Passive-tension flap closure of primary wounds remains the most important factor for achieving predictable bone augmentation outcomes. So far, no specific surgical technique has been proposed for major flap advancement, specifically in the thin tissue phenotype (≤ 1.5 mm thick). This article illustrates a detailed description of the Mucosal Detachment Technique (MDT), which separates the mucosal tissue from the underneath periosteum and aims to achieve adequate flap flexibility to cover high-volume augmentation in the thin tissue phenotype. Separating the mucosa from the periosteum allows maintenance of vascularization and an even distribution of tension among the advanced flap. The MDT allows bone augmentation procedures in thin tissue phenotype flap. The flap advancement permits tension-free primary closure in all tissue phenotypes (both thin and thick), independent of the degree of volume augmentation.
被动张力皮瓣关闭是实现可预测骨增量效果的最重要因素。到目前为止，还没有针对主要皮瓣推进的特定手术技术提出，特别是在薄组织表型（≤1.5 毫米厚）中。本文详细描述了黏膜分离技术（MDT），该技术将黏膜组织与下方的骨膜分离，旨在使皮瓣具有足够的柔韧性，以覆盖薄组织表型中的大容量增量。将黏膜与骨膜分离可以保持血管化，并使高级皮瓣之间的张力均匀分布。MDT 允许在薄组织表型皮瓣中进行骨增量手术。皮瓣推进可在所有组织表型（包括薄和厚）中实现无张力的一期闭合，与体积增量程度无关。
