近年来国外学者为解决口腔及颌面修复体的固位问题,发展了利用磁体磁力增加修复体固位力的磁性固位装置,显著改善了修复体的固位。作者针对国外磁性固位体存在的固位力不足和耐腐蚀性较差的问题,研制了新型(Z—1型)磁性固位体,进一步提高了磁性固位体的固位力和防腐蚀能力,获得了满意的效果。 1 研究方法 In recent years, foreign scholars to solve the problem of oral and maxillofacial prosthesis retention, the development of the use of magnets to increase the retentive force of magnet retention magnetic retention device, significantly improving the retention of the prosthesis. Aiming at the problems of lack of retention force and poor corrosion resistance of foreign magnetic retainers, the authors developed a new type (Z-1) magnetic retainer to further improve the retention and corrosion resistance of magnetic retainers Ability to obtain satisfactory results. 1 research methods
