Since orders and disorders in this very important region of our body are significantly measured in any case, operations in order to solve. These problems are quite common.Movement restrictions, pain and swelling are considered as negative consequences of this category of surgery.Although the prevalence of the consequences and probability of benefits of low level LASER therapy as a useful treatment in order to lessen or remove them, there has been not enough researchs in this regard yet and this is why we are going to deal with it in this article.<br /> <strong>Materials and Methods:</strong> In the current type of survey was experimental and far sighted. We had control group and the patients were selected by chance. Samples were among the patients who were suffering from prognatism and were operated almost two weeks before getting samples. <br /> <strong>Results:</strong>  36 patients [in two groups each with equal humbers of control and treat] who were suffering from prognatism and were operated to be reconstructed were treated with LLLT for 10 sessions. ontrolled variables were Intensity of pain, restrictions of movements and swelling. Shapirovilk and also coupled T and individual T were used to evaluate the results. Significative differences were observed between two groups of patients considering pain intensity,swelling and movement restrictions in beneath jaw.<br /> <strong>Conclusion:</strong> According to the results applying of LLLT may lead us to lessen the negative consefuences of jaw operated patients consisting: Pain, swelling and movement restrictions. <strong>Background and Aims: </strong>Tempromandibular joint is considered as one of the most important joints in our body.
