A new tool for cast surgery in orthognathic treatment planning: SEVA (articulated system for visual evaluation)

Purpose: To describe a new tool to improve cast surgery and splint confection, how to use it and demonstrate it’s clinical application.

Materials and methods: In this trial the SEVA tool was used for planning 5 (five) orthognathic surgery cases. Presurgical and postsurgical vertical, transversal and sagital distances were measured.

Results: Of the 5 cases was obtained an error average of 0.38 mm (millimeters) for vertical movement; 0.15 mm for sagital movement and 0.13 mm for transversal movement.

Conclusion: The SEVA demonstrated to be a safe, precise and truthful tool. It saved time and work; permitted a three dimensional cast movement; helped to predict inferior jaw autorotation and it was also useful to reproduce the initial position.

Conflict of interest: None declared.
