探讨血管化骨膜-结缔组织夹层( VIP-CT)瓣联合引导骨再生( GBR)技术在前牙美学区种植中的应用,15例患者应用VIP-CT瓣联合GBR技术修复缺牙区软硬组织缺损并同期牙种植,记录术前、术后6个月、术后18个月附着龈宽度。术后6个月及术后18个月附着龈宽度较术前差异有统计学意义(P〈0.05),术后6个月的附着龈宽度与术后18个月相比差异无统计学意义。采用VIP-CT瓣可增加美学区附着龈宽度,短期内效果良好。
This article presented a series of cases using vascularized interpositional periosteal-connective tissue ( VIP-CT) flap with guide bone regeneration ( GBR) in peri-implant soft and hard tissue reconstuction at the esthet-ic zone of maxillary. Fifteen cases with bone and soft tissue defects underwent VIP-CT flap with GBR in the implant treatment. And the attached gingiva width was evaluated before treatment and six months and eighteen months after the operation. The width of attached gingival of six months and eighteen months after surgery was significantly dif-ferent from the preoperative value (P〈0. 05). However, no statistically significant difference could be found at six months and eighteen months postoperative. The application of VIP-CT flap could increase the width of attached gin-giva around implants and the short-term effects were stable and favorable.
