钛制腭托全口义齿的临床应用

目的：观察钛制腭托全口义齿临床应用效果。方法：对100例无牙殆患者采用二次印模法，取功能性印模，常规制作钛腭托全口义齿，并进行1～3年的临床疗效观察。结果：临床应用观察得知，钛制腭托全口义齿固位好，异物感小，基托轻薄，没有金属味，抗折力强。尤其以前曾戴用过PMMA全口义齿的患者更换钛制腭托全口义齿后感觉更舒适，适应期明显缩短。其满意度达85％。其中3例患有轻度口腔干燥症的患者对钛制基托全口义齿满意度明显高于PMMA全口义齿，钛制腭托在3年的使用过程中尚未发现基托折裂现象。但是有40％的患者钛腭托磨光面使用后出现色素沉着，这可能与患者的饮食习惯和口腔卫生以及义齿加工质量有关。
