AB  - ObjectiveTo investigate the effect of denture stomatitis of selective laser melting (SLM) titanium alloy for removable partial denture frameworks.MethodsTwenty patients with dentition defects in our hospital were divided into two groups according to the different methods of creating a removable partial denture framework: the SLM group and casting group. The success rate, placement rate, masticatory efficiency and incidence of denture stomatitis were compared. Experimental data were analyzed with SPSS20.0.ResultsThe success rate of the SLM framework group was 100.00%, which was higher than that of the casting group (90.00%) (P < 0.01). The rate of framework placement in the SLM group was slightly lower than that in the casting group (P < 0.05). The masticatory efficiency of the SLM group was higher than that of the casting group (0.783 ± 0.030 vs. 0.699 ± 0.037, P < 0.001). The incidence of denture stomatitis (10.00%) in the SLM group was significantly lower than that in the casting group (30.00%) (P < 0.001).ConclusionSLM is superior to the traditional casting method in mastication efficiency and reducing the incidence of denture stomatitis. This method can meet the clinical requirements, but the accuracy of the long-term stent needs to be improved.
