“…Among these devices, those used in genioplasty required more accurate mandibular dental data, and were more complex to design, compared to the method that we now describe [ 4 , 8 ]. The usefulness of STL guides may also depend on the surgeons’ expertise, and the type of genioplasty, such as zigzag genioplasty [ 10 – 12 ].…”

BackgroundThe present study introduces the design and fabrication of a simple surgical guide with which to perform genioplasty.MethodsA three-dimensional reconstruction of the patient’s cranio-maxilla region was built, with a dentofacial skeletal model, then derived from CT DICOM data. A surgical simulation was performed on the maxilla and mandible, using three-dimensional cephalometry. We then simulated a full genioplasty, in silico, using the three-dimensional (3D) model of the mandible, according to the final surgical treatment plan. The simulation allowed us to design a surgical guide for genioplasty, which was then computer-rendered and 3D-printed. The manufactured surgical device was ultimately used in an actual genioplasty to guide the osteotomy and to move the cut bone segment to the intended location.ResultsWe successfully performed the osteotomy, as planned during a genioplasty, using the computer-aided design and computer-aided manufacturing (CAD/CAM) surgical guide that we initially designed and tested using simulated surgery.ConclusionsThe surgical guide that we developed proved to be a simple and practical tool with which to assist the surgeon in accurately cutting and removing bone segments, during a genioplasty surgery, as preoperatively planned during 3D surgical simulations.

“…After fabricating 3D model of the jaw and radiographic evaluations on panoramic and lateral cephalometric radiographs, the amount of reduction in different aspects and appropriate techniques are determined. [256] According to data obtained from analysis of X-rays, designed osteotomy lines are drawn on 3D model. Next, a surgical guide is manufactured extending to areas beyond the osteotomy lines using transparent acrylic resin and carefully constructed to adapt to the anatomy of the bone [Figure 1].…”

Genioplasty is a common operation to enhance function and appearance of the chin, the most prominent part of the lower third of the face, which has major impact on character impressions and facial beauty. However, since transference of preconfigured accurate treatment plans to patients during operation is difficult, sometimes it can be challenging, especially for inexperienced surgeons. This article represents a simplified technique to perform reduction genioplasty by utilizing a customized genioplasty guide manufactured with three-dimensional printing technology. This approach is helpful to achieve more precise and safer outcomes with fewer complications.

“…[1] another techniques such as horizontal T osteotomy were also described but is not used widely( fig.2). [10,46]In 2013 we described [1,47] a novel technique to reduce the prominent chin 3-dimentionally( fig.3). This new genioplasty (Zigzag genioplasty) makes it possible to decrease the vertical and transverse dimension of the chin alone or simultaneously, symmetrically or asymmetrically.…”

“…Furthermore, this design preserves the suprahyoid muscle attachmentsand the most important anatomic portion of symphysis area; narrowing the wide chin by this technique provides an esthetic and natural facial look. [1,47] Figure 3. Zigzag osteotomy design is based on the displacement of 2 bone fragments on the slopes of an inclined plane with a superior-medial direction.…”
