Official Title: Three-Dimensional Printing of Patient-Specific Titanium Plates in Jaw Surgery: An Open-Label, Prospective Pilot Clinical Study
Brief Summary:
Medical titanium plates are routinely used in fixing mobilized bone segments in jaw surgeries. Generally these plates are commercialized with standard construction specifications. Thus they should be repeatedly bended and arched to match the contour of anchored jaw bones before located in place and fastened by screws. To prevent stress fatigue induced by plate bending and improve structural design, we utilized the three-dimensional printing technique and developed a new production procedure in fabricating customized titanium plates according to each patient's specific skeletal contours and dimensions derived from medical imaging data. In general, the three-dimensional printing of customized implants are expected to facilitate surgical operation, reduce application duration and improve precise restoration.
Up until now, the application of three-dimensional printing of titanium fixation plates in jaw surgery has been available only at two centers globally. The published preliminary work have proved the prospect of customized titanium plates in promoting mandibular reconstruction surgery and upper maxilla orthognathic surgery though their printed titanium plates looked rather bulky and the sample sizes were small and there is still lack of qualified randomized controlled trials between the printed and the conventional titanium plates. To better benefit from the burgeoning use of three-dimensional printing in health care, it is imperative to conduct a feasibility study in exploring the application of three-dimensional printing of titanium fixation plates in jaw surgery based on our patients.
The aim of the study is to conduct a case series study focusing on the feasibility and safety of applying three-dimensional printed titanium plates in jaw reconstruction surgery and orthognathic surgery. The outcome measures include the su
