Study summary

Combined application of surgery planning software and rapid prototyping technology and preshaped titanium plates can effectively promote the accuracy of the diagnosis and treatment of bilateral maxillofacial post traumatic deformities, reduce operation time and improve surgical effect.

Read the detailed description

All patients underwent preoperative CT scan. Firstly, SurgiCase were used to analyze CT data and design preliminary surgery plans. Secondly, three-dimensions resin skull models were produced by rapid prototyping technology. Model surgeries were performed to determine the location, reduction direction and shift distance of osteotomy. Based on the surgical simulation, the preliminary surgery plans were validated and optimized. Then, the titanium plates and mesh were preshaped on the models. Finally, according to the final surgery plans the operations were performed. The operation time, therapeutic effects and complications were observed. The follow-up periods were 1-12 months.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 12, 2013, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
