Is Beauty a Matter of Volume Distribution? Proposal of a New Aesthetic Three-Dimensional Guide in Orthognathic Surgery.

Background: Orthognathic surgery is a multidisciplinary surgery in which the aesthetic results have become increasingly important, and consequently, also the predictability of the surgical outcomes. In this paper, we analyzed the volumetric distribution of the lower two-thirds of the face, in patients operated by orthognathic surgery and selected for their attractiveness. Our goal was to analyze the aesthetic volumetric distribution for gender and to propose our operating philosophy, that a normative distribution of facial volumes could be used like a new 3D aesthetic guide in orthognathic planning.

Three-dimensional cephalometric outcome predictability of virtual orthodontic-surgical planning in surgery-first approach.

Objectives: The aim of this study is to introduce a novel 3D cephalometric analysis (3DCA) and to validate its use in evaluating the reproducibility of virtual orthodontic-surgical planning (VOSP) in surgery-first approach (SF) comparing VOSP and post-operative outcome (PostOp).

Methods: The cohort of nineteen patients underwent bimaxillary orthognathic surgery following the VOSP designed in SimPlant O&O software by processing cone-beam computed tomography (CBCT) scans and intraoral digital scanning of the dental arches. Said records were re-acquired once the post-operative orthodontic treatment was completed.

Virtual Orthodontic Surgical Planning to Improve the Accuracy of the Surgery-First Approach: A Prospective Evaluation.

Purpose: We developed an innovative computer-assisted method to increase the accuracy of the surgery-first (SF) approach by linking the virtual orthodontic planning (VOP) with the virtual surgical planning (VSP).

Materials And Methods: Fifteen consecutive patients were enrolled from 2013 to 2015. All 15 patients had initially undergone cone-beam computed tomography (CBCT; 15 × 15 field-of-view) and intraoral digital scanning of the dental arches.

Maxillary expansion and stability in the orthodontic-surgical treatment of skeletal anterior open bites.

Objectives: Evaluation of the surgical/orthodontic treatment's stability using rigid internal fixation.

Methods And Materials: Seventeen patients presenting an anterior skeletal openbite, analyzed retrospectively to evaluate stability of surgical-orthodontic treatment using rigid internal fixation: mini plates and screws for maxillary fixation and bicortical screws for the mandible. The surgical procedures were Le Fort I osteotomy and bilateral sagittal split mandibular osteotomy.
