Virtual surgical planning in orthognathic surgery: A prospective evaluation of postoperative accuracy.

Objectives: The development of 3D computer-assisted technologies over the past years has led to vast improvements in orthognathic surgery. The aim of the present study was to evaluate differences in maxillary position between 3D virtual surgical planning (VSP) and surgical results.

Materials And Methods: We assessed data from 25 patients who underwent bimaxillary non-segmented orthognathic surgery with 3D VSP.

Outpatient orthognathic surgery: a prospective study of predictive factors for the length of hospital stays.

Objectives: Transitioning from non-outpatient orthognathic surgery to outpatient surgery is a new challenge, and it is essential to target the eligible population as precisely as possible. Several authors describe series of outpatient orthognathic surgery but do not include the reasons for their success or failure. The main aim of this study was to identify the factors significantly associated with "successful" outpatient orthognathic treatment.

Mandibular Titanium Miniplates Change the Biomechanical Behaviour of the Mandible in the Case of Facial Trauma: A Three-Dimensional Finite Element Analysis.

Our study aimed to compare the biomechanical behaviour of mandibles with or without titanium miniplates when subjected to an impact after bone healing using a finite element model (FEM) of the human mandible. We simulated mandibular trauma on an FEM of a human mandible carrying or not two parasymphyseal miniplates and applying a concentrated force of 2000 N to four different areas, including the insertion area, the area straddling the edge of the miniplates and the adjacent bone, at a distance from the miniplates on the symphysis, and on the basilar border of the mandible below the miniplates. Then, we compared the Von Mises stress distributions between the two models.

Photography in orthognathic surgery: A standardized protocol and storage legal implications.

Medical photography is an essential tool in orthognathic surgery to facilitate diagnosis, preoperative planning, and follow-up. Photographic documentation has clinical, research, teaching and legal applications. An accurate diagnostic approach and surgical planning of dentofacial deformity requires the ability to work with reproducible and measurable photographic images.

Botulinum toxin type A for the treatment of excessive gingival display - A systematic review.

Gummy smile has traditionally been treated with invasive or demanding surgical and orthodontic techniques. Several studies have shown that targeted injection of the upper lip elevator muscles with botulinum toxin is an effective treatment for this condition. However, no standardized injection protocol with reproducible results has yet been published.

Artificial intelligence for oral and maxillo-facial surgery: A narrative review.

Artificial Intelligence (AI) is a set of technologies that simulate human cognition in order to address a specific problem. The improvement in computing speed, the exponential production and the routine collection of data have led to the rapid development of AI in the health sector. In this review, we propose to provide surgeons with the essential technical elements to help them understand the possibilities offered by AI and to review the current applications of AI for oral and maxillofacial surgery (OMFS).
