چکیده

In this paper we present in depth one of the preprocessing steps of our software system for the simulation of soft tissue behaviour and biomechanical processes. The entire system can be used by surgeons for preoperative planning and prediction of postoperative results. The software creates a pipeline to automatically construct meshed datasets for finite element modelling from presegmented patient data. In further parts of the system resulting deformations of soft tissue from surgical interventions and motion of bones are computed for visual and haptic display.

Soft Tissue Prediction in Computer Assisted Maxillofacial Surgery Planning A Quantitative Evaluation of Histomechanical Modeling using Pre- and Postoperative CT-Data

The aim of our work is to provide maxillofacial surgeons with a computer assisted 3D planning environment for complex bone relocations, facilitating a preoperative assessment of functional as well as esthetic rehabilitation. On this account we are developing an interactive simulation and visualization system and try to establish a robust modeling framework based on a biomechanical soft tissue m...

Evaluating soft tissue simulation in maxillofacial surgery using preoperative and postoperative CT scans

One of the most important issue in soft tissue modeling is to assess the quality of the simulations. A validation protocol is presented based on two CT scans of the patient acquired before and after craniomaxillofacial surgery. The actual bone repositioning realized during the intervention are accurately measured and reproduced. An evaluation of the soft tissue deformation is then computed usin...

Review of Nasal Soft Tissue alterations in Class III Malocclusion patients following Lefort I Osteotomy

Abstract Background and Aim:  The primary aim of orthognathic surgery is to improve the aesthetic parameters of the face and dentition and to transform it into an acceptable clinical standard, which is often associated with the secondary aim of improving occlusal function. The most common treatment option for maxillofacial abnormalities in Class III malocclusion patients is bimaxillary surgery,...
