Efficacy observation of occlusal rehabilitation in aged people with serious attrition / 医学研究生学报

ABSTRACT

Objective:To evaluate the efficacy of occlusal rehabilitation in old patients with decreased vertical dimensions caused by serious attrition.Methods:Sixty-five patients with decreased vertical dimension caused by serious attrition were divided into 3 groups according to the defect of dentition and/or TMD.Group A included 42 patients with serious attrition and defection of dentition.Group B had 15 patients with heavy tooth wear,defection of dentition and TMD.Group C included 8 patients with serious attrition and functional TMD.All patients were conducted occlusal rehabilitation at increased vertical dimensions in normal intercuspital position(ICP) by removable denture with occlusal pad and removable occlusal splints.The time of follow-up visit of these patients ranged from 1.5 months to 9 years. Results:The masticatory efficacy of the patients was obviously improved,and all the symptoms of TMD were relieved.Furthermore,the symptoms of TMD were not observed after the treatment in patients without TMD.Conclusion:The results achieved by removable occlusal rehabilitation to aged people with serious attrition and decreased vertical dimension are satisfactory,and suggest that the occlusal rehabilitation is necessary for them.Furthermore,the removable occlusal rehabilitation can be acted as a reference and transition to permanent fixed occlusal rehabilitation.
