■通常进行口腔修复以治疗患有错牙合和牙列缺损的患者。然而,单口腔修复不能正确纠正牙齿的不和谐,牙弓和其他受错牙合影响的部位,一些患者可能由于修复不良而难以恢复咬合功能。
■本研究旨在研究正畸结合纤维增强复合树脂粘合固定局部义齿(FRC-RBFPD)对垂直颌间间隙最小的前牙列缺损的影响。
■本研究纳入了2021年3月至2023年5月间入住我们医院的62例前牙列缺损且下颌垂直间隙最小的患者。将参与者分为观察组(31例)和对照组(31例)。根据治疗计划。对照组采用传统疗法,观察组采用正畸联合FRC-RBFPD治疗。牙周病(牙周袋深度[PD],菌斑指数[PLI],沟出血指数[SBI]),龈沟液中炎症因子水平(高迁移率族蛋白1[HMGB1]),骨髓细胞触发受体-1(TREM-1),单核细胞趋化蛋白-1(MCP-1),疼痛(视觉模拟量表[VAS]),收集并比较两组患者的临床缓解率和不良反应发生率。
■治疗后1、3、5和9个月,警局的分数,PLI,SBI,HMGB1,VAS,观察组TREM-1和MCP-1均低于对照组(FPD治疗=352.532,FPLI评分治疗=112.341,FSBI评分治疗=79.479,FVAS评分治疗=96.132,FHMGB1治疗=52.532,FTREM-1评分治疗=64.593,FMCP-1评分治疗=53.582),差异均有统计学意义。两组之间的反应率存在统计学上的显着差异(97.77%vs.80.65%,χ2=4.026,P=0.045)。两组不良反应发生率无统计学差异(6.45%vs.16.13%,χ2=1.449,P=0.229)。
■正畸结合FRC-RBFPD对前牙列缺损和最小垂直颌间间隙的患者显示出理想的修复效果。
UNASSIGNED: Prosthodontics are often performed to treat patients with malocclusion and dentition defects. However, single prosthodontics cannot properly correct the disharmony of teeth, dental arch and other parts affected by malocclusion, and some patients may have difficulty in recovering the occlusal function due to poor prosthodontics.
UNASSIGNED: This study aims to investigate the effect of orthodontics combined with fibre-reinforced composite resin-bonded fixed partial denture (FRC-RBFPD) on anterior dentition defects with minimal vertical intermaxillary space.
UNASSIGNED: Sixty-two patients with anterior dentition defects with minimal vertical mandibular space admitted to our hospital between March 2021 and May 2023 were enrolled in this study. The participants were divided into the observation group (31 cases) and the control group (31 cases), according to the treatment plan. The control group was treated with traditional therapy, and the observation group was treated with orthodontic combined FRC-RBFPD therapy. Periodontal conditions (periodontal pocket depth [PD], the plaque index [PLI], the sulcus bleeding index [SBI]), levels of inflammatory factors in gingival crevicular fluid (high mobility group box 1 [HMGB1]), myeloid cell triggering receptor-1 (TREM-1), monocyte chemoattractant protein-1 (MCP-1), pain (visual analogue scale [VAS]), the clinical response rate and the incidence of adverse reactions were collected and compared.
UNASSIGNED: After 1, 3, 5 and 9 months following treatment, the scores of the PD, PLI, SBI, HMGB1, VAS, TREM-1 and MCP-1 in the observation group were found to be lower than those in the control group (FPD treatment= 352.532, FPLI score treatment= 112.341, FSBI score treatment= 79.479, FVAS score treatment= 96.132, FHMGB1 treatment= 52.532, FTREM-1 score treatment= 64.593, FMCP-1 score treatment= 53.582, and they were all statistically significant P< 0.05). There was a statistically significant difference in the response rate between the two groups (97.77% vs. 80.65%, χ2= 4.026, P= 0.045). No statistically significant difference was observed in the incidence of adverse reactions between the two groups (6.45% vs. 16.13%, χ2= 1.449, P= 0.229).
UNASSIGNED: Orthodontics combined with FRC-RBFPD shows an ideal restorative effect on patients with anterior dentition defects and minimal vertical intermaxillary space.
