全上颌骨缺失后的功能恢复是颌面缺损修复中的一个重大难题．作者在患者两侧颧弓根部植入种植体，在其上设置有磁性固位体的环形支架，为上颌赝复体提供固位和支持，可有效地恢复患者的咀嚼和语言功能，容貌也得到显著改善。试验表明，全上颌大赝复体在口内的实际固位力可达到２９．４Ｎ，平均力达６０Ｎ．作者认为这种方法是目前全上颌骨缺失修复最有效的方式。
Functional recovery after total maxillary loss is a major challenge in maxillofacial defect repair. The author implants the implant at the zygomatic arch at both sides of the patient and has a ring-shaped stent on which a magnetic retainer is provided to provide retention and support for the maxillary prosthesis that can effectively recover the patient's chewing and speech function, Significantly improved. Experiments show that the maxillary large prosthesis in the mouth of the actual retention force can reach 29.4N, the average force of 60N. The authors believe that this method is the most effective way to repair the entire maxillary defect.
