Modification of Sagittal Split Osteotomy in Class II Asymmetry: Optimizing Bone Contact between Proximal and Distal Segments.

Background: Computer-assisted surgical simulation (CASS) allows more precise orthognathic surgery. However, few studies have evaluated associations between CASS-designed bilateral sagittal split osteotomy (SSO) and bone contact surface in class II mandibular asymmetry. This study aims to evaluate the effects of using computer-assisted simulation and design modification of SSO to improve bony contact in skeletal class II asymmetry.

Simultaneous Surgical Correction of Skeletal Class III Dentofacial Deformity During Acute Management of Facial Fractures: Patient Selection and Surgical Technique.

Background: Mandibular prognathism is a common dentofacial deformity in Asia. Treatment of such condition may vary from orthodontic camouflage to surgical orthodontics with orthognathic surgery depending on the severity of the condition. Because of the prominent position of the mandible, fractures involving different locations of the mandible commonly occur in maxillofacial trauma.

Systematic review of the surgery-first approach in orthognathic surgery.

The surgery-first approach in orthognathic surgery has recently created a broader interest in completely eliminating time-consuming preoperative orthodontic treatment. Available evidence on the surgery-first approach should be appraised to support its use in orthognathic surgery. A MEDLINE search using the keywords "surgery first" and "orthognathic surgery" was conducted to select studies using the surgery-first approach.

Biomechanical evaluation of a new MatrixMandible plating system on cadaver mandibles.

Purpose: Current mandibular plating systems contain a wide range of plates and screws needed for the treatment of mandibular reconstruction and mandibular fractures. The authors' hypothesis was that a single diameter screw could be used in all applications in a plating system. Therefore, the purpose of this study was to test if the 2.

Accuracy of a computer-aided surgical simulation protocol for orthognathic surgery: a prospective multicenter study.

Purpose: The purpose of this prospective multicenter study was to assess the accuracy of a computer-aided surgical simulation (CASS) protocol for orthognathic surgery.

Materials And Methods: The accuracy of the CASS protocol was assessed by comparing planned outcomes with postoperative outcomes of 65 consecutive patients enrolled from 3 centers. Computer-generated surgical splints were used for all patients.

Comparison of progressive cephalometric changes and postsurgical stability of skeletal Class III correction with and without presurgical orthodontic treatment.

Purpose: This study compares 1) progressive dental and skeletal changes, 2) postsurgical stability, and 3) treatment efficacy of patients with skeletal Class III correction with and without presurgical orthodontic treatment.

Patients And Methods: The study includes 53 patients who underwent orthognathic surgery (OGS) to correct skeletal Class III malocclusion. The patient grouping is based on presurgical orthodontics: surgical-first (SF) approach (n = 18) and modified-conventional (MC) approach (n = 35).

Dermatology of the patient with HIV.

Cutaneous diseases occur in most people infected with human immunodeficiency virus (HIV) and at a higher rate than people not infected with HIV. Common HIV-related rashes and rashes made unusual by HIV infection are reviewed.
