3D Photogrammetry Versus Commercial Scanners for Accurate Repositioning of the Maxilla for Correction of the Dentofacial Deformity.
Dentofacial Deformities
About this trial
This is an interventional treatment trial for Dentofacial Deformities focused on measuring 3D Photogrammetry, Reverse Engineering, Orthognathic Surgery, Pre-bent Plates
Eligibility Criteria
Inclusion Criteria: Age range of 18-60 years. Patients requiring one-piece Le-Fort I osteotomy as part of their orthognathic surgery for the correction of dentofacial deformity. Patients should be free from any significant medical condition that could affect or hinder normal healing and predictable outcomes. Patients with no signs or symptoms of temporomandibular joint disorders. Patients who will be committed to the follow up period and agree to sign the informed consent. Exclusion Criteria: Patients requiring segmental Le-Fort I osteotomy. Patients with previous history of orthognathic surgery. Patients with cleft lip and palate. Patients with skeletal deformities owing to trauma or tumor resection. Patients with any intra-bony lesions or infections. Patients with temporomandibular joint disorders.

Maxillary segment repositioning by utilizing reverse engineering using the 3D photogrammetry.
Maxillary segment repositioning by utilizing reverse engineering using the commercial scanners.
The printed stereolithographic model with the adapted miniplates will be scanned using 3D photogrammetry technique and a specific software dedicated for image acquisition will be used. A guide will be designed on the reproduced virtual model. This guide will be used intraoperative as a locating and positioning guide for the maxilla and the plates.
• The printed stereolithographic model with the adapted miniplates will be scanned using the commercial scanners and imported for virtual designing of the positioning and locating guide that will be used intraoperative for positioning the maxilla.
