Three-dimensional (3D) planning in oral and maxillofacial surgery has become a standard in the planification of a variety of conditions such as dental implants and orthognathic surgery. By using custom-made cutting and positioning guides, the virtual surgery is exported to the operating room, increasing precision and improving results.
We present our experience in the treatment of craniofacial deformities with 3D planning. Software to plan the different procedures has been selected for each case, depending on the procedure (Nobel Clinician, Kodak 3DS, Simplant O&O, Dolphin 3D, Timeus, Mimics and 3-Matic). The treatment protocol is exposed step by step from virtual planning, design, and printing of the cutting and positioning guides to patients' outcomes.
3D planning reduces the surgical time and allows predicting possible difficulties and complications. On the other hand, it increases preoperative planning time and needs a learning curve. The only drawback is the cost of the procedure. At present, the additional preoperative work can be justified because of surgical time reduction and more predictable results. In the future, the cost and time investment will be reduced. 3D planning is here to stay. It is already a fact in craniofacial surgery and the investment is completely justified by the risk reduction and precise results.
口腔颌面外科的三维（3D）规划已成为种植牙和正颌外科等多种病症规划中的标准操作。通过使用定制的切割和定位导板，虚拟手术可应用于手术室，提高了精度并改善了手术效果。
我们介绍了在3D规划治疗颅面畸形方面的经验。根据手术类型（诺贝尔临床医生软件、柯达3DS软件、Simplant O&O软件、海豚3D软件、Timeus软件、Mimics软件和3-Matic软件），为每个病例选择了用于规划不同手术步骤的软件。从虚拟规划、切割和定位导板的设计与打印到患者的治疗结果，逐步阐述了治疗方案。
3D规划减少了手术时间，并能够预测可能出现的困难和并发症。另一方面，它增加了术前规划时间，且需要一个学习过程。唯一的缺点是手术成本。目前，由于手术时间的减少和更可预测的结果，额外的术前工作是合理的。未来，成本和时间投入将会降低。3D规划将持续存在。它在颅面外科中已经成为现实，通过降低风险和获得精确的手术效果，这种投入是完全合理的。
