Abstract

Recently, a novel magnetic attachment with extremely low cost and high performance was developed. This article aims to introduce a novel magnetic attachment and to evaluate its basic eligibility for denture retention in clinical practice. The novel magnetic attachment system used in this study was the direct-bonding root-keeper-type Magteeth™ MT800 (MagneDesign, Nagoya, Japan). The retentive force without displacement (position 0) and after horizontal displacement to positions 0.5, 1, 1.5, 2, 2.5, and 3 mm were measured. The values relative to the retentive force without displacement were gradually decreased to 82.7 ± 16.3%, 68.8 ± 17.1%, 62.4 ± 15%, 47.2 ± 13.1%, 35.7 ± 9.9%, and 20.7 ± 6.5%, respectively. The retentive force and magnetic field strength did not change significantly after the load test (100 N load, 10,000 times). No new gap between the metal and resin was found in the root keeper- and magnet assembly-embedded blocks after the load test. Some scratches on magnetic assembly and root keeper surface, while no change in the resin texture after the load test were observed. Based on the findings of this preliminary study, this novel low-cost magnetic attachment exhibited favorable retention, strength, and durability for clinical use.
采用高频热处理和冲压技术制造的新型磁性附着系统:介绍及基本性能
近年来,研制出了一种低成本、高性能的新型磁性附着体。本文旨在介绍一种新型磁性附着体,并评估其在临床实践中用于义齿固位的基本资格。本研究中使用的新型磁性附着系统是直接粘接护根器型Magteeth™MT800 (MagneDesign, Nagoya, Japan)。测量无位移(0位)和水平位移至0.5、1、1.5、2、2.5、3mm位置后的固位力。相对于无位移固位力的数值逐渐降低,分别为82.7±16.3%、68.8±17.1%、62.4±15%、47.2±13.1%、35.7±9.9%和20.7±6.5%。负载试验(100 N负载,10000次)后,固相力和磁场强度无明显变化。负载试验后,在根保持器和磁铁组件嵌入块中未发现金属和树脂之间有新的间隙。磁性组件和护根器表面有划痕,但负载试验后树脂织构无变化。基于这项初步研究的结果,这种新型低成本磁性附着体具有良好的固位性、强度和耐久性,可用于临床应用。
