facial chin implants, we observed a high biocompatibility. They are produced in PMMA, and surgically fixed with 2.0 system screws. This stability reduces the chances of promoting bone resorption in the implant region.
