由于局部义齿结构比较复杂,自净作用较差,易造成口腔不洁,余牙易患龋病和牙周病。资料表明,局部义齿与其基牙根面龋的发生有关.由表1可见有修复体的基牙龋患率较低,表2显示龋坏的好发部位与基牙修复体的种类有关,如采用全冠修复者患龋较少。

Due to the complex structure of partial dentures, poor self-purification effect, easy to cause oral unclean, residual teeth susceptible to dental caries and periodontal disease. The data show that the partial denture and root abutment caries on its occurrence.From Table 1 shows the restoration rate of abutment caries lower, Table 2 shows the occurrence of caries lesions and the type of abutment prosthesis, such as the use of all Coronary restoration less caries.
