Effects of implant attachment complete denture and traditional complete denture restoration on alveolar ridge absorption and oral health-related quality of life
Objective:To analyze the effects of implant overdenture restoration with Locator attachment fixation meth-od and traditional complete denture restoration on the absorption of mandibular alveolar ridge and oral health-related quality of life.Methods:A total of 62 patients with mandibular dentition loss and moderate to severe alveolar ridge resorption admit-ted to the hospital from October 2019 to February 2022 were selected as the study subjects.They were randomly divided into the observation group(n=32)and control group(n=30).The control group received traditional complete denture restoration,while the observation group implanted 2～4 Straumann implants in each anterior mandibular area.Subsequently,an appropri-ate Locator attachment abutment was used to assist in the restoration of the overdenture.Compare the chewing function and alveolar ridge absorption of two groups of patients,and record the oral health-related quality of life(OHIP-14)and degree of satisfaction of denture wearing at each time point after restoration.Results:The speech clarity,bite force,chewing efficiency and frequency of the observation group were higher than those of the control group(P＜0.05).After 6 months of complete denture restoration,the alveolar ridge absorption and OHIP-14 scores in the anterior and posterior tooth areas of the observa-tion group were lower than those in the control group(P＜0.05).The degree of satisfaction of denture wearing was higher than that of the control group(P＜0.05).Conclusion:Locator attachment is more effective in maintaining stability in severely a-trophic edentulous mandibular restoration.It not only improves chewing function,but also enhances oral health-related quality of life,resulting in better satisfaction with denture wearing.
