Cancer resection is the most common cause of acquired palatal defects, whereas cleft palate is the main cause of congenital defects. Palatal defect can be repaired by reconstructive surgery and/or a dental prosthesis. We present prosthodontic rehabilitation of two maxillary edentulous patients, one with a surgically induced palatal defect and the other with congenital cleft palate. In case 1, an 86-year-old man underwent surgical removal of soft-palate squamous cell carcinoma. The acquired palatal defect was repaired by a maxillary complete denture with a posteriorly extended speech bulb. The final prostheses provided good chewing and speech functions. In case 2, a congenital cleft palate in a 65-year-old man was repaired by a maxillary complete denture with superior extension of the obturator, which was designed to improve retention and stability of the upper single denture. He was satisfied with the upper denture after prosthesis placement. Conventional maxillary complete denture with a posteriorly extended speech bulb or modified obturator provides a good chance to restore oral functions in patients with palatal defects. The patients' skill and previous experience of denture wearing might have been important in their successful treatment. However, different patients present with unique problems and need to be treated individually.
癌症切除术是获得性腭部缺损的最常见原因，而腭裂是先天性缺损的主要原因。腭部缺损可以通过重建手术和/或义齿修复来修复。我们介绍了两位上颌无牙患者的义齿修复，一位患者存在手术引起的腭部缺损，另一位患者存在先天性腭裂。在病例 1 中，一位 86 岁的男性因软腭鳞状细胞癌接受了手术切除。采用后部扩展语音球的上颌全口义齿修复获得性腭部缺损。最终的义齿提供了良好的咀嚼和言语功能。在病例 2 中，一位 65 岁的男性因先天性腭裂，采用上腭延伸的修复体来修复上颌完全义齿，该修复体旨在改善上颌单颗义齿的固位和稳定性。在义齿放置后，他对上颌义齿感到满意。后部扩展语音球或改良的修复体的传统上颌全口义齿为腭部缺损患者恢复口腔功能提供了很好的机会。患者戴义齿的技巧和以往经验可能对他们的成功治疗很重要。然而，不同的患者存在独特的问题，需要个体化治疗。
