The purpose of this study was to evaluate the clinical results of implants and milled bar supported edentulous maxillary obturators following the surgical ablation of maxillary tumors.
Seven patients with malignant tumors of the maxilla were studied. All patients underwent partial or total maxillectomy. Implants were installed in the remaining maxilla and milled bar supported obturators were fabricated. Masticatory efficiency, biting abilities, speech function, and changes in the marginal bone level around the implants were evaluated without the prostheses, with the previous prostheses, and with the implant-supported prostheses.
All implants were osseointegrated. All patients wore milled bar supported obturators and masticatory and speech functions markedly improved. There was no complication during the follow-up period.
These results suggest that a maxillary obturator supported by milled bar attachments is useful for oral rehabilitation in patients with resected edentulous maxilla.
本研究旨在评估上颌肿瘤手术切除后种植体及铣削杆支持的无牙上颌阻塞器的临床效果。
研究了7例上颌恶性肿瘤患者。所有患者均接受了部分或全上颌骨切除术。在剩余的上颌骨中植入种植体，并制作铣削杆支持的阻塞器。在未佩戴假体、佩戴先前假体以及佩戴种植体支持的假体的情况下，评估咀嚼效率、咬合力、语音功能以及种植体周围边缘骨水平的变化。
所有种植体均实现骨整合。所有患者均佩戴铣削杆支持的阻塞器，咀嚼和语音功能明显改善。随访期间无并发症发生。
这些结果表明，铣削杆附件支持的上颌阻塞器对无牙上颌骨切除患者的口腔修复是有用的。
