And all the items are significantly discriminated between the group with 3 months and control group without treatment (P < 0.05), and 6 months and control group (P < 0.05),however, the items of JP, MP, PI of 3 months and 6 months are not(P>0.05). Conclusion Occlusal splint removable partial denture is not only appropriate for dentition defect and severely worn dentition but also effective for the treatment of TMD with soft resilient splint. splint.
