Description

口腔种植学科涉及医学、电子、机械、材料、力学等学科。其中,种植义齿是一门跨学科的医疗技术,被广泛应用于牙列缺失的修复。Dental implantology involves medicine, electronics, machinery, materials, mechanics and other disciplines. Among them, implant denture is an interdisciplinary medical technology, which is widely used in the restoration of missing teeth.

种植义齿是将与人体有良好组织相容性的纯钛牙种植体,通过微创手术植入缺牙部位,经过一段时间达到骨整合后,再在人工牙根上连接义齿以修复缺失的牙齿,最大限度的恢复缺失牙的功能。但是种植义齿的一大缺点是:现有牙种植体压应力集中点在牙槽骨和软组织界面上,经过长期的使用,牙槽骨水平面会下降,牙种植体的稳定性会降低。Implant dentures are pure titanium dental implants that have good tissue compatibility with the human body. They are implanted into the missing teeth through minimally invasive surgery. After a period of time to achieve osseointegration, the dentures are connected to the artificial tooth roots to repair the missing teeth. To maximize the function of missing teeth. However, a major disadvantage of implant dentures is that the compressive stress of the existing dental implants is concentrated on the interface between the alveolar bone and soft tissue. After long-term use, the level of the alveolar bone will decline, and the stability of the dental implant will decrease.

可见,现有牙种植体易使牙槽骨水平面下降,稳定性不高。It can be seen that the existing dental implants tend to lower the level of the alveolar bone, and the stability is not high.
