1,2,9 Using these tools, the user can cut bone and reposition in real time since the simulation system recalculates the soft tissues of the skin on top of the new bone structure. Refined cutting tools permit anatomically correct osteotomies of the maxilla or mandible. Specific measurements of parameters such as surgical movement can be calculated. The virtual simulation can

then be used to preplan Inhibitors,research,lifescience,medical surgical procedures such as the shape and size of fixation plates or other implants. In addition, the placement of the virtual model on the web permits many individuals in different locations to view and discuss the case and treatment plan (Figure 8).1,2,9 Figure 8 The same patient depicted in Figure 6, post-surgery imaging. CONCLUSIONS

Inhibitors,research,lifescience,medical Advancements in computer imaging have revolutionized the treatment of dentofacial deformities and, specifically, orthognathic surgery. Prototyping, computer imaging, and simulation can provide significant benefits for both the professional and the patient. Greater precision and accuracy in diagnosis and surgery can be obtained by means of virtual training. The surgeon’s performance can Inhibitors,research,lifescience,medical improve using these systems for training, and it is risk-free. All of this increases the patient’s safety and improves the outcome. Recent technical advances have made computer imaging more realistic and user friendly and have lowered the cost. The ability to make these systems web-based adds another facet by increasing availability. Team members, even though they may be distant from one another, can simultaneously evaluate treatment options in real time. The continuous changes in Inhibitors,research,lifescience,medical this field will be associated with the ever-increasing adoption of computer imaging and simulation in medicine and surgery, forever changing the practice of medicine.

Heart failure is a leading cause of morbidity and mortality with a prevalence that is rising throughout the world.1 It is estimated, for example, that in Europe around 10 million people are suffering from this disease. Despite some progress in medical treatment within the last 10 years, morbidity and mortality of congestive heart failure are still high: 70%–80% of patients suffering from heart failure will die within the next 8 years.2 The reasons for the increase in see more incidence include the aging population and the increase in the cardiovascular risk factors obesity, diabetes, and hypertension.
