Effect of Removable Denture and Fixed Denture on Occlusal Function and Inflammation Index in Patients with Denture Defect Repaired by Porcelain Crown
Objective To analyze the effect of removable denture and fixed denture on occlusal function and inflammation index in patients with denture defect repaired by porcelain crown.Methods A total of 78 patients with dental defects admitted to the hospital from October 2022 to December 2023 were selected as the research subjects and were randomly divided into a control group and an observation group using a computer random number table method, with 39 cases in each group.Both groups underwent porcelain crown restoration.On this basis, the control group used removable dentures, while the observation group used fixed dentures.T he total effective rate, occlusal function, inflammatory factors, and oral health status of the two groups before and after treatment were compared.Results The total effective rate of the observation group was 94.87％, which was higher than the control group's 79.49％, and the difference was statistically significant (P<0.05).Before the start of treatment, the levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6 (IL-6) and the scores of sulcus bleaching index (SBI), plaque index (PLI), oral health impact profile-14 (OHIP-14) showed no statistically significant differences (P>0.05);after 6 months of treatment, the levels of TNF-α, IL-1β, IL-6 and the scores of PLI, SBI, OHIP-14 in the observation group were (0.28 ±0.04)μg/L, (0.31 ±0.07)μg/L, (9.21 ±0.20)pg/mL, (0.59 ±0.14) points, (1.24 ±0.31) points and (10.91 ±0.12) points respectively, which were lower than (0.39 ±0.06)μg/L, (0.47 ±0.10)μg/L, (11.73 ±0.41)pg/mL (1.27±0.33) points, (2.11±0.37) points and (16.22±0.19) points of the control group, the differences between the groups were statistically significant (P<0.05).Before the start of treatment, there were no statistically significant differences in chewing efficiency and bite force between the two groups (P>0.05);after 6 months of treatment, the chewing efficiency and bite force of the observation group were (91.24±0.31)％ and (140.91±10.12)lbs, respectively, which were higher than (87.11± 0.37)％and (131.22±10.19) lbs of the control group, the differences between the groups were statistically significant (P<0.05).Conclusion Compared with removable dentures, the use of fixed dentures in porcelain crowns for repairing dental defects can improve the patient's occlusal function, reduce inflammatory stimulation, protect periodontal tissue, improve oral health, and have higher practicality.
