The relationship between the thickness of reserved space for individual trays and the restoration effect of low and flat alveolar ridge edentulous dentures
Objective Exploring the relationship between different reserved space thicknesses of indi-vidual trays and the restoration of edentulous dentures with a low and flat alveolar ridge.Methods 75 edentulous patients with low and flat alveolar ridge who were treated in the hospital from March 2020 to March 2023 were se-lected and randomly divided into Group A(n=25),Group B(n=25),and Group C(n=25)using a random number table method.The three groups were treated by fabricating individual trays and restoring dentures with no re-served space(0 mm),reserved space(1.5 mm)and(2 mm),respectively.Compare the general information,repair efficiency,VAS score,TMD,and PES scores of the three groups of patients,and analyze the satisfaction scores of the three groups of patients after restoration.Use a generalized estimation equation model to evaluate the improve-ment of various indicators in three groups of patients.Results There were significant differences among the three groups in the deviation values of the final impression from tissue surface,number of follow-up visits,and tender-ness sites,with Group B＜Group C＜Group A(P＜0.05).The total effective rate of Group B was higher than that of Group A and Group C(P＜0.05).Three months after surgery,there was no significant difference in VAS scores among the three groups of patients,and TMD scores of Group B were significantly lower than those of Group A and Group C,while PES scores were significantly higher than those of Group A and Group C(P＜0.05).Comparing the satisfaction of three groups of patients with regard to retention effect,stability,chewing function,and comfort,the satisfaction of Group B was significantly higher than that of Group A and Group C(P＜0.05).By generalized es-timation equation analysis,it was shown that Group B had superior improvement in TMD score,PES score,reten-tion effect,stability,chewing function,and comfort than Group A and Group C,while Group C had better improve-ment in all aspects than Group A.Conclusion Individual trays with reserved space(1.5 mm)produced a better fit of the final denture tissue surface to the mucosal morphology,fewer follow-up visits and tenderness sites for the pa-tient,improved restoration outcomes,and a higher level of patient satisfaction.
