The use of different membranes is common in dentoalveolar surgery. Absorbable and nonabsorbable membranes are used, often beneath the periosteum, to fulfil different functions (as barriers, patches, or spacers). It is still unclear to what extent such membranes affect the biology of the periosteum and what role is played by piezoelectric devices during preparation of the periosteum. We placed two different membranes (absorbable and nonabsorbable) underneath the periosteum of rat calvaria. We prepared the periosteum using different methods (piezoelectric device vs mechanical device). We then examined and analyzed periosteal microcirculation over a period of 28 days. A clear difference was observed between the two methods when used with absorbable membranes: The piezoelectric device offered advantages. Absorbable membranes maintain considerably more local periosteal microcirculation and should be given preference. In addition, we observed an advantage to using a piezoelectric device for periosteal dissection. Therefore, this method should also be used more widely.
在牙槽外科手术中，使用不同的膜是很常见的。可吸收和不可吸收膜通常在骨膜下使用，以实现不同的功能（作为屏障、补片或间隔物）。目前尚不清楚这些膜在多大程度上影响骨膜生物学，以及在骨膜制备过程中压电装置发挥了什么作用。我们在大鼠颅骨的骨膜下放置了两种不同的膜（可吸收和不可吸收）。我们使用不同的方法（压电装置与机械装置）制备骨膜。然后，我们在28天的时间里检查并分析了骨膜微循环。当与可吸收膜一起使用时，两种方法之间观察到明显差异：压电装置具有优势。可吸收膜能维持更多的局部骨膜微循环，应优先选用。此外，我们观察到使用压电装置进行骨膜剥离有优势。因此，这种方法也应更广泛地使用。
