Soft tissue genioplasty: an innovative surgical technique for the correction of chin soft tissue abnormalities.

The chin is a major functional and aesthetic anatomical unit of the face. The correction of bony abnormalities is common in orthognathic surgery, but the management of the soft tissues is complex. This article describes a genioplasty technique focused on the soft tissue.

Current concepts in targeted therapies for benign tumors of the jaw - A review of the literature.

The aim of our study was to review current concepts in targeted therapies for benign tumors of the jaw. Benign odontogenic and maxillofacial bone tumors often require radical surgery, with consequent morbidity that impacts patients' postsurgical quality of life. Currently, targeted therapies and novel nonsurgical therapeutics are being explored for management of non-resectable tumors, with the aim of avoiding surgery or minimizing surgical scope.

Idiopathic dilatation of the submandibular gland duct.

Lithiasis and stenosis may cause salivary duct dilatation due to the increased pressure in the duct upstream of the obstruction. Idiopathic dilatations, also called megaducts, with no associated increase in pressure, have only been described in the parotid gland. The aim of this study was to describe the characteristics of submandibular duct dilatation unrelated to lithiasis, stenosis, or an imperforate duct, to report the existence of submandibular megaducts.

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.

Prosthetic rehabilitation of a completely edentulous maxilla with a sectioned implant-supported screw-retained prosthesis in a multiamputee patient with microstomia: A clinical report.

Providing fixed implant-supported prostheses for edentulous patients with microstomia or limited mouth opening is challenging. The clinical treatment of a patient who was a multiple amputee with microstomia and a complete loss of lips elasticity is described. A custom half-sectioned prosthesis was fabricated to resolve numerous difficulties.
