Dental autotransplantation is a surgical technique aimed at treating tooth loss, whose success has been influenced by poor healing of the autotransplant. Numerous investigations have been conducted to optimize the process of scar tissue, emerging materials that promote healing significantly. Among these is the platelet-rich plasma (PRP), which is presumed to accelerate the regeneration and recovery time decreases tissue. The purpose of this study was to compare healing alveolar hard and soft tissue of two immature retained third molars, autotransplanted to the position of lower right first molar and lower left second molar, which was applied PRP. It was sixteen-years old female patient, who had molars with indication of extraction by deep caries. Clinical variables were evaluated: bleeding, mobility, presence of periodontal pockets and inflammation; and radiographic: presence of pathology apical, lamina dura , periodontal ligament space, loss of the bone, and newly formed root apical. Follow-up was six months with immediate postoperative controls, fifteen days, one month, three and six months. In both autotransplants were healing in the alveolar socket, but in the socket that received PRP was observed that was faster and with better clinical and radiographic features. Dental autotransplantation is considered as an effective treatment option which can be improved with the use of regenerative materials according to specific parameters for the technique.
