In order to evaluate the applying effect of MDIC implant-magnetic attachments on oral and maxillofacial prostheses, 38 patients, whose oral and maxillofacial defects had been restored with implant-magnetic attachments prostheses, were followed up for 1-4 years. The effects were evaluated by the measurement of the retentive force of the prostheses, X-ray and clinical examination. The results show: the successful rate of the restoration was 94.7%; two sets implant-magnetic attachments could offer an average of 14.7 N retentive force for lower complete dentures, which could meet various functional needs of the prostheses, but magnetic retentive force decreased as the applying time goes on the magnetic retainers should be changed after two years; negative rate of bone absorption on implant-bone surface was 92.6%; negative rate of gingival inflammation was 91.3%. The implant-magnetic attachments offer realize reliable retention, don't transmit lateral force to implants. Patients can insert and remove the prostheses and clean the implants and defect cavities conveniently. The above advantages are benefit to tissue health and functions of the prostheses. So, implant-magnetic attachments can be used in the restoration of various oral and maxillofacial defects.
为评价MDIC种植磁附着体在口腔颌面部修复体中的应用效果，对38例采用种植磁附着体修复口腔颌面部缺损的患者进行了1至4年的随访。通过测量修复体的固位力、X线检查及临床检查对效果进行评价。结果显示：修复成功率为94.7%；两组种植磁附着体可为下颌全口义齿提供平均14.7N的固位力，能满足修复体的各种功能需求，但随着使用时间延长磁固位力下降，两年后应更换磁体；种植体-骨界面骨吸收阴性率为92.6%；牙龈炎症阴性率为91.3%。种植磁附着体可实现可靠固位，不向种植体传递侧向力。患者可方便地摘戴修复体并清洁种植体及缺损腔。上述优点有利于组织健康及修复体功能。因此，种植磁附着体可用于各种口腔颌面部缺损的修复。
