种二段式牙科种植体

本发明公开了种二段式牙科种植体，包括植体、基台、中央螺丝和密封圈，所述植体内设有与中央螺丝相适配的盲孔，植体与基台通过中央螺丝固定连接，所述密封圈位于植体与基台之间，所述植体包括沉头连接台和药液通道，所述密封圈与沉头连接台抵接，所述药液通道具有注入口和流出口，所述注入口位于沉头连接台，所述流出口位于植体的外壁。该植体增设有注入口、药液通道和流出口，可以根据患者牙床骨特点设计药液通道流向和流出口位置，使得对于患者易发生病变处设计呈现较大密度分布。在患者完成种植修复后，可以通过卸下基台和密封圈，对药液通道注入杀菌药液或促进骨骼与植体结合的药液，以达到减少牙床骨感染和提高骨骼与植体结合程度的目的。 The invention discloses a two-section dental implant.
