The Use of Bone-borne Guides in Orthognathic Surgery Cases

Status Completed

Clinical Trial Summary

The present study was conducted to evaluate a new design of the intermediate stent that is used in orthognathic surgery cases requiring Le Fort I osteotomy. The new design relied on referencing the maxillary segment to the zygomatic buttress. The study was carried out as a randomized controlled clinical trial in which 16 patients were enrolled according to the inclusion and exclusion criteria. In control group (n=8) conventional interocclusal splint was used and in study group (n=8) the proposed intermediate stent was used.

Clinical Trial Description

Background: Dentofacial deformities have many negative consequences in the form and function of head and neck region. This includes breathing, swallowing, speech and temporomandibular disorders. It is estimated that in about 19% of orthodontic patients, orthognathic surgery is required along with the orthodontic procedure. The introduction of CAD/CAM technology in orthognathic surgery planning has facilitated the procedure and allowed for more predicted results. Aim of this study: The aim of the present study is to propose a new design of the intermediate stent that relates the mobilized maxilla to a fixed anatomical landmark in the skull which would allow for more accurate positioning of the maxilla during orthognathic surgery. Materials and methods: This study was conducted on sixteen patients who have been undergone Le Fort I osteotomy procedure. Eight of them (group A) were treated via a conventional stent while the other eight patients (group B) via a CAD/CAM bone-borne stent. Postoperative patient evaluation was performed by comparing the predicted maxillary position to the resultant position postoperatively. This was done via 3D reconstruction CT scans. ;
