Current commercially available barrier membranes for oral surgery have yet to achieve a perfect design. Existing materials used are either non-resorbable and require a second surgery for their extraction, or alternatively are resorbable but suffer from poor structural integrity or degrade into acidic by-products. Silk has the potential to overcome these issues and has yet to be made into a commercially available dental barrier membrane. Reactive inkjet printing (RIJ) has recently been demonstrated to be a suitable method for assembling silk in its regenerated silk fibroin (RSF) form into different constructs. This paper will establish the properties of RSF solutions for RIJ and the suitability of RIJ for the construction of RSF barrier membranes. Printed RSF films were characterised by their crystallinity and surface properties, which were shown to be controllable via RIJ. RSF films degraded in either phosphate buffered saline or protease XIV solutions had degradation rates related to RSF crystallinity. RSF films were also printed with the inclusion of nano-hydroxyapatite (nHA). As reactive inkjet printing could control RSF crystallinity and hence its degradation rate, as well as offering the ability to incorporate bioactive nHA inclusions, reactive inkjet printing is deemed a suitable alternative method for RSF processing and the production of dental barrier membranes.
目前市售的口腔外科屏障膜尚未实现完美设计。所使用的现有材料要么不可吸收,需要二次手术取出,要么可吸收,但结构完整性差或降解为酸性副产物。丝绸有潜力克服这些问题,但尚未制成市售的牙科屏障膜。最近已证明反应性喷墨打印(RIJ)是一种将再生丝素蛋白(RSF)形式的丝绸组装成不同结构的合适方法。本文将确定用于RIJ的RSF溶液的性质以及RIJ用于构建RSF屏障膜的适用性。通过其结晶度和表面性质对打印的RSF膜进行表征,结果表明这些性质可通过RIJ进行控制。在磷酸盐缓冲盐水或蛋白酶XIV溶液中降解的RSF膜的降解速率与RSF结晶度相关。RSF膜还与纳米羟基磷灰石(nHA)一起打印。由于反应性喷墨打印可以控制RSF结晶度,从而控制其降解速率,并且能够掺入生物活性nHA夹杂物,因此反应性喷墨打印被认为是RSF加工和生产牙科屏障膜的合适替代方法。
