Summary

Current advances in the three-dimensional virtual surgical planning (3D-VSP) of the orthognathic surgery have brought newer insights, enormous benefits and have become an indispensable aid for diagnosis, treatment planning and outcome assessment especially in the management of dentofacial deformities.

The extent to which the planned surgical outcome could be achieved is dependent on the surgeon's ability to accurately transfer the planned movements to the real surgical field. Accurate repositioning of the maxilla after Le-fort I osteotomy is of utmost importance for an esthetic and functional purposes.

The goal of this interventional study is to compare the 3D photogrammetry technique versus the commercial scanners for accurate repositioning of maxillary segment after le-fort I osteotomy using the reverse engineering technology.

The main question it aims to answer; Is the utilization of the 3D Photogrammetry technique affect the accuracy of maxillary segment repositioning after le-fort I osteotomy compared with the commercial scanners?

Conditions

  • Dentofacial Deformities

Interventions

PROCEDURE

Maxillary Segment Repositioning

* Le-Fort I osteotomy will be made using the cutting guide. * Mobilization of the maxilla will be done. * The osteotomized segment will be positioned using the positioning guide that will be fabricated utilizing the reverse engineering technology using 3D photogrammetry technique. * While the guide in place, the plates will be fixed into their intended position. * After fixation of the plates, the guide will be removed.
