THE IMPACT OF IN-HOUSE SURGICAL GUIDES ON GENIOPLASTY PRECISION

Objective: The aspect, volume, shape, and projection of the chin contribute to a “well-balanced and harmonious” face, and good projection influences psychosocial well-being, playing a fundamental role in facial aesthetics. The aim of this paper is to discuss the importance of using surgical guides in genioplasty. Case Series: Two patients underwent bimaxillary orthognathic surgery with genioplasty using 3D-printed guides were reported. Case 1 involved posterior impaction and 2mm advancement genioplasty. Case 2 addressed chin rotation, posterior impaction, and lowering without advancement. The chin’s form and projection contribute to facial harmony. Conclusion: Computer-assisted surgical simulation allows precise guide creation, making genioplasty safer and minimally invasive. Guides reduce complications and offer cost-effective benefits over traditional methods. Genioplasty with in-house 3D-printed guides shows promise in improving predictability, precision, and safety. Further research on printers, materials, sterilization, and open-access software is needed.
