Aloplastic materials are frequently used in oral and maxillofacial surgery for different purposes such as sinus lifting, and fillings with cosmetic goals. Among these biomaterials the methylmethacrylate has been routinely used for decades in maxillofacial surgery, orthopedics surgery, and neurosurgery. It presents biocompatibility, good resistance, no resorption, low cost, ease of handling, and is well tolerated in facial fillings. This article aims to present a new technique to fill the perinasal region. Patients with class III dentofacial deformities, showing mandibular excess associated with perinasal deficiency were treated with mandibular setback and perinasal filling with methylmethacrylate (Antibiotic Simplex). After surgery, adequate filling, and smoothernasolabial sulcus were achieved, with no infections or relapse after a minimum post operative of 6 months.
