Clinical analysis of the design of removable partial denture in dental caries of abutment teeth

Objective To malce research into the relationship between different designs of removable partial denture and dental caries of abutment teeth.Methods Depending on the practical condition of 156 patients who suffered from dentition defect,we designed tooth and mucosa supporting denture,and mucosa supporting denture on the basis of Kennedy's classification,then we examined the results of abutment teeth to see dental caries and oral hygiene before the patients wore the denture and after they wore the denture for 3 years and 5 years.Results There was a close relationship between the different designs of restoration and the oral hygiene of abutment teeth;the four types of the design of dentition defect were different,but there was no distinct difference among them(P 0.05);the frequency of dental caries of the patients whose cavity health conditions were poor was much more than the patients whose cavity health conditions were good,the difference being of great importance(P 0.05).Conclusion If the unreasonable design and making of removable partial denture is applied to the patients' mouth,when the cavity health conditions of the patients are poor,the patients will suffer from the decay of abutment teeth and the adjacent teeth,which will affect the oral cavity and even the general health of the patients.
