Magnetic attachment improves the chewing ability of patients with dental defects after oral restoration

To investigate the effect and clinical value of magnetic attachments in oral restoration.

Seventy-two cases of dental defects treated in Haishu District Stomatological Hospital from April 2018 to October 2019 were selected for retrospective analysis, of which 36 cases were treated with routine oral restoration (control group) and 34 cases with magnetic attachments (research group). The clinical efficacy, adverse reactions, masticatory efficiency and fixation force were compared between the two groups, and the treatment satisfaction was investigated at discharge. Subsequently, a one-year follow-up survey was conducted on the patients. The probing depth (PD) and alveolar bone height were re-examined at 6-month intervals, and the sulcus bleeding index (SBI), tooth loosening and plaque index (PLI) were recorded.

Compared with the control group, the total effective rate was higher in the research group, and the incidence of adverse reactions was lower (P<0.05). After the restoration treatment, the masticatory efficiency, fixation force, comfort and aesthetic outcome in the research group were higher than those in the control group (all P<0.05). The follow-up results showed that the SBI, PD, PLI and tooth loosening rate of the research group were lower while the alveolar bone height were higher, versus the control group (all P<0.05).

Magnetic attachments can significantly improve the effect and safety of dental restoration as well as the masticatory efficiency, fixation, and periodontal rehabilitation of patients, which fully illustrates the clinical application value of magnetic attachments.
