Three-dimensional printer-assisted reduction genioplasty; surgical guide fabrication

Abstract

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.

Radiographic Assessment Of Soft Tissue Changes In Advancement Genioplasty: Computer Guided Osteotomy Versus Peek Onlay Approach: A Randomized Clinical Trial

“…For instance, Berridge et al and Keyhan et al (32,33) developed a 3D-printed guide specifically for chin osteotomy, while Hsu et al and Costa et al (34,35) designed guides to realign the chin to its preplanned location. While others used both types of guides.…”

Guided Genioplasty: Comparison between Conventional Technique and Customized Guided Surgery

“…In general, the mandibular bone has a high density, and the bone volume at the mental level is large. However, if the anatomy of each case is not taken into account, it is possible to place screws that are longer than the bone width and cause injury to soft structures, with a potential risk of bleeding, especially the floor of the mouth and the mental area [15,16]. The use of polyamide as a material for the manufacture of the customized cutting guides also provides a small modulus of elasticity that enhances the positioning of the instrument at the surgical site and its subsequent adaptation [17,18].…”
