The invention discloses an implant lengthening part. One end of the growing body is connected with a connecting part and the other end is connected with a base platform. The lengthening part of the implant is inclined to one end of the base table, and one end of the length part of the implant is provided with a thread A at one end of the base table, and the thread A is arranged along the oblique surface. The screw is arranged in the direction of the slope. The radial section of A is parallel to the inclined plane; the lower part of the thread A is provided with thread B, and the radial section of the thread B is arranged along the horizontal direction. The inner diameter of the thread is 1/3 to 1/5 of the inner diameter of the thread A; the connecting part of the lengthening part of the implant is connected with the implant, and the bottom is provided with a circle of concave grooves, and the lengthened parts of the implant and the implant. The end of the implant connection is provided with a notch at the bottom axial direction, and the implant lengthening component is connected with a screw thread at the end of the base station. The implant is a long part, which connects the base platform to a slope structure, which can effectively solve the non vertical operation of the implant and the gingival surface, and facilitate the installation of the base and the crown of the teeth.
【技术实现步骤摘要】
一种种植体加长部件
本专利技术涉及一种种植体加长部件,属于口腔种植领域。
技术介绍
随着口腔种植技术的不断发展,“人工植牙”的技术渐趋成熟和稳定。人工植牙是先将生物相容性高的钛金属人工牙根置入齿槽内固定并缝合,并经过数个月后待人工牙根与齿槽内的骨头连接稳固后,再进行后续义齿安装。由于人工牙根是直接与骨头连接,能提供较佳的支撑力。因其可对较硬的食物进行咀嚼而广受欢迎。由于每个人的牙槽骨发育的情况不同,尤其是在牙齿缺失,牙槽骨退化的情况下,或者是为了避免伤及神经的情况下,需要斜着植入种植体,此时,种植体与牙龈面呈现一定的角度,不利于安装基台和牙冠。另外,并非所有的牙龈面都是水平的,不利于基台和牙冠的安装。
