A retrospective study was conducted to explore the application of digital model surgery in the treatment of dento-maxillofacial deformities. Fifteen patients with dento-maxillofacial deformities were enrolled in this study. A digital craniomaxillofacial-dentition model was established by combining three-dimensional (3D) computed tomography (CT) and laser-scanned dentition models. Based on this ...

In corrective osteotomy of the radius, detailed preoperative planning is essential to optimising functional outcome. However, complex malunions are not completely addressed with conventional preoperative planning. Computer-assisted preoperative planning may optimise the results of corrective osteotomy of the radius. We analysed the pre- and postoperative radiological result of computer-assisted...

BACKGROUND Old pelvis fractures are among the most challenging fractures to treat because of their complex anatomy, difficult-to-access surgical sites, and the relatively low incidence of such cases. Proper evaluation and surgical planning are necessary to achieve the pelvic ring symmetry and stable fixation of the fracture. The goal of this study was to assess the use of three-dimensional (3D)...

Multicatheter brachytherapy can be applied as a monotherapy or in combination with external beam radiotherapy as an adjuvant treatment for soft tissue sarcoma. Successful application of brachytherapy in the treatment of soft tissue sarcoma requires implementation of multiple imaging modalities during preoperative and postoperative planning. Preoperative imaging is essential in planning local th...

background: liver dysfunction during on-pump coronary artery bypass graft surgery (cabg) is a rare complication but is associated with significant morbidity and mortality. the ability to identify high-risk patients may be helpful in planning appropriate management strategies. we aimed to evaluate the factors influencing liver function tests during on-pump cabg. methods: in 146 patients schedule...

Background: Ameloblastoma is the most common benign epithelial odontogenic tumor with malignant potential and usually located in jaw. It constitutes about 1-3% of all tumors cysts jaws. This entity has a very high recurrence rate over 50% even after wide excision. Preoperative diagnosis ameloblastoma can be made by fine-needle aspiration biopsy (FNAB) which used as guide for surgical planning. ...

This article reviews the various anatomical facts significant for preoperative planning of implant procedures in the mandible and the maxilla. This planning includes the precise evaluation of distinct anatomical factors, such as the position of the mandibular canal, the maxillary sinus, the width of the cortical plates, the existing bone density , appropriate implant selection and planning the ...

Background and Objectives: 3D visualization technology provides a more intuitive visual virtual reality surgical presentation for preoperative simulation planning, inhand operation accurate postoperative assessment in procedures, but there is lack of evidence to support whether this advantageous planning giant goiter. The aim study was investigate the value

Introduction For preoperative surgical planning, a simulation system has to support realistic cuts, which are normally smooth and curved. Since biological soft tissue is deformed with large displacement on an incision, the soft tissue model should support nonlinearity. Although the focus of surgical planning is accuracy, good acceptance by the surgeons can only be achieved with good response ti...
