文题释义:
拔牙位点保存:为了预防及减少牙槽嵴的失用性萎缩吸收及牙龈乳头的退缩,使牙槽嵴骨量的高度、宽度及密度满足后期种植的需要,并使牙龈乳头恢复正常高度,以满足美学要求的一种方法。
引导组织再生术:是用外科方法放置一个物理屏障,来选择性地分隔不同的牙周组织,阻止牙龈上皮和牙龈结缔组织向根面生长,造成空间,诱导具有牙周组织再生潜力的牙周膜细胞冠向移动并生长分化,实现牙周膜、牙槽骨、牙骨质再生,形成牙周新附着。
 
 
背景:可吸收丝素修复膜具有较好的机械强度、可降解和良好的组织亲和性,同时有非常好的屏障作用。
目的:评价可吸收丝素修复膜用于拔牙后牙槽嵴位点保存的安全性和有效性。
方法:纳入130例拔牙术后拟行牙槽嵴位点保存患者,随机分2组,试验组65例采用可吸收丝素修复膜进行拔牙后牙槽嵴位点的保存,对照组65例采用可吸收生物膜进行拔牙后牙槽嵴位点的保存。术后7 d,观察黏膜愈合情况;术后7 d、4个月拍摄锥形束CT,观察治疗区域牙槽嵴高度与宽度。

结果与结论:①并发症:术后7 d,两组均未出现感染和下唇麻木情况,对照组1例发生窗口裂开情况,试验组和对照组各出现1例膜暴露情况;②组内比较:与术后7 d相比,试验组、对照组术后4个月的牙槽嵴高度及宽度明显降低(P < 0.05);组间比较:试验组与对照组牙槽嵴高度变化、牙槽嵴宽度变化及附着龈宽度变化比较均无差异;④结果表明,可吸收丝素修复膜用于拔牙后牙槽嵴位点保存具有良好的安全性和有效性;⑤试验经郑州大学第一附属医院伦理委员会批准,伦理审批注册号:ZDY17002;试验已经在中国临床试验中心注册,注册号:ChiCTR-IOR-17025031。

Abstract:

BACKGROUND: Absorbable silk fibroin film holds good mechanical strength, degradability, tissue affinity, and excellent barrier effect.

OBJECTIVE: To evaluate the safety and efficacy of absorbable silk fibroin film for the preservation of alveolar ridge after extraction.
METHODS: A total of 130 patients undergoing alveolar ridge preservation after extraction were randomly divided into two groups, and were then treated with absorbable silk fibroin film (trial group, n=65) or absorbable biofilm (control group, n=65) for the preservation of alveolar ridge after extraction. At 7 days postoperatively, the mucosal healing was observed. Cone-beam CT was taken at 7 days and 4 months postoperatively to observe the height and width of alveolar ridge in the treated area.
RESULTS AND CONCLUSION: At 7 days after surgery, no infection or lower lip numbness occurred in the two groups. In the control group, one case showed window rupture, and one case of each group had membrane exposure. Compared with those at 7 days after surgery, the height and width of alveolar ridge were significantly decreased in both groups at 4 months after surgery (P < 0.05). The changes in the height and width of alveolar ridge and attachment width showed no significant differences between two groups. Our results manifest that the absorbable silk fibroin film is safe and effective for the preservation of alveolar ridge after extraction. The trial has been approved by the Committee of the First Affiliated Hospital of Zhengzhou University (approval number: ZDY17002), and registered at the China Clinical Trial Center with registration number: ChiCTR-IOR-17025031.
