Abstract:
Objective In this study,we compared the masticatory efficiency,occlusal functional indexes,and satisfaction of lingual-ized occlusion(LO)vs.anatomic occlusion(AO)and discussed the difference between these occlusions.Methods Twenty edentulous patients were included in this clinical trial during 2021 April to December.They were divided into 2 groups according to their denture occlusion.Masticatory efficiency was tested by chewing the same amount of peanuts(by weight)and then the absorption of the solution was compared under a spectrophotometer after wearing dentures for 1 month.The TeeTester occlusion analysis system was used to test masticatory function,and satisfaction research was conducted for the edentulous patients at this time point as well.Finally,statistical analyses were conducted to compare the difference in masticatory efficiency between AO and LO by SPSS 20.0.Results The indexes of LO were worse than AO in masticatory efficiency,masticatory function and most of satisfaction research,while LO was better than AO in speech recovery.The difference was only statistically significant in COF-y of masticatory function(P＜0.05).Conclusion LO is similar with AO in terms of masticatory efficiency,satisfaction and denture stability;LO has good performance in denture's fit and use for patients.
