The use of polylatic implants for orthognathic surgery has growing in the beginning of the century. The major advantages of this use consist on the fact that there is no residual implant and the patient acceptance on this material. The disadvantages include the cost and the handling. Herein, we show the initial experience in our service using resorbable plates and screws for maxillary fixation in maxillary advancement in 21 cases. We observed the need of maxilo-mandibular fixation (MMF) in the immediate post-operative time, and the stability in the immediate post-operative time, 1 month and 3 months after surgery. The stability was objectively evaluated observing the occlusion in the post-operative time and subjectively, the maxillary movement during palpation and mastication. We observe 2 (9.5%) cases of maxillary instability that need MMF in the immediate pos-operative. The first case we observed great maxillary movement. We opted for 15 days of MMF. The second case we observe maxillary retrusion, put in MMF for 10 days. Both cases have a good follow-up in 30 and 90 days. Disadvantages cited are not major problems in choosing the resorbable plates for maxillary fixation. The resorbable plates and screws is a good choice for maxillary fixation.
