3D Photogrammetry Versus Commercial Scanners for Accurate Repositioning of the Maxilla for Correction of the Dentofacial Deformity.

Egypt24 participantsStarted 2023-01-09

Plain-language 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?

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
