Plain English summary of protocol

Background and study aims
Jaw surgeries commonly use a titanium alloy for bone fixation for many characteristics such as its light weight, high strength, corrosion resistance and good biocompatibility. The most commonly used plates for bone fixation are commercially available and are produced and casted according to the fixed shape of the mold, but the irregular shapes of jaw bone surfaces make these commercially available plates unable to completely fit to the contour of different bone surfaces and need bending to get an appropriate approximation between the bone parts. Plate bending wastes operation time, increases the operation risk and sheds off the protective surface of the titanium plate. Therefore, the construction of 3D-printed patient personalized titanium plates will overcome such problems in bone fixation. The aim of this study is to assess using a 3D-printed patient personalized titanium plate in jaw surgery.

Who can participate?
Patients aged 18-45 years with dentofacial (teeth/face) deformities requiring jaw surgery

What does the study involve?
The patients are randomly divided into the 3D printed personalized titanium plate group and the commercial titanium plate group. The follow-up for the treatment is 6 months after the jaw correction surgery and at the end of the sixth month the patients will be admitted for the removal of the titanium plates.

What are the possible benefits and risks of participating?
There is evidence that 3D-printed personalized titanium plates can improve the accuracy of jaw surgery, reduces the operation time and minimizes risks during the operation. The participants' condition may or may not improve moreover or there may be the following risks and discomfort. Although the titanium alloy material in this study has been tested in animals to ensure the safety of the product before its use in a clinical trial, uncertainty still exists regarding its clinical effects. Risks associated with the surgery include swelling, general rejection, local infection and inflammation, and wound dehiscence (separation of the edges of a surgical wound).

Scientific titleA prospective, multicenter, randomized, clinical controlled trial of using a three-dimensional printed patient personalized titanium plate in orthognathic surgery
Study objectivesThis study is designed to compare the effect of using a 3D printed personalized titanium plate and commercially available titanium plates in orthognathic surgery on the operation time and the accuracy of post-operative bone positioning.
Ethics approval(s)Approved 24/06/2020, Medical Ethics Committee, West China Hospital of stomatology, Sichuan University (Hospital Management Office, West China Medical Center, Building 1, West China East Campus, no. 28 South Telecom Street, Wuhou District, Chengdu, China; +86 (0)28-85503401; yxglc@scu.edu.cn), ref: not provided
Health condition(s) or problem(s) studiedManagement of dentofacial deformities through an orthognathic surgical intervention
InterventionA prospective, randomized multi-center clinical trial study planned to compare the accuracy of bone positioning following orthognathic surgery between 3D printed personalized titanium plates patient group and traditionally available titanium plates. The patients are randomly divided into the 3D printed personalized titanium plate group and the commercial titanium plate group. This study could not be blinded to surgeons, but the participants and evaluators are blinded. The follow-up for the treatment is 6 months after the jaw correction surgery and at the end of the sixth month the patients will be admitted for the removal of the titanium plates.
