[Abstract]:Objective to investigate the correlation between the logarithmic (Posterior Occluding Pairs, POPs) of posterior teeth occlusion and oral masticatory function by measuring the masticatory function and swallowing threshold of removable partial denture in patients with dentition defect. Methods according to the number of teeth and the number of occlusal teeth, the patients were divided into four groups: group A (control group) and group A (group D). Group A: at least 28 upper and mandibular teeth, and at least 8 POPs;B groups: at least 10 teeth with a single jaw and at least 5 POPS;. Group C: at least 10 teeth with a single jaw, including 3-4 POPs;D groups: less than 10 teeth in a single jaw, including 1-2 POPs. Oral cavity examination was performed before and one week after treatment, and subjective masticatory function of 8 kinds of food was measured by questionnaire. The objective masticatory function was measured by artificial chewing test. The mastication times and the masticatory time were recorded when the patients reached the swallowing threshold. Result 1. Before repair treatment, the masticatory times of group A reached the threshold of swallowing was 37.73 鹵15.23, group B was 39.30 鹵12.77, group D was 81.40 鹵32.83, which was higher than that of group A (P0.05). After repair treatment, the mastication times of group B (53.6 鹵38.79) and group B (67.71 鹵19.40) were less than those of group C (80.27 鹵21.80) and group B (P 0.05). The mastication times of BCU D group were not significantly repaired after repair (P0.05). 2. Before repair, the masticatory time of group A (29.59 鹵13.86) and group B (30.60 鹵9.91) were less than that of group D (53.00 鹵18.88). After repair treatment, the masticatory time of swallowing threshold in group C (48.86 鹵11.89) was less than that in group C (52.40 鹵11.96) (P0.05). The mastication time of group D to reach swallowing threshold after treatment was not decreased compared with that before treatment (P0.05). 3. The X50 of, A, B, C, D group was 3.31 鹵0.81 鹵0.97 鹵0.97 鹵0.97 鹵0.57 鹵0.50 鹵5.44 鹵0.28, respectively. The objective masticatory efficiency of the control group was higher than that of the experimental group, and that of the B group was higher than that of the D group (P0.05). After repair treatment, the X50 of, A, B, C, D group was 3.31 鹵0.81U 4.19 鹵1.01U 4.57 鹵0.35 鹵4.88 鹵0.42.The objective masticatory efficiency of the control group was still higher than that of the experimental group, and that of the B group was higher than that of the D group, and the masticatory efficiency of the control group was higher than that of the D group. The objective masticatory efficiency in group D was higher than that before treatment (P0.05). 4. In group B, the ability of chewing soft food was improved (1.51 鹵0.61 before treatment and 1.20 鹵0.37 after treatment). In group C, the ability of chewing hard food and soft food was not significantly improved (P0.05) in group), D (2.61 鹵1.46 before treatment, 2.13 鹵1.12 after treatment) and soft food (1.88 鹵0.96 before treatment). The ability of 1.52 鹵0.64) was significantly improved after treatment. 5. With the increase of the number of teeth restored by denture, there was no significant difference in the number of mastications and the masticatory time, the objective masticatory efficiency, the average chewing ability, the masticatory ability of hard food and the ability of soft food when the patients reached the threshold of swallowing. 6. With the increase of the number of POPs in denture restoration, the objective masticatory efficiency, the average chewing ability and the masticatory soft food ability of the patients were significantly improved. Conclusion in dentition, the logarithmic occlusal of posterior teeth is positively correlated with the objective masticatory function. The more logarithmic occlusal pairs of posterior teeth are, the higher the objective masticatory efficiency is, and the less masticatory times and masticatory time are used for swallowing threshold. The logarithmic occlusal of posterior teeth was correlated with subjective masticatory function to some extent, and removable partial denture could improve the objective and subjective masticatory function of patients with dentition defect. The improvement of masticatory function is closely related to the logarithmic occlusal of posterior teeth.
