目的:研究磁性附着体用于牙列缺损修复的临床效果及对牙周微生态的影响。方法:选取2014年8月至2015年8月我院接诊的80例牙列缺损患者作为研究对象,按照随机数表法分为观察组40例和对照组40例。对照组采用常规修复,观察组采用磁性附着体治疗,观察两组患者治疗后固定力、咀嚼效力、舒适程度、语言功能、外观及牙周微生态。结果:治疗后,观察组固定力、咀嚼效力大于对照组[(4.07±0.38)N vs(3.10±0.29)N,(0.80±0.23)%vs(0.59±0.21)%],两组比较差异具有统计学意义(P<0.05);观察组舒适程度、语言功能、外观均优于对照组[(4.21±0.45)score vs(3.10±0.42)score,(4.79±0.50)score vs(3.90±0.42)score,(3.98±0.61)score vs(2.76±0.56)score],两组比较差异具有统计学意义(P<0.05);观察组PLI、PD显著小于对照组[(1.34±0.31)°vs(1.49±0.43)°,(1.53±0.29)mm vs(1.67±0.32)mm],两组比较差异具有统计学意义(P<0.05)。结论:磁性附着体治疗牙列缺损疗效显著,能够减少对牙周组织的损伤,提高舒适度和咀嚼功能。
Objective: To study the clinical effect of magnetic attachment on dentition defect repair and its effect on periodontal microflora. Methods: Totally 80 cases of dentition defect admitted to our hospital from August 2014 to August 2015 were selected as study object. According to the random number table, 40 cases were divided into observation group and control group. The control group was treated with routine repair. The observation group was treated with magnetic attachment. The fixation force, masticatory efficacy, comfort level, language function, appearance and periodontal microecology were observed in two groups. Results: After treatment, the fixation and masticatory efficacies in the observation group were significantly higher than those in the control group [(4.07 ± 0.38) N vs (3.10 ± 0.29) N, (0.80 ± 0.23)% vs (0.59 ± 0.21)%] (4.21 ± 0.45) score vs (3.10 ± 0.42) score, (4.79 ± 0.50) score vs (3.90 ± 0.42), respectively (P <0.05). The degree of comfort, language function and appearance in the observation group were better than those in the control group score (3.98 ± 0.61) score vs (2.76 ± 0.56) score], the difference between the two groups was statistically significant (P <0.05). The PLI and PD in the observation group were significantly lower than those in the control group [(1.34 ± 0.31) ° vs ± 0.43) ° and (1.53 ± 0.29) mm vs (1.67 ± 0.32) mm respectively. The difference between the two groups was statistically significant (P <0.05). Conclusion: The magnetic attachments are effective in treating dentition defect, which can reduce the damage to the periodontal tissue and improve the comfort and masticatory function.
