The conventional protocol for lateral guided bone regeneration (GBR) in esthetic areas requires the securing of resorbable collagen membranes using titanium cortical bone pins to immobilize bone grafts. These procedures are highly invasive and can increase patient morbidity and discomfort. Herein, we introduce a minimally invasive novel resorbable membrane pouch technique, wherein collagen membranes can be immobilized by securing them to the periosteum without the need of titanium pins. We describe 11 cases of single-immediate- or delayed-implant placement in the atrophic maxilla esthetic zone. All implants were successful and functional without pain or inflammation and with optimal soft-tissue health and esthetics. Radiographic evaluation with cone-beam computed tomography (CBCT) and esthetic assessment using the pink esthetic score (PES) were performed. At the time of implant placement, the average augmented bone width was 2.8 ± 0.6 mm on CBCT analysis. In all cases, resorption of the augmented bone was confirmed with an average of -1.3 ± 0.8 mm. Soft-tissue outcomes were scored 1 year after permanent restoration. The PES score 1 year after treatment was 11.9 ± 1.4. The resorbable membrane pouch technique with immediate or delayed implant placement for buccal dehiscence in the esthetic area can be predictable and is minimally invasive.
美学区域侧向引导骨再生（GBR）的传统方案需要使用钛皮质骨钉固定可吸收胶原膜，以固定骨移植材料。这些操作具有高度侵入性，会增加患者的发病率和不适感。在此，我们介绍一种微创新型可吸收膜袋技术，其中胶原膜可通过固定于骨膜而无需钛钉来实现固定。我们描述了11例在萎缩性上颌美学区域进行单颗即刻或延期种植体植入的病例。所有种植体均成功且功能良好，无疼痛或炎症，软组织健康和美学效果最佳。使用锥形束计算机断层扫描（CBCT）进行影像学评估，并使用粉色美学评分（PES）进行美学评价。在种植体植入时，CBCT分析显示平均增宽骨宽度为2.8±0.6mm。在所有病例中，均证实增宽骨有吸收，平均吸收量为-1.3±0.8mm。在永久修复1年后对软组织结果进行评分。治疗1年后的PES评分为11.9±1.4。用于美学区域颊侧骨缺损的可吸收膜袋技术联合即刻或延期种植体植入可获得可预测的效果，且具有微创性。
