种植外科导板是一种能够传递术前骨质、骨量、种植方案等多方面信息的载体,通过导板确定种植体的数目、位置、方向、角度和深度,指导术中种植体的准确植入,提高手术的准确度及种植修复效果.如今,在传统外科导板制作的基础之上,许多国内外学者结合种植外科导板实际临床运用经验,完成了各种改良式种植导板的制作.近年来,随着锥体束CT的广泛应用和数字化口腔种植技术的普及,种植外科导板也从基于模型制作的传统外科导板发展为通过CAD/CAM技术制作的数字化外科导板.“,”Implant surgical guide is a kind of carrier that can transmit the information of preoperative bone, bone mass, planting plan and so on. The number, position, direction, angle and depth of the implant can be determined by the surgical guides to enhance the quality of implantation, Improve the accuracy of the operation and planting restoration effect. Now, on the basis of the traditional surgical guides, many domestic and foreign scholars combined with the practical clinical experience of planting surgical guides, completed a variety of improved planting surgical guides. In recent years, with the widespread use of cone beam computed tomography and the popularization of digital oral implantation techniques, plaster model based surgical guides making technology is being replaced by CAD/CAM.
