“…In cases of multiple unsuccessful surgical attempts, high risk of anesthetic complications because of the patient's health condition, or large cleft dimensions hindering grafting techniques, a palatal obturator composed of acrylic resin is indicated for adequate defect occlusion (Silva, Magalhães, Oliveira, Coelho, & Saldanha, 2009). Atallah et al (2013) and Sousa, Sampaio, Evangelista and Cunha (2016) applied self-cure acrylic resin in the plastic phase directly above the defect and obtained favorable results, with resolution of clinical signs. The advantage of selfcure acrylic resins is the complete occlusion of the defect, filling all irregularities in the oral cavity; however, the exothermic phase of the resin can cause thermal damage to the mucosa, leading to necrosis of the nasal and oral cavities.…”
