可摘局部义齿和全口义齿可能破坏口腔原有的微生态平衡，为口腔微生物的生长和定植创造条件，进而导致诸多口腔疾病等，因此清洁义齿及提高义齿的自洁能力十分重要。清洁义齿的外在方法可以分为机械方法、化学方法和其他方法。机械清洁义齿包括牙刷清洁法和超声清洗法，化学清洁义齿法主要有次氯酸盐类、过氧化物类、酸制剂类、含酶制剂类和天然药物类侵泡等，皆可有效地去除义齿表面的菌斑、牙石和着色，但过氧化物却可能改变义齿树脂的颜色甚至漂白树脂；酸制剂对金属有较强的腐蚀作用，对眼、皮肤和黏膜有刺激作用。义齿自身清洁可以分为义齿基托表面处理和自身处理。前者主要有基托表面电荷改变、基托表面镀纳米非晶金刚石膜和基托表面形成聚电解质多层膜。后者则是将药物控释系统、富组蛋白-5、季铵盐类化合物、脱乙酰壳多糖、纳米载银抗菌剂、二氧化钛和纳米氧化锌物质加入基托树脂材料中，起到较好的杀灭细菌和真菌，抑制龈下细菌黏附的作用。单一的清洁义齿方法尚无较好的清洁效果，因此必须选择复合的清洁方法。

Removal of partial and complete denture could damage the original microecological balance of the oral cavity. Denture removal could create conditions for the growth and engraftment of oral microorganisms, leading to oral diseases. Therefore, cleaning dentures and improving the self-cleaning ability of dentures are important. The methods for cleaning the surface of dentures can be divided into mechanical, chemical, and others. Mechanical methods include brushing and ultrasonic cleaning methods. Chemical methods mainly involve immersing dentures in hypochlorous acid salt agent, peroxide agent, acid agent, enzyme agent, natural medicines, and so on. All the above can effectively remove dental plaque, tartar, and pigmentation. However, the peroxide agent may change the color of the denture resin, and even bleach it. The acid agent exerts strong corrosion effects on the metal material and has harmful effects on the eyes, skin, and mucous membrane. Self-cleaning of dentures can be divided into denture-based surface treatment and simple treatment. The former mainly includes changes in the charge of the denture surface, nanometer amorphous diamond film on the denture surface, and polyelectrolyte multilayer film formed on the denture surface. The latter adds materials of drug controlled-release system, rich histone 5, quaternary ammonium salts, chitosan, nanometer silver-carrying antimicrobial agent, titanium dioxide, and nanometer zinc oxide to the denture resin materials, which will eliminate bacteria and fungi and inhibit subgingival bacterial adhesion. Single denture cleaning method could not obtain the best cleaning effect, so selecting composite cleaning methods is necessary.
