The mobility of 50 osseointegrated implants, inserted for improvement of the support of dentures in edentulous lower jaws, was studied during a period of up to 3 years by means of mechano-electronic measurements. The results showed that 3 months after implantation osseointegrated implants have less quasi-static mobility than natural teeth without periodontal lesions. Under the stresses of mastication the mobility of osseointegrated implants continuously increases. After 2-3 years, implants show a similar mobility as natural teeth supporting comparable denture constructions. The Periotest readings of implants were significantly lower than those of natural teeth, largely independent of the date of mobility measurement. A prognosis of functional properties as well as predicting the impending loss of osseointegrated implants is possible with the aid of long-term mobility measurements.
通过机电测量方法，对50颗为改善无牙下颌义齿支撑而植入的骨整合种植体在长达3年的时间内的移动性进行了研究。结果表明，植入后3个月，骨整合种植体的准静态移动性比没有牙周病变的天然牙要小。在咀嚼应力作用下，骨整合种植体的移动性持续增加。2至3年后，种植体的移动性与支撑类似义齿结构的天然牙相似。种植体的牙周探测仪读数明显低于天然牙，且在很大程度上与移动性测量日期无关。借助长期移动性测量，可以对骨整合种植体的功能特性进行预后评估，并预测即将出现的种植体丧失情况。
