Systemic lupus erythematosus (SLE) is a chronic inflammation that involves the nervous system, mucous membranes, and other organs. Avascular bone necrosis (AVN) is a symptom that appears in people with SLE. Maxillectomy is performed on the maxillary bone affected with AVN. The postmaxillectomy gap closure was performed using an intraoral maxillofacial prosthesis, namely an obturator. This case report was aimed to examine the prosthetic rehabilitation using Acrylic resin definitive obturator prosthesis in SLE patients post-maxillectomy. Case report: A 21-years-old woman came to Dr Sardjito Oral Clinic with complaints of bad breath, palatogingival loss, and loose maxillary teeth. The patients was diagnosed with SLE for more than one year prior. The intraoral examination result showed that apart from the palatal mucosa lesions, there was also found necrosis of the palate bone, loss of teeth 14, 15, 16, and 25, and grade 3 loose of all of the remaining maxillary teeth. The patient was treated with Myfortic® (2 x 180 mg/day) and Fluconazole® (1 x 150 mg/day), then referred to the Oral Surgery Clinic for maxillectomy, followed the fabrication of obturator prostheses by the prosthodontist team. The patient was assigned a postoperative obturator to close the palate gap after maxillectomy. An imprint was carried out using an irreversible hydrocolloid material before surgery for the manufacture of a post-surgical obturator. The obturator insertion shows that the palate gap was tightly closed by an acrylic plate. Retention was obtained using the stainless wire on titanium wire mesh instead of the maxillary bone—the patients presented no complaints during control and had adequate ingestion. Three months after wearing a postoperative obturator, the acrylic resin definitive obturator prosthesis was then installed. Clinical examination showed reduced nasal sound, and better aesthetical and mastication aspect. Conclusion: Acrylic resin definitive obturator prosthesis in post-maxillectomy SLE patients can restore aesthetic function, reduce nasal sound (restore speech function), restore swallowing and mastication function.
