After tooth extraction, the alveolar bone loses volume in height and width over time, meaning that reconstructive procedures may be necessary to perform implant placement. In the maxilla, to increase the bone volume, a mini-invasive surgery, such as a sinus lift using the crestal approach, could be performed.
A crestal approach was used in this study to perform the sinus lift, fracturing the bone and inserting collagen (Condress). The single dental implant was placed in the healed bone after six months.
The newly formed bone was histologically analyzed after healing. Histomorphological analyses confirmed the quality of the new bone formation even without graft biomaterials. This is probably due to the enlargement of the space, meaning more vascularization and stabilization of the coagulum.
Using just collagen could be sufficient to induce proper new bone formation in particular clinical situations, with a minimally invasive surgery to perform a sinus lift.
拔牙后，牙槽骨的高度和宽度会随着时间逐渐减少，这意味着可能需要进行重建手术才能植入种植体。在上颌骨中，为增加骨量，可以进行微创外科手术，例如采用嵴顶入路的上颌窦提升术。
本研究采用嵴顶入路进行上颌窦提升术，将骨块折断并植入胶原蛋白（Condress）。六个月后，在愈合的骨组织中植入单个牙种植体。
愈合后对新形成的骨组织进行组织学分析。组织形态学分析证实，即使不使用移植生物材料，新骨形成的质量也良好。这可能是由于空间扩大，意味着血凝块的血管化程度更高且更稳定。
在特定临床情况下，仅使用胶原蛋白并结合微创上颌窦提升术，可能足以诱导适当的新骨形成。
