Objectives: The aim is to determine the possibility and effectiveness of using individually selected and 3D-printed mandibular implants in the long term in patients with microgenia, to investigate their quality of life and satisfaction with the aesthetic result. Introduction: Reduced chin, which in science is called microgeny, is a significant aesthetic problem. There are several methods for assessing a poorly protruding chin, but most of them are inaccurate when it comes to choosing the right size and shape of the implant. The choice is also complicated by the standard sizes of commercially available chin implants. Most implant manufacturers offer only three or four categories of implants (small, medium, large, etc.) that vary in size from one company to another. Our paper discusses a new approach to accurately determining the size and shape of the chin implant. Materials / method: The study was conducted in 14 patients, women – 9 (64.3%), men - 5 (35.7%). The mean age of the patients was 25.2 ± 5.3 years, it was the main group who underwent chin augmentation by using 3D imaging and printing to create a custom fit PEEP implants that was fixed by titanium screws. The control group - 38 patients who underwent chin augmentation by standart silicone implants. In both groups we used intraoral incision, that closed by Vicryl 5-0. Results: The average duration of surgery was 49.3 ± 4.8 minutes in the control group, 56 ± 5.5 minutes in the main group. During 1 year follow up in the main group there was no implant displacement and no another complication (0%). In the control group main complications developed in 12 patients (23.7%) (p < 0.05). The complication was dislocation and visible movement of implants in all 12 cases, and all patients were unsatisfied. Conclusion: Individual produced chin PEEP implants can be used to produce very nice aesthetic result with minimal complications and very high satisfaction rate.
