The comparision of the effects of different occlusal reconstruction on elderly patients with severe tooth wear and tooth lost

Objective: To explore and compare the effects of occlusal reconstruction with occlusal splint removable denture and fixed denture on elderly patients with severe tooth wear and tooth lost.Methods: 24 patients with severe tooth wear and tooth lost were divided into two groups,15 in occlusal splint removable denture group,and 9 in fixed denture group.Their feelings(esthetic feeling,comfort),clinical symptoms,masticatory efficiency and temporomandibular joint disease symptoms(TMJDS) were observed and analyzed before and after occlusal reconstruction.Results: The patients were all satisfied with their prosthesis.Their clinical symptoms,masticatory efficiency were improved.Statistical analysis showed the significant difference before and after occlusal reconstruction(P0.01).The fixed denture had better effects than the occlusal splint removable denture(p0.05)on patients'feeling and masticatory efficiency.The TMJDS were all improved after occlusal reconstruction.There was no significant difference between the two methods.Conclusions: Occlusal reconstruction using occlusal splint removable denture and fixed denture was effective to improve the elderly patients'oral and occlusal function.The TMJDS can also be improved.The fixed denture has better effect on esthetics,feeling,comfort and masticatory efficiency.
