Clinical effect of i-PRF combined with Bio-OSS bone powder in tooth extraction site preservation
应用i-PRF复合Bio-Oss骨粉在拔牙位点保存中的临床效果研究

摘要

目的 探讨分析i-PRF复合Bio-Oss骨粉拔牙位点保存技术应用于口腔种植患者中的临床治疗效果及对美学指数、主观满意评分的影响。方法 选取2021年1月至2022年6月在我院收治的41例单颗牙微创拔除的患者作为研究对象，按照随机数字表法将其分为对照组（21例）与实验组（20例）。对照组患者采用拔牙后常规处理，实验组患者则采用i-PRF复合Bio-Oss骨粉拔牙位点保存技术，比较两组患者的种植体存留率、骨结合率，术后1、3个月骨吸收量红色美学指数（PES）、白色美学指数（WES）评分。结果 本次研究显示对照组与实验组患者种植体存留率、术后6个月垂直骨吸收量及咀嚼效能差异无统计学意义（P＞0.05）。结论：在口腔种植技术中对患者进行处理时，选择i-PRF复合Bio-Oss骨粉拔牙位点保存技术，能够有助于改善患者的美学指数以及主观满意评分。

Abstract

Objective To explore and analyze the clinical therapeutic effect of i-PRF combined with Bio-OSS bone meal extraction site preservation technique in oral implant patients and its effect on aesthetic index and subjective satisfaction score.
Methods a total of 41 patients admitted to our hospital from May 2018 to March 2020 with minimally invasive extraction of single tooth were selected as the research objects, and they were divided into control group (21 cases) and experimental group (20 cases) according to random number table method. Patients in the control group were treated with conventional treatment after tooth extraction, while patients in the experimental group were treated with I-PRF combined with Bio-OSS bone meal extraction site preservation technology. The implant retention rate, bone binding rate, and bone absorption scores of red aesthetic index (PES) and white aesthetic index (WES) 1 and 3 months after surgery were compared between the two groups.
Results In this study, there were no significant differences in implant retention rate, vertical bone absorption and chewing efficiency 6 months after operation between the control group and the experimental group (P > 0.05).
Conclusion  s In the treatment of patients with oral implants, the combination of I-PRF and Bio-OSS bone meal extraction site preservation technique can help improve patients' aesthetic index and subjective satisfaction score.
