3D手术导板在牙周骨皮质切开术中的应用研究

Application of 3D Surgical Guide Plate in Periodontal Corticotomy

目的:探索3D手术导板在骨皮质切开术中的应用效果。方法:收集就诊于我院的20例正畸患者,分为对照组(A)和试验组(B),A组行传统骨皮质切开术,B组行3D导板结合微创骨皮质切开术。分别记录2组患者在术前、术后6周、12周、24周的PPD、mGI以及术后口腔健康生活质量和瘢痕评分。结果:术前,2组各观察指标差异无统计学意义。两组术后6周、12周、24周PPD、mGI与基线相比差异无统计学意义;术后3 d、7 d两组OHIP-14差异有统计学意义(P<0.05);术后24周两组瘢痕评分差异有统计学意义(P<0.05)。结论:3D手术导板结合微创骨皮质切开术可有效改善患者术后不适,美学效果较好。

Objective:To explore the application of 3D surgical guide plate in periodontal corticotomy.Methods:Twenty orthodontic patients admitted to our hospital were collected and divided into control group(A)and test group(B).Group A received traditional corticotomy,while group B received 3D guide plate combined with minimally invasive corticotomy.PPD,mGI,oral health quality of life,and scar score of two groups of patients were recorded before operation,6 weeks,12 weeks,and 24 weeks after operation,respectively.Results:Before operation,there was no significant difference between two groups.There was no significant difference in PPD and mGI between two groups 6 weeks,12 weeks,and 24 weeks after operation in contrast to baseline.The difference of OHIP-14 between two groups at 3 and 7 days after operation was statistically significant(P<0.05).There was significant difference in scar score between two groups 24 weeks after operation(P<0.05).Conclusion:3D surgical guide plate combined with minimally invasive corticotomy can effectively improve postoperative discomfort of patients with good aesthetic effect.
