目的 系统评价牙科盾构技术与传统即刻种植术的临床效果。方法 检索的数据库包括:Cochrane library、ScienceDirect、Pubmed、万方、维普、中国期刊全文、中国科技期刊和中国生物医学文献数据库等,文献时间从各数据库建库至2021-02-10。统计分析采用Revman 5.4.1版软件。结果 共纳入7个RCT,238枚种植体。采用盾构技术的种植体有着和传统即刻种植术一样的成功率(100%)和初期稳定性MD=0.58[－0.24,1.41],P=0.16;术后6个月垂直[MD=－0.49(－0.54,－0.45),P<0.05]和水平[MD=－0.26(－0.39,－0.12),P<0.05]骨吸收量均小于传统即刻, 术后12个月的水平骨吸收量小于传统即刻MD=－0.83[－0.91,－0.75],P<0.05;而且在术后12个月时取得了更好的种植体周围粉红色美学效果MD=1.30[0.93,1.66],P<0.05。结论 盾构技术可以减少美学区种植术后唇颊侧骨板的吸收,提高美学效果。
Abstract
Objective To assess the clinical outcomes of the socket-shield technique and conventional immediate implantation. Methods Such electronic databases as Cochrane library, Science Direct, Pubmed, Wanfang, CJFD, VIP, CQVIP and CBM were searched. Meta-analysis was performed by using Revman 5.4.1. Results Seven randomized controlled trials (RCTs) involving 238 implants were included. The socket-shield technique had the same success rate(100%)and initial stability[MD=0.58(－0.24,1.41),P=0.16>0.05] as the conventional immediate implantation (CII). The amount of vertical[MD=－0.49(－0.54,－0.45),P<0.05] and horizontal[MD=－0.26(－0.39,－0.12),P<0.05] bone resorption at 6 months after operation was smaller than that of CII, so was the amount of horizontal bone resorption at 12 months MD=－0.83[－0.91,－0.75] (P<0.05). A better aesthetic effect around the implant was achieved at 12 months after operation MD=1.30[0.93,1.66] (P<0.05). Conclusions The socket-shield technique can reduce the absorption of the labio-buccal bone plate and improve the aesthetic effect.
