Genioplasty with surgical guide using 3D-printing technology: A systematic review

Abstract

Background: The purpose of this systematic review is to evaluate the current state of the art of making genioplasties using 3D printing technology. Material and Methods: A multi-database single-reviewer systematic review identified sixteen papers that fulfilled the selection criteria. There were mainly case series and case reports available (Level IV of the Oxford Evidence-based medicine scale); only two prospective study (Level III) evaluated this subject. These articles are analyzed in details and summarized in this review. Results: The realization of genioplasties with surgical guide using 3D-printing technology could improve predictability and accuracy. It protects anatomical structures in the environment of the surgery, reducing by this way the morbidity and providing safer results. The type of printer and material used as well as the sterilization techniques should be further developed by the authors. The use of open-access software should also be further explored to allow the use of these new technologies by the largest number of surgeons. Conclusions: Finally, prospective multi-center studies with larger samples should be performed to definitively conclude the benefits of this new technology and allow for its routine use. This article is the first systematic review on this topic.

Comparison of Changes in the Condylar Volume and Morphology in Skeletal Class III Deformities Undergoing Orthognathic Surgery Using a Customized versus Conventional Miniplate: A Retrospective Analysis

“…Surgical accuracy can be significantly improved using CAD/CAM techniques [ 22 ]. Most authors agree that these new systems provide an excellent level of accuracy in OGS that is generally higher than that obtained using classic methods [ 8 , 10 , 22 , 23 , 24 ]. Nevertheless, the quality of the surgical results is still determined by the individual surgeon’s skill in executing the surgical plan.…”

“…Nevertheless, the quality of the surgical results is still determined by the individual surgeon’s skill in executing the surgical plan. However, many studies have shown that clinicians can increase surgical safety, shorten the operative duration, and improve the predictability of the surgical results using patient-specific systems based on 3D technology [ 22 , 23 , 24 ]. Recently, 3D color mapping has enabled 3D visualization of the skeletal changes to the condyle after surgical manipulation of the jaw bones, and this technique can be applied to monitor positional changes of the condyle.…”

The accuracy and reliability of 3D printed aortic templates: a comprehensive three-dimensional analysis

“…The next stage of development and search for new applications for additive manufacturing technologies are 3D models used as surgical templates or guides (13)(14)(15). They are made based on computed tomography (CT) of a given patient, so they are patient-specific devices.…”
