Facial Soft Tissue Changes after Maxillary Impaction and Mandibular Advancement in High Angle Class II Cases
The aim of this study was to determine the vertical and anteroposterior alterations in the soft, the dental and the skeletal tissues associated with the facial profile after Le Fort I maxillary impaction in conjunction with sagittal split osteotomy for mandibular advancement performed in patients with a high angle Class II skeletal deformity.The study population consists of 21 patients (11 fema...
متن کاملDevelopment of a Three-Dimensional Hand Model Using Three-Dimensional Stereophotogrammetry: Assessment of Image Reproducibility
PURPOSE Using three-dimensional (3D) stereophotogrammetry precise images and reconstructions of the human body can be produced. Over the last few years, this technique is mainly being developed in the field of maxillofacial reconstructive surgery, creating fusion images with computed tomography (CT) data for precise planning and prediction of treatment outcome. Though, in hand surgery 3D stereo...
متن کاملThree-dimensional assessment of mandibular advancement 1 year after surgery.
INTRODUCTION This prospective observational study evaluated changes in the 3-dimensional position and remodeling of the mandibular rami, condyles, and chin at splint removal and 1 year after mandibular advancement surgery. METHODS Presurgery, splint removal (4-6 weeks postsurgery), and 1-year postsurgery cone-beam computed tomography scans of 27 subjects were used. Superimposition on the cran...
متن کاملThree-dimensional assessment of maxillary changes associated with bone anchored maxillary protraction.
INTRODUCTION Bone-anchored maxillary protraction has been shown to be an effective treatment modality for the correction of Class III malocclusions. The purpose of this study was to evaluate 3-dimensional changes in the maxilla, the surrounding hard and soft tissues, and the circummaxillary sutures after bone-anchored maxillary protraction treatment. METHODS Twenty-five consecutive skeletal C...
متن کاملThree-Dimensional Analysis of Scoliosis Surgery Using Stereophotogrammetry
Scoliosis is a deformity characterized by coronal, sagittal and axial rotation of the spine. Surgical instrumentation (metal pins and rods) and eventual fusion of the spine are required in severe cases. Assessment of the deformity requires enough accuracy to allow proactive planning of individual interventions or implant designs. Conventional 2-D radiography and even 3-D CT scanning do not prov...
