Throughout history, the development of science has collaborated with the progress of new therapies based on society's demands to maintain public health and its physical integrity. Technological development in basic areas (i.e. general anesthesia and biomaterials) helped the progress of Dental Science. For example, the Oral and Maxillofacial Surgery (OMS) was able to develop novel and more advanced surgical techniques bringing clinical benefits that did not exist earlier. Brazilian research groups have played an important role in the development of new alternatives to surpass these therapeutic limitations. For instance, some cases of tooth impaction, which could only be treated by dental extraction, are currently resolved through alternative surgical techniques such as Apicotomy and Double Traction, preventing tooth loss. Likewise, patients with temporomandibular joint (TMJ) ankylosis can be favored by a surgical treatment called Puricelli Biconvex Arthroplasty. This procedure has minimally invasive osteotomy, uses a financial affordable alloplastic material, and maintains joint stability. Finally, Brazilian techniques have contributed to improve other well-established surgical treatments. This is the case of the Puricelli Osteotomy, which provides a more stable position for the mandible during orthognathic surgery. Therefore, the aim of the present paper is to summarize and discuss the scientific and methodological contributions of these surgical techniques (developed by the Department of Surgery and Orthopedic of Universidade Federal do Rio Grande do Sul) and their indications.
