种植体磁性固位下颌覆盖总义齿不同类型基托的应用比较

Comparative Study on Clinical Application Different Base Of Implant Supported Magnetic Retained Overdenture

目的:探讨预防种植体磁性固位下颌覆盖总义齿基托断裂的临床方法。方法:按基托的不同类型把种植体磁性固位下颌覆盖总义齿患者分为三组,第一组为纯塑料基托,第二组为铸造金属塑料联合基托,第三组为成品的不锈钢丝网与塑料联合基托;分别观察义齿功能后断裂情况、患者的满意度、固位力的变化、义齿性口炎的发生率。结果:铸造金属基托的种植体磁性固位下颌覆盖总义齿没有发生断裂现象,患者的满意度高,义齿性口炎发生率明显低(P<0.05),二年内三组义齿的固位力无显著性变化(P>0.05)。结论:提示种植体磁性固位下颌覆盖总义齿利用铸造金属基托可以达到较好的临床效果。

Objective： Study on Clinical way to select the base of implant supported magnetic retained overdenture for the mandibular edentulous patients. Methods： According to the base material divided implant supported magnetic retained mandibular overdenture into three groups： resin base, casting mental acrylic base, ready-made stainless steel net acrylic base. Fracturing of base,satisfaction of patients , changing of magnetic force were measured after placing magnetic attachment respectively. Results： The fracturing of base,satisfaction of patients ,rate of denture stomatitis exist significant differences among three groups. The changing of magnetic retention exists no differences among three groups. Conclusion： It suggests that the casting mental acrylic base be a better base to use in implant supported magnetic retained overdenture for the mandibular edentulous patients .
